how to prevent laptop explosion?

October 30th, 2009

Thin, high capacity, long life, these are the outstanding characteristics of lithium batteries. For this reason, lithium-ion battery, it has rapidly replaced the nickel-metal hydride, nickel cadmium  hp batterybatteries role as notebook computers and other portable devices optimized for endurance. Recent times, continuously be exposed laptop battery explosion, the laptop battery time and again pushed the cusp, the user has this lingering fear, lithium batteries in the end is a source of power or a bomb?

Find study battery fire mystery

In general, the current notebook lithium battery pack itself has a more complete protection.

It is not only from the string / multiple batteries in parallel composition, itself contains two kinds of circuit board modules: protection circuit substrate (Protection PCB) module and the Smart Battery Gauge Board module, its design includes a set of first-class battery protection protection IC (to prevent battery overcharge, over discharge, short circuit), the second-level protection IC (to prevent a second over-voltage), fuses, LED direction, temperature regulation and other components.

In a multi-level protection mechanism, even in the power charger, notebook computers unusual circumstances, the laptop battery can only be converted to automatic protection status, hp Pavilion dv2000 battery ， hp Pavilion dv6000 battery  if the situation is not serious, often still work after re-plug, not will be an explosion. Laptop battery exploded in the face of serious facts, the reporter sought the advice of professionals, as well as electro-chemical a well-known manufacturers of design engineers.

According to the analysis, lithium batteries is nothing less than an explosion caused by a short circuit or overcharge, the greatest likelihood of a lithium battery in the manufacturing, because of manufacturing process itself flawed, leaving the existence of product safety problems that may occur at any time, for example should be insulation between the poles of metal dust or a copper foil and aluminum foil pierced the membrane of the burr, resulting in micro-short circuits. The former situation is most serious, it will directly result in short-circuit, and a large number of heat production, resulting in vaporization of some of the electrolyte, the battery shell stretch.

In addition, there is a rather special case, the power charger or a laptop due to special reasons, the instant to the lithium batteries provide high-voltage / high current leading to a serious over-charge, such as the charging voltage from 12.6V sudden rise to 12.9V or even higher, when there will be a high charging current generation, the battery should be within the circuit moves to cut off charging current, but because part of the lithium battery charging over-voltage, over-current protection function design is weak, which may lead to the battery protection IC is damaged, so that to protect the laptop battery so that the function of damaged, over-charge on-chip over the posterior pole needle-shaped lithium metal crystal, piercing points, resulted in a number micro-short circuit, causing the battery temperature gradually increased, until eventually the battery explosion, fire phenomenon, This is currently a lot of laptop battery “hot” the main reason.

Add a layer of umbrella cover

At present, the battery protection mechanisms from the point of view, battery charging in front of some of the traditional chip vendors to play most of the programs are precise control of charging voltage and charging current role in the over-voltage and over-current control, and does not provide the corresponding solution.  hp Pavilion DV1000 battery ， hp Pavilion dv4000 batteryIn this way, the protection of the battery pack is entirely dependent on the battery itself, such as overcharge protection, over-discharge protection, over-charging current protection, over-discharge-current protection, over-temperature protection and so forth.

Protection in place need to prevent first-level protection IC failure or MOSFET short-circuit caused by over-voltage fault, so the second-level protection IC will generally be considered to protect the battery group last line of defense. In this regard, Bump E (O2 Micro) product manager for Hong Shi Zhen expressed different views, he believed that the protection for the battery pack can move forward, through the charger additional control functions, to achieve detection and control of battery charging action Undoubtedly, this will further enhance the level of protection, the protection of lithium batteries to use security.

To this end, in the O2 Micro power management for portable devices developed by Cool Charge solution which combines the one called Cool Battery Technology battery protection technology, and its most significant feature is to have a traditional chargers generally do not have the OVP (over Voltage Protection) and OCP (Over Current Protection) function of the two battery protection, this technology has been embedded among the Cool Charge IC chip.

After the adoption of Cool Charge IC chip, the power charger will largely assume the responsibility to protect the battery. Affected by the Cool Charge IC control, charger, compared with the traditional design (see Figure 1), the required external components significantly reduced, eliminating the need for Q3 and Q4 part of the design, reducing the failure rate. In the preserved Q1 and Q2 (components to improve the original design) between, Cool Charge IC set up a detection point, through the factory setting, the detection point voltage and current settings are slightly less than the battery http://www.battery-for-laptop.net/ manufacturers to set safety requirements. Thus, in the charge voltage or current exceeds the Cool Charge IC to set the security after the voltage or current value, IC on the control of Q2 off, first cut off before the battery charge protection; from detecting the frequency point of view, the detection time for battery protection ms interval level, through-chip detection, can be very easy to achieve millionth of a second level, you can use very high frequency of continuous detection, in order to achieve the first step to protect the battery pack purposes

vehicle powered by electronic

October 28th, 2009
Chinese auto makers are eager to enter the U.S. market, while BYD from achieving this goal may be one of the latest. However, BYD Automobile production may need to do Dell Inspiron 1520 battery  Dell Inspiron 1521 batteryfar more than a little adjustment. BYD by Buffett (Warren Buffett), a business partly owned.

A global automotive manufacturer’s technical director of a recent test drive of the BYD all-electric vehicles E6. He told the “Wall Street Journal,” says BYD plans later this year in China, the next year in the United States an immature market such a car, he was really shocked.

The executive said he was feeling rough from time to time test drive, which means that computer-controlled vehicle technology problems, the car control is not smooth.

BYD said the end of next year will begin to enter the United States, the introduction of BYD E6.

The company plans to first in the United States to select a particular area test in water, for government agencies, Dell Inspiron 1525 battery， Dell Inspiron 1526 battery utility companies and other corporate customers, “Hundreds of” E6 electric vehicles, each priced at slightly more than 40,000 U.S. dollars.

This is a risky move, because the battery-powered cars a key technology ─ ─ big storage capacity, energy and strong lithium-ion battery, the price is still too expensive, and related technologies are still considered immature. Toyota Motor Corporation (Toyota Motor Corp.) In 2008, had planned to use this technology, but then postponed at least two of the technology in the company’s products use. Toyota’s recent decision in the plan later this year in Japan and the United States introduced the use of plug-in hybrids lithium-ion batteries, but it is just a trial using this technology, because Toyota plans to introduce a small amount is only for the corporate clients of this plug-in car.

One big question is: a start-up companies such as BYD, its technology is not mature enough to introduce the quality and performance issues of lithium-ion battery-powered car?

Although as a lithium-ion battery and car manufacturer BYD may be leaps and bounds, but it is delivering on its promise in product launch track record is not how, and someDell Inspiron 5100 battery， Dell Inspiron 5150 battery industry observers suspicious, some minor technical issues may be plagued the company’s green cars. In addition to E6, the BYD’s green vehicles also include a charge called F3DM hybrid sedan.

BYD began late last year to sell F3DM cars for corporate clients, but since then has been unable to supply to customers, even though the company has said it plans in June this year, will be F3DM market.

BYD chairman Wang Chuanfu said, F3DM reason to defer to market because of BYD are waiting for the Chinese government has introduced to encourage the private Dell Inspiron 5100 battery， Dell Inspiron 5150 battery of “new energy vehicles” policy. He said that this price is about 150,000 yuan (about 22,000 U.S. dollars) plug-in hybrid car in China is too expensive for ordinary consumers and that the car need to be subsidized in order to sell out.

However, regardless of whether the Chinese government promulgated sales incentives, E6 electric car test drive experience, as well as the unavailability of the F3DM BYD cars supplied to the private clients this point, gave the company’s domestic and foreign clients to target the supply of branded cars E6 a question mark.

Battery with Cobalt & Nickel Material Recycling

October 27th, 2009

In the 863 field of new materials with the support of the Shenzhen High-Tech Green America Co., Ltd., Beijing University of Technology and other units through the production and sony VGP-BPS2 battery，sony VGP-BPS2A battery research co-operation, broke through the resource utilization of used batteries industrialization of key technologies, establishment of resource utilization of used batteries in the core patented technology system and standard system, the formation of annual recycling of used batteries and other waste, 20,000 tons of nickel cobalt annual output of high-performance cobalt, nickel metal powder production capacity of 2000 tons, and built a recycling technology to produce ultra-fine nickel, cobalt demonstration base powder materials.

Cobalt-nickel metal is widely used in batteries, carbide, stainless steel, petrochemicals, automobile manufacturing, machine tools, etc., cobalt and nickel powders are indispensable in modern industrial metal. China is a poor state of cobalt, cobalt resources of proven recoverable reserves are 40.9 thousand tons, accounting for only 1.03% of the world cobalt resources, while the cobalt resource consumption is 12,000 tons / year or more, accounting for 25% of the world’s consumption; Meanwhile, China is also a lack of resources of the state of nickel, has proven reserves of nickel resources of 232 million tons, accounting for 3.56% of the world, while China’s annual consumption of about 25 million tons, an annual shortfall of 10 million tons. China’s annual lithium ion, nickel metal hydride and nickel cadmium batteries more than 300,000 tons of waste, the amount of used batteries to retain more than 100 million tons of used batteries urgent need to develop resource utilization technologies. In the lithium ion, nickel metal hydride and nickel cadmium battery scrap, there is rich in cobalt, nickel metal, is an important renewable cobalt and nickel resources. The use of used batteries to produce high-end  VGP-BPS2C，VGP-BPS2Bproducts to meet the application requirements of cobalt, nickel powder, can form a virtuous circle of resource recycling.

Grammy Shenzhen Hi-tech Co., Ltd., New Materials Jingmen Grammy Co., Ltd., Beijing University of Technology, Central South University in cooperation for a typical multi-department of waste batteries and nickel-cobalt-waste recycling and high-performance nickel-cobalt-a study of new materials technology solve the performance restoration, revitalization and special structures forming, dismantling / classification, rapid separation and purification and other key technology and process equipment, build the failure to adapt to a variety of waste materials, cobalt and nickel recycling systems and new technology to build an area of 250,000 square meters of production base and research centers, to produce ultra-fine metallic nickel and cobalt powders, spherical nickel hydroxide, box-shaped cobalt oxide and the four spherical cobalt oxide sub-four series of nickel and cobalt powders, fully restored failure of nickel, cobalt material performance. Product cost less than the cost of the original minerals, product performance to meet the auto parts, precision machine tools and battery three different technical standards for the industry, access to national key new products and Hubei, Guangdong brand-name title, replacing some of the imported products has now met the  sony VGP-BPS5 battery，sony VGP-BPS5A battery carbide factory and part of the domestic battery industry’s needs, the annual output value reached 800 million yuan.

In the 863 Program and local governments with the support of the Grammy’s worked in Shenzhen, Hubei has established covering 20 cities, 7 million people of scrap battery recycling network, has assembled 15,000 waste battery recycling boxes, the annual recycling of 3,000 tons of used batteries above, the creation of a demonstration model of waste battery recycling. Green America with used batteries and other “urban mines” Resource Recycling, failure to achieve re-use of cobalt-nickel materials, product upgrades, forming independent intellectual property rights, building a cobalt and nickel metal circular economy industrial chain. This is to promote the development of China’s circular economy and ease China’s shortage of cobalt and nickel resources, reduce environmental pollution of great significance.

UPS is not a “battery backup”

October 21st, 2009
All along, UPS is the government procurement an important component of the data center, whether it is off-line, on-line or a range between the two interactive UPS, its status as a power source has neverdell battery wavered. However, the performance is perhaps the lack of visibility and intuitive, the data center’s “unsung heroes” in government procurement which has not been full recognition of the procurement people, the power is large enough to make even more errors on the application of government procurement UPS products have lost IT equipment, due to the protective effect, while the performance and configuration of the blind application of a variety of problems still plagued the procurement people.

With the government data center construction projects have gradually increased, UPS will become a popular product of the government procurement. However, UPS did not able to save the status in the procurement of human hearts, carefully look around the tender document for procurement of UPS products will find a lot of purchases of product performance parameters described in very general terms, but also a lack of UPS application environment and supporting facilities Dell Inspiron 1150 batteryin the Introduction. This undoubtedly indicates that the current UPS products, understanding of people there are still no small misunderstanding, but also for the government IT equipment to run conceals potential problems.

The lack of awareness of the UPS

Although the number of data centers along with other types of construction and procurement of IT products has a lot of demand, but whenever the issue of UPS products, many of the people are going to purchase it as a spare “battery” look.

Ji’an city procurement center in recent days UPS procurement project, called for procurement of UPS products, power 20KVA, but the measure of IT products of the most important technical indicators, the relevant requirements only power output capacity, rated output voltage, crest factor, rated input voltage 10 basic performance parameters, and limited the performance parameters of the procurement people are completely unable to reflect the actual needs of UPS. Journalists and a number of purchases were carried out on the UPS to communicate product performance and found a lot of procurement people UPS is also understood to remain in the Uninterruptible Power System (uninterruptible power supply system) in this literal sense.

In fact, UPS has already jumped out of a simple function of the uninterruptible power supply functions, the system also shoulder the IT systems more stable and reliable electricity, reduce electricity unusual problems caused by a variety of data anomalies to protect the information system the orderly operation of the function. Can be said that UPS now not just for IT equipment to provide electricity, but also become a high-quality power protection. In government, Dell Inspiron 1300 batteryhealth care, scientific research, aviation and other fields are often small changes in power supply system, or interference would be a substantial impact on information, the consequences are often disastrous, UPS as the “protection of God” also is self-evident importance.

a correct understanding of lead-acid battery repairment

October 20th, 2009
1, a correct understanding of lead-acid battery repair

Part of the failure of battery in a certain extent, you can use IBM ThinkPad R51 batterycertain methods and equipment repair, but not all failures of the battery can be repaired. Details please refer to open a repair errors electric vehicle batteries.

2, now lead-acid battery repair market, there is a certain confusion. Hope they will be careful to distinguish. Is not a device or a method you can repair any type of faulty battery.

3, several lead-acid battery repair hoax

100 years since the invention of lead-acid batteries, to excellent performance, low price firmly hold the big half of the secondary battery, is the world’s production of the largest and most widely used of a chemical power supply. Fatal weakness is the battery life is short, although its design life is 4-10 years, but the characteristics of its own led to its life is generally 1-2 years, to the user causing unnecessary economic losses, while increasing waste of resources and environmental pollution. Over the years, people of insight at home and abroad have made unremitting efforts to this end and exploration, and create a lot of effective repair method to extend battery life, battery repair a few years technology has gone through four generations, technology more sophisticated. In recent years, increasingly vigorous in the domestic market, the battery repair industry has gradually formed an immeasurably huge industry, and other emerging industries, there are always some malice in their hearts who, taking advantage of people in this emerging industry is not fully aware of the status quo, big Line pit Mongolia fraud in reality. Those deceived those complaints and verbal abuse never stopped and these people wanted to make a living to improve their living conditions, unexpectedly caught in the plight of the total loss   of confidence in this industry, so that more consumers become increasingly feel that this battery is a lie game imperceptibly into the battery to a subsequent repair of the practitioners more difficult.

There are several comprehensive view of fraud:

1, equipment, a high degree of intelligence do not need manual operation.

Most of such devices known as: repairing instrument connected to the battery positive and negative all the fixes that run automatically without human duty to repair after the automatic cut-off, without opening the cover, without adding any liquid, repair cost of zero. Even more amazing is that some devices also have a self-test function, according to battery capacity, internal resistance, damage model of the machine automatically determine the decision to repair mode and time.

The truth is: the majority of such equipment was “real charger, false instrument repair.” Pulse function with a small number of so-called “repair instrument,” having to charge the battery capacity can be upgraded, such as the user with a certain degree of repair knowledge, may be appropriate to extend the battery life; and a few devices have the function of detecting the battery internal resistance, saying that equipment have “test battery capacity, damage mode function” is sheer nonsense. Have the battery capacity test equipment, there is only a few foreign company and expensive, the yuan 4000-6000 yuan. Domestic battery capacity detection method, under the existing conditions can only be carried out constant-current discharge.

Battery repair instrument a high degree of intelligence does not mean that no manual operation, “intelligent” does not mean “fool” and like a fool cameras and digital cameras, both in effect, or method of operation could not be starker. If this industry is really as simple as a fool-oriented degree, it is recommended not to intervene: Even a fool can do something is bound to competition is very fierce.

Second, “good” is equal to the name of the high-tech

What are the negative pulse repair instrument; positive and negative pulse repair instrument; high-frequency pulse repair instrument; composite resonant pulse repair instrument; combination of pulse lead-acid battery repair instrument; swept pulse repair instrument; high-frequency combination, positive and negative pulse cycles Instrument Repair ; microcomputer combination of positive and negative ions negative ion scan pulse battery repair machines; FM high-power electronic pulses repair instrument; high-frequency low-frequency pulse + pulse + +-current to maintain high current to activate repair instrument; automatic frequency sweep resonance and synchronization of interference rejection techniques; lead-acid batteries Instrument Repair in recent years, emerging as a product, the state is no corresponding standard, the manufacturers in order to facilitate the marketing on their own to the device name, dazzling, true and false Nanbian.

In fact, now the repair battery repair and effective instrument are based on pulse technology, simply because the core technologies of various manufacturers who have not the same, using the pulse wave are not the same, we created a fixed battery results vary. The current lead-acid battery repair the main instrument to address the  IBM ThinkPad T40 battery phenomenon of sulfide battery, to break the shackles of the sulfate layer, it is necessary to enhance energy levels of atoms to a certain degree, this time in the outer layer of atoms increases with the electronic be activated until the next a higher energy band, so that atoms Unfettered. A particular level of each has a unique resonant frequency, must be provided to a number of energy can make molecules may be activated to migrate to a higher-level status too, too low to get the energy needs are unable to meet the energy requirements of the transition. Some repair instrument can meet this requirement, quickly remove the battery curing phenomenon; while others only in the so-called instrument repair process of using batteries used to charge the battery in order to delay the curing phenomenon. As for the so-called known as the most advanced, multi-resonant pulse restoration device, manufacturers play just a gimmick, all the pulse Repair Instrument in the repair process will generate a pulse wave generated harmonic resonance with the sulfuric acid lead salt, but are of different sizes only.

Even more bizarre is also known that his equipment is: intelligent power generation, universal emergency charger, battery repair MFP;

Is even more ridiculous is that he was also known as the equipment is: temperature curing instrument. Softening of the plate through the heat-curing repair the battery good.

For some manufacturers claimed that it is the first of several generations of instrument repair, we believe that: lead-acid battery repair techniques developed to date can be said that the fourth generation, as for the development of lead-acid battery repair instrument to the first generations of the reference, but also for too early.

3, the magic of the repairing effect

Repair time is short; can restore the original capacity of more than 90%; to extend battery life 3-5 years; is that many manufacturers advertising.

Some manufacturers claim that: General 12V (10-14AH) battery repair time is approximately 20-70 minutes ,17-22AH battery repair time is approximately 30-100 minutes. The actually more bold claims: Repair 10AH batteries in 10 minutes, fixed 20AH battery with 20 minutes.

Some claim that: For the plate curing, softening of the battery, single-cell micro-short-circuit damaged, or charging drum kit (also loaded into the battery box) of the battery repair rate of 90% or more (severe short-circuit and open circuit the battery can not be repaired), old batteries without the filter repair rate of up to 80%. Those who are more bold claims: can any waste batteries back from the dead; also declared: After repair, batteries not only restored the original nominal  IBM ThinkPad T41 batterycapacity, and has gone through professional instrumental analysis of the internal structure of the battery even further than the new science! Really: people more daring, to how much production.

The new battery production and recycling of used batteries is a very complex process, no matter how advanced the repair instrument called, are charging the battery, do not have other specific functions, saying that warming can be cured, repair plate softening, all is nonsense. Battery when the temperature rises in the repair, if no other heating and cooling equipment, along with the help of, the temperature will not rise, the temperature such as the rise of the equipment is a high-current charge, it will only damage to batteries. As we all know, the electric vehicle battery charging process, the temperatures are high will be filled drum battery. And good repair instrument repair the battery temperature will not rise.

As for the positive plate of the softening, because the positive plate active material lead dioxide during the process of electrochemical reaction to generate alpha and beta lead dioxide lead dioxide, these two components in the cathode plate similar to the tree and the tree leaves the relationship between the alpha lead dioxide is a branch, beta lead dioxide is a leaf, in the discharge process of Chiang Kai-shek and battery plate of lead dioxide in sulfuric acid to the electrochemical reaction to form lead sulfate, the charge has reduced to the process of lead dioxide, in the lead sulphate reduction process generates alpha and beta lead dioxide lead dioxide lead dioxide as the Beta gradual increase in the formation of plate softening. In the current existing conditions, can be melted down into lead powder to produce plates, and then create batteries.

Fourth, pull the banner, do tiger

(1), medals, certificates, a lot: What the international gold; National Top Ten battery repair instrument;  depending on the brands ranked; focus on promoting products; China  Center, China Association of  dual-control security system, security products; China  Inspection Association, full quality control products, China Association for Quality  test the credibility of security products; China product quality and protect the central focus of the promotion units; has passed the ISO9001-2000 international quality management system certification. And so on and so forth a number of dazzling, The true fictions of the so-called honor.

The truth is: lead-acid battery repair as an emerging industry (strictly speaking, known as the industry is still too early, because not yet formed an industry), has not yet attracted the concern and attention to relevant state departments, enterprises based on their hands related technology research and development of its own equipment, countries do not have the relevant product standards, how can this award certificates, said that the relevant national departments, such as some irresponsible and will not be issued to award no national standards. Only similar to the “National NCOH” so-called “China  Council (Center)”, in order to focus their economic interests and enterprises, a large number of awarded certificates, medals.

(2), strong technical force: The company’s gathered a group of professors from renowned institutions of higher education, experts, Dr.; from × × University and my company team of experts after many years of research and development; relying Provincial Academy of Sciences, the University and Automation Research The technical strength; company is located in a well-known or well-known institutions units or high-tech park.

At first glance, people have to believe that its technology is strong, in fact, many enterprises are in the “sugar daddy” syndrome, the office is located in the well-known units, its “worth” flew into double ugly duckling turned into a white swan , intentionally or unintentionally, the company announced strong technical force is also easy to believe. Home is located in a well-known universities in, known as “×-country technical, × large patent” company, customers purchased their equipment repaired the battery, put the excess liquid drained, after charge-discharge testing, the battery capacity dropped to King replied that their consultation: the active material had been drained. Even the actives do not know what that is, its level is obvious.

Repair lead-acid battery technology in China in the mid-nineties of the last century, due to constraints, equipment does not have the pulse function, repair, use of high-current battery-charging, over-charge, repeated charge-discharge, water cure and other methods to carry out, this Several repair methods only for curing the battery IBM ThinkPad R52 batteryto carry out minor repair, and the result is not satisfactory, did not receive further promotion, soon disappeared.

Pulse technology scrapped lead-acid batteries used in the study appear in the beginning of this century, this method for curing a serious effect more obvious the battery, because this method is still in the research stage, has not been practical application. Pulse lead-acid battery repair instrument to enter the market promotion, appeared in late 2003, is a company with Tsinghua University, Shandong, jointly developed by relevant experts. In 2004 appeared on the Internet and related information on the newspapers and magazines that have a fix for instrument repair solution is basically alone in this one, and only repaired solution (powder) but not fixed instrument, there are dozens.

Relevant information into the first half of 2005 gradually increased into the second half of 2005 Discerning fraudsters began beautifully, taking advantage of people lack of knowledge wantonly to defraud, two electric car charger and a car charger to sell competing pretending to fix Instrument 4,000 yuan. At this point the lead-acid battery repair technique-line information is not very rich, deceptive persons can not provide more lead-acid battery repair knowledge, built on the site, the information is not comprehensive, and very unprofessional.

2006 With the lead-acid battery repair technique on-line information-rich phase, the lead-acid battery manufacturers more and more fixed in the past, engaged in or engaged in this industry, one after another out of rivers and lakes, fishing in troubled waters, and more and more more. Most known for how many years engaged in this industry many years of history, many still claim to be “China’s × × first”, the website has more to build the more “professional”, deceptive stronger, so that the initial contact with the industry, newcomers, Nanbian authenticity.

How can I avoid being taken in entering the Walker

First, the right investment mentality.

At present, many people engaged in this industry have speculative mentality, coupled with Seeing with one eye, superstition in some factories so-called “automatic repair, auto stop, the repair process in the charge process automatically, without opening the cover, do not add any chemical , repair cost of zero. ” Want something for nothing, you can easily be Italian. Must know that “the sky is not Diaoxian Bing”, no one technology is not simply to the point.

The gullible persons, most of them had a “rich-quick” mentality, at the same time with “Chou Fu” mentality: they always want to invest little as possible to earn profits higher the better. Peacetime Yangaoshoudi, success is easy to see that someone “jealous”,听风is the rain, blind faith in false propaganda. That do not want to invest, do not want to do solid service, like riding, you can get rich, often fall into the trap of others; to say these people, “Chou Fu” mentality, what he said: Some people say that blind faith Instrument repair of low-cost, high price of equipment, manufacturers to reap the profits. Notice, repair, instrument although it has also to recharge the battery, but it has significant technical content in it, regardless of the cost or sales with the normal charger has a significant difference. Can say this: the high price may not necessarily be a good repair device, but the price is definitely lower ineffective instrument repair, and even that is a false instrument repair real charger.

According to authoritative statistics, with “rich-quick” mentality of the entrepreneur failure rate as high as 97.4%, and mostly end up being cheated. And successful entrepreneurs who started from scratch to a modicum of success, at least 1.5 years. Investors should be rational distinction between “rich-quick” and “wealth” will riches passionate desire to get rich as soon as possible realize their dreams of wealth.

Second, a better understanding of relevant knowledge

Do not be afraid to spend money, they should personally go to visit, if necessary, take the battery to verify the repair effects can not be right to go far away from the company visits, let him purchase of equipment, customer lists, phone calls, consult his equipment repair effect, multi-comparison that your knowledge can be rich in order to distinguish genuine, should not be fooled.

Available from the following aspects prove his technology (equipment) the authenticity of: (1), equipment, whether it is auto repair, auto stop, the repair process in the charge process automatically, without opening the cover. If it is, his device is a charger is no doubt that the real instrument can only be prompted to repair, will not automatically stop. Furthermore, the use of battery in the process will be short of water, add liquid without opening the cover, is a bad battery repair. (2), see the device output power (current) How much: small power equipment, repairing a long time, repair results are unsatisfactory. In the course of normal use the battery, use it to do maintenance charge can be extended battery life, right near the end of life battery repair, the result is not satisfactory; right equipment, the output power of large equipment, the repair process due to increase in current, such as the the battery temperature rise quickly, it is possible using a high-current charge. (3), lead-acid battery design life is 3-5 years, due to the use of the process easy to form sulfate, is often used to 1-2 years to scrap, repair, and then the use of 1-2 years, 40Y6797the effect is very good , and called after the repair can be re-used 3-5 years, regardless of their claim to be the most advanced rehabilitation equipment, and do not easily believe.

Third, do not be fooled by appearances.

Some companies incorporated less than a year dare to claim to be well-known trademarks in China patented product, there are a lot of companies that honor is true or otherwise, frivolous, “China’s first, industry-leading.” Whether the company is located in the well-known universities, or known as China’s first, both Do not take it seriously, multi-party inspection before making a decision, Mo-huang of the eye is superficial.

Two methods of solving the laptop batteries problem

October 19th, 2009

Most machines are all kinds of battery protection circuit, when the battery temperature is too high or when Dell Latitude X1 batterythe discharge current is too large, probably because the battery protection circuit moves beyond the standard, and thus causing the battery power automatically force the issue.

The most common situation is that the use of laptop computer battery is running at full speed when the current is too large to result in automatic protection. For example, from the drive to capture the contents of DVD discs into the mobile hard disk, when a large number of both host and peripheral power consumption, is likely to make current standards of protection beyond the battery, Dell XPS M1210 batteryin which case do not panic, as long as the Disconnect peripherals to wait about 10 minutes, you can reboot.

There is also a common situation is that laptop computers in a hot environment, high-load operation using the battery, so that the ambient temperature plus the heat generated by the battery self-discharge battery protection circuit may exceed the preset temperature, which is particularly high frequency P4 machines in high-temperature environment may occur after high-speed operation. Encountered such a situation should remove the batteries placed in a cooler place (remember not to put refrigerator frozen!), After half an hour shouldDell XPS M140 battery be back to normal. High temperature for the lithium battery damage is relatively large, less than a last resort and should be avoided in high-temperature environment, the use of high-load laptop.

In order to maintain the BIOS state, a lot of notebook computers that have the battery calibration option, simply speaking, this function will be the notebook’s battery is full and complete discharge to no electricity, and then re-filled, so for a long time not completely discharge the accumulated error caused by the role of a certain correction. However, please note the correction in the BIOS spent rather a long time, if you do this, preferably before going to sleep.

Many models also have Windows, discharge functions. This can save time, while working will be corrected. Battery Calibration will not be too frequent, often the depth  http://batterypt.blog.com/ of discharge is to bring the battery life shortened, it is recommended two to three months to do it once.

Could freezing method or the friction really extend handset battery life?

October 18th, 2009

More recently, so popular among all kinds of mobile phone batteries and “revived” the magic method, two of which are widely spread approach is the battery in the refrigerator “frozen” and the usehp Pavilion dv6000 battery  of rubber friction. However, these methods Emmanuel really do? Weikai specially invited journalists in Guangzhou Institute of Testing Technology Laboratory of experts for the battery. 
 
Identification 1: Frozen France 

“Folk secret”: 
1, the battery pack with newspaper before being placed in plastic bags, wrapping up well into the freezer for three days, newspapers can absorb excess moisture; 

2, three days after the decentralization of two days out at room temperature; 

3, two days after the battery charge, charge, yellow cell phone saturation test is estimated to save 80% ~ 90%. 

 Experts say: 

This report was groundless. General cell phone lithium-ion batteries in use in 2012, after the charge and discharge hundreds of times basic internal activity has been reduced chemical substances not normally a high efficiency charging and discharging. 

 As an argument is a simple temperature hp Pavilion DV1000 battery cycle test, the internal chemical substance can not be fully activated, the correct approach is to a professional recycling companies, decomposition to extract useful substances to prepare a new battery. 

 IB 2: rubber friction piece brass contact method 

 ”Folk secret”: 
Remove the battery after the battery with an eraser on the contact (brass piece) wipe clean, and then loaded back to the phone, the battery will be able to magic them back to life, but also as the new stars. 

Experts say: 

This approach can only be effective for some batteries. For certain lithium-ion battery is effective because the built-in shield reasons. Lithium-ion batteries are generally built-in protection board, limit its voltage range in a certain charge and discharge, when the voltage is abnormal (too high or too low), the action is triggered to cut off the power shield, rubber friction and the charging process which may promote the protection of board to recover, so the battery can work properly. In addition, the terminal does not rule out sometimes caused by bad contact above the dirt, when properly clean and maintain good conductive contact with the normal. 

Experts remind, and now the individual cottage hp Pavilion dv4000 battery battery protection board failed, can not be reset, or terminal contact conductive material difference in itself bad, or batteries quality problems, no matter how it is useless to use an eraser.

New Standard of Solar batteries

October 16th, 2009

Energy shortage and environmental pollution as the major issues affecting human development, known as the human inexhaustible solar energy, solar cell industry has grown in recent yearsDell Inspiron 6000 battery become the world’s important areas of economic development. However, in the rapid development process, the solar cell industry in the country, and there is no uniform industry standard, and there is over-investment, raw materials, waste of resources, excessive competition, even excess capacity and other issues.
How to use uniform standards to regulate the solar cell industry market? Yesterday, the solar cell standards Seminar in Guangdong Province, the first thin-film solar energy industry base in Sanshui held. The seminar was organized by China Electronics Standardization Association, the main, flat panel display industry in Guangdong Association, China National Building Material Group Corporation contractor. The Ministry of Industry and Information Technology, Guangdong Provincial Economic and Information Committee, China Electronic Standardization Technology Association and the National area of solar cells backbone enterprises, universities, research institutions, user groups, etc. More than 100 representatives attended the seminar.
The rapid development of solar cell industry
At present, the solar energy industry has become the United States, Europe, Japan, India and other countries an important direction of economic development. Particularly since the financial crisis, the rapid development of the industry is subject to the parties attention.
According to the Ministry of Industry and Information Technology Electronic Information Division inspector Wang Bo China introduced the world’s solar cell production increased from 1,700 Dell Inspiron 6400 batteryMW in 2005 to develop 6850 MW by 2008, in which thin-film solar cell output is 1100 megawatts, about 16%. Experts estimate that solar cell production in recent years will also maintain an average annual growth of more than 40%.
And the world echoed the development of solar cell industry, the last four or five years, China’s solar cell industry is also advancing rapidly, and has formed from the equipment manufacturing, raw material production, wafer preparation, the production of solar modules to the system installation, linking upstream and downstream of the entire industrial chain.
It is understood that polysilicon production in the mainland of China, from 2005 to 80 tons to 4715 tons last year, this year will exceed 15 thousand tons. Sustained annual growth rate of more than 100%. Accounting for the international market share in 2005 from 0.25% to last year’s 7.3%.
In solar cell production areas, from 145 MW in 2005 to the development of 2570 MW in 2008 continue to maintain the output of the world’s No. 1 status, sustained annual growth rate of more than 100%.
Overheated investment has emerged of theDell Inspiron 700m battery blind launched
“Solar cell and polysilicon industry, became one of the hottest industries.’s Domestic solar cell industry has entered the world’s most advanced industries, and its growth rate in the domestic industry’s fastest.” Wang Bo Chinese inspector view, multi-crystalline solar cells in particular, silicon industry, the overall warming, leading to overheated investment in some places, the blind launched such projects and so on.
It is optimistic about the development prospects of this industry, to varying degrees throughout the swarm on the project, giving rise to the State Council and relevant departments attach great importance.
“Solar cells so big a ship, if wrong, it is difficult to turn around the situation in this industry, very hot, the Government and industry should be how to lead?”
“At present, many enterprises in China are from foreign countries to buy the original piece of glass processing and sales market is also in foreign countries, forming a ‘two out’ pattern. In order to avoid becoming a simple solar energy emerging industries processing trade enterprises, do not take the original repetition of the introduction, repeated the old path of exports, reducing disorderly competition, vicious competition, a unified industry standard is imperative, “an international engineering company in building materials, Bengbu Glass Industry Design Institute, deputy secretary of Party Committee Ma Yun eager as soon as possible the formulation and implementation of solar cells industry standards, and will actively participate in the formulation of industry standards.
At present, the building materials in Sanshui in the establishment of a solar energy research and development centers, equipment manufacturing base and so on, “a self-developed technology and equipment, competitive, there is no excess.”
Organizations, standards bodies can set up in Guangdong?
At the meeting, Industry and Information Technology Han Jun, deputy director of the Department of Science and Technology Department and other participants on the formation of Chinese Electronics Standardization Association, under the national standardization of solar cells feasibility and necessity of the organization of work were discussed.
“Whether the standards will organize the work of thin-film solar based in Canton?” Guangdong Provincial Economic and Information Peng Ping, deputy director of the Committee at the proposal and the Guangdong solar cell industry chain base, is the industrial research, development, production, application an important Dell Latitude D820 batterybase for many businesses and a complete industrial chain can be a major force in solar Standards. ”
The participants believed that as soon as possible to the relevant standardization organization, give full play to the standard in the macro-control, industrial management, market discipline, application security, and other aspects of the core infrastructure role in promoting the sound development of China’s solar cells.
Link: thin-film solar energy industry base in Guangdong
Thin-film solar energy industry base in Guangdong Province is located in Sanshui, Foshan National Hi-tech District, the park planning area of 8 square kilometers, to take “a base, two partitions (producing regions and demonstration zones)” model of development, the formation of R & D, industrial production , personnel training all-round development pattern.
