The so-called correction, when the battery capacity and the actual control circuit record in a different capacity, to a depth of the laptop battery charge and discharge operation, control circuit record to make it close to the battery’s actual conditions, this is a true performance of the battery capacity The operation rather than enhance capacity, the key factor here is the actual capacity of the battery, if the battery capacity than the actual control circuit in the capacity to record high, the correction can increase the capacity of the battery looks, if the actual battery capacity than in the control circuit The capacity to record low, the correction will reduce the capacity of the battery looks, this is many people debate the reasons for the correction effects, keep in mind that the correction is the true battery capacity emerged, eliminating battery and control circuit between the Deviation, as to show the capacity will increase or decrease, this is the status of the battery itself rather than your correction by the decision. Correction is likely because the battery discharge when the depth of injury, but significantly decreased capacity.

Many battery manufacturers to provide a correction procedure, a Windows version and the version of the BIOS, the best use of these procedures to correction, Windows version can work side to side, BIOS version can not be this:

Laptop power much greater than the phone, the most extreme circumstances, the power need to charge the latitude battery and running at full speed machines to meet the required power supply, notebook computers generally not compatible charger, because the various models of voltage, current, or even Interface is different, to GM in a variety of notebook “compatible charger” very likely than the charger to your original, even if the interface is the same, if the voltage and current lower than the nominal value of the machines, machines working at full speed when the battery May not be able to obtain sufficient charge current, Latitude C840 battery on the damage is great. If the voltage and current much lower than the nominal value, or even find that simply can not start up or reboot it can not charge, so choose the power to choose the best time and put in the same, I can not find it, please note that certain voltage and current To comply with a nominal value of machinery, plant with the same general interface of different products, but may be different voltage and current, it must pay attention!
Mistakes 6: battery fully charged (or put photovoltaic) Save

Whether full or shine, in fact, are not correct, put long-term preservation of photoelectric Latitude C640 battery  will lose their activity and even lead to self-locking control circuit protection and no longer be able to use the full power will bring long-term preservation of the safety of hidden dangers, the most Save the ideal way is to discharge to about 40 percent and save, lithium batteries afraid of humid and high temperature, should be placed on a cool dry place preservation, but not too low temperature, or capacity will be greatly reduced, about 20 degrees Celsius around is the ideal Save temperature.

Currently on a global scale, the standard lithium laptop battery   are in a state of confusion, all countries and industries have some standards, but not the same, relatively authority of the two standards, one is JIS (Japan’s national standards), one is born In 2004 the “IEEE1625 (American Association of Electrical and Electronics Engineers mobile computer use rechargeable batteries IEEE1625 specifications).” In the field of worldwide laptop battery production, Japan’s Sanyo, Sony battery , Matsushita’s lithium batteries provide three of the world market share of around 70 percent, and Japan in the forefront of laptop battery standard, the United States because of possession of the notebook The world’s leading, and in the standard IBM battery on the legislative relatively perfect. Unfortunately, these two standards of the Sony failed to play its due role.

According to foreign media reports, this year in August, when Dell first announced the recall by Sony to provide the 4.1 million notebook batteries, Dell battery , Apple battery , Lenovo, and other electronic circuits and electronic industries Internet Association (IPC) of the OEM key components have been members of the Committee Decided that, in mid-September summit in San Jose, California, for the development of notebook computers and handheld electronic products of lithium-ion battery production standards. In their view, laptop battery manufacturers because of the participation of too much too high and battery manufacturers to consider the interests of the battery request is not high enough, thus leading to the recent frequency of the explosion of a laptop battery fires.

China’s laptop battery standard, it is almost empty. At present, China can be a constraint on lithium batteries, the  92P1101 battery is standard in the fourth part of the safety requirements of lithium batteries, but this is only the lithium battery of some of the basic safety requirements, and do not have a breakdown to specific products, notebook computers still use lithium batteries norms Is a blank.

“” Portable mobile computer power supply system common norms, “the end of this year is expected to be introduced.” Suzhou Fuyuan Technology Co., Ltd. General Manager Li Yunjie energy say for sure. Suzhou Fuyuan technology is one of the masters of the domestic laptop battery detection technology energy company, is authorized by the Ministry of Information Industry of China Hp battery  standard drafting the lead enterprises. April 2005, they and the National Information Technology Standardization Technical Committee with the initiative to convene a mobile power supply system (battery) standards seminar.

The birth of the notebook from that day onwards, the debate on the battery has never stopped, because of the use of persistent notebook is a very important technical indicators, and the laptop battery capacity of the notebook’s decision this important indicator. For technical reasons, the battery capacity will be affected by frequency of use, practical use and storage habits of various environmental factors, such as the impact of reduced or loss. In the end how can we maximize the use of a battery of the effect of extending the life of the battery? »
Many laptop users for the use of batteries also just stay in the initial stage, is how to protect the reasonable use of batteries and battery can not and will not know. Whenever these users complained vigorously to the use of battery time is too short or long battery life is not at the same time is not the first carefully from their peacetime use of the reasons for it找找» Of course, these two problems caused by the hp battery itself does not rule out the reasons for the quality of factors, but the vast majority of the current situation, man-made improper use of a very common situation.

Here are a few common errors, after a battery when we should pay attention! (That are not now the most commonly used for lithium-ion battery)

The first time the use of batteries, need to charge the three previous 12 hours »

This is totally not necessary. Because the notebook computers have improved power management circuits and charge management system, when the batteries reach saturation point, control circuit will automatically switch to the open circuit state, so even if the charge is no longer time to the role.

In order to prevent the memory effect, only to run out, charging it »

Every time before recharging the Pavilion DV4000 battery  discharge is not necessary and is harmful, because Practice has proved that the battery life of the depth of discharge will reduce unnecessary, when the proposal to use 10 percent of the battery can be charging at the. Of course, when the batteries are still more than 30 percent of the electricity or at best not to charge, because the memory effect really exists.

Insert AC, to the battery had to in order to prevent repeated charge and discharge it »

I will give you the proposal is: no. You may take the natural lithium-ion battery discharge to refute me, saying that if the battery discharge after natural power if repeated access will reduce the charge and discharge the battery life. I give you “no” answer to the following reasons:

1. Notebooks now have the power control circuit design of this: When thePresario V2000 battery  is 90% (such as HP’s most models) or 95 percent will be charged, and to achieve this through natural discharge capacity of the time for a thoughtful 2 , Now I will not said when the battery is idle for about a month to fully charge and discharge to maintain the capacity of the battery, this time you should be concerned about the battery should exercise the body and not be left idle after the re-charge;

2. Even if the battery “unfortunate” was once again charging, the loss will not be long without the battery than the decline in the number of electricity.

3. Your data than you or even your laptop batteries are much more rare, sudden power not only to your notebook harm, irreparable data is also too late to the regret.

Now the use of notebook computers are more and more, it has brought to the user to use the facilities so that we fully enjoy the mobile office by the fun. But if you thought, what is so convenient for laptops » In fact, it is the batteries, laptop batteries did not function in general and on the desktop there is no difference between the. At the same time inside the laptop battery is also expensive consumables, the longer the life of our use of the lower cost, we now use to talk about how to protect your battery.

(A) the need to activate the new battery 
In fact, the activation of work in the battery factory should have been completed, laptop battery factory with a small amount of electricity carried by the natural wear and tear in order to avoid damage to the battery. The battery should be activated in the absence of protection circuit of the circumstances, lithium hp battery itself with the protection circuit, the circuit design block purpose is to avoid over-charging and discharging of batteries, battery in a general, when the charging indicator light Out of that moment on, the battery is not in charge of the state, then this time you then plug into the charger to recharge the above is not any meaning. We can see that the battery on the situation in rechargeable batteries, there is a simple way to determine whether the battery charging status, the battery will be in charge of dissemination of a certain heat, when the battery is full after one hour (charger Not pulling the plug temporarily down), you touch the battery again, this time you will find that the battery is at room temperature in the state, this is because the battery charging status at this time has not, of course, there will be no heat produced.

(B) how to correctly charge 
Whether the use of laptop batteries or lithium nickel-hydrogen Pavilion DV4000 battery , these batteries are all the memory effect, nickel-hydrogen batteries have significant memory effect, lithium is also a memory effect, but its memory effect of the small number of nickel-hydrogen only. We have heard of the so-called lithium batteries that no memory effect, it is certain that JS exaggerated the purpose of the guide is wrong consumers. Since the lithium battery of memory effect, then in charge when power should be used to recharge, Do not want to go when the charge went charging, although used to facilitate this, but will shorten battery life. However, we do not need to go, and so on, completely used up charge, so too much trouble. Although such as a battery protection circuit will not be under the protection will not damage the battery, but not particularly necessary. In fact, in less than three percent of electricity when you can charge, the memory effect is an objective reality, but compared to the natural wear and tear, has not had any.

(C) use an external power supply when the need to pull out the Presario V2000 battery 
In fact, this depends on your time in the use of an external power supply is not required to charge the battery, battery charge directly related to the number of life, under normal circumstances lithium battery charging and discharging a fixed number, number of charge cycles generally only about 500 times the maximum Does not exceed 800. Each of us to charge a battery, and correspondingly, the first of which could also reduce the number of charge cycles. But now many notebook manufacturers are taking into account the vulnerability of the batteries, increasing the battery-protection technology, does not meet certain conditions will not be charged. Even so, a long time when you use an external power or the use of computers is recommended that you pull out the battery, because the high temperature is the nemesis of the battery, when used in notebook computers will have a certain temperature, the battery is very harmful. Of course, if you’re not sure their batteries, then I encourage you to the pulling down your ThinkPad X60 battery  re-use an external power supply, because not all have to protect the battery circuit.

     Bosch (Bosch) and Samsung SDI (Samsung SDI) holding 50 percent stake in the joint venture SB LiMotive Co. Ltd. On September 1, 2008 put into operation. The two sides set up this new company to develop, manufacture and marketing of automotive applications for the lithium ion battery. The company plans to start mass production for automotive demand for efficient lithium-ion battery  system and in 2011 the global market. To achieve this goal, a joint venture the two sides will in the next five years investment from 3 to 400 million U.S. dollars. Youngwoo Park (Samsung SDI) and Dr. Joachim Fetzer (Bosch) will jointly lead the new company, Park will be responsible for finance, production, marketing and procurement work, and Dr. Fetzer will be responsible for engineering and quality work. A few days ago, Bosch and Samsung SDI access to all relevant departments to form the joint venture’s approval.

SB LiMotive headquartered in Hanguoshuiyuan, the first battery pack will also be developed. Subsequently, in South Korea also plans to launch lithium-ion battery production. About 100 employees will work here. In addition, in Stuttgart, Germany, the establishment of a subsidiary. Initially, there will be 40 employees in sales, promotion and systems engineering work . Hp battery  system will be announced the specific location of production sites.

Batteries of any part of the solid material from the moment, was pushed from the battery to 25 cm over the distance, called the explosion. Determine whether or not the laptop battery explosion, the following conditions experiment. Will be a net Zhaozhu experimental battery, battery living in the center, away from any side for the network covers 25 cm. Net density of 6-7 root / cm, cable diameter of 0.25 mm using the soft aluminum, if the experiment with some solid through the net enclosures, that the battery is not an explosion.
Li-ion battery problem series

As the battery in the production process, from beginning to become a finished film to go through many procedures. Even after rigorous testing procedures so that each power supply voltage, resistance, capacity, but the use of a period of time, will also have this or that difference. As a mother of twins of Health, recently gave birth may look the same, as a mother is hard to tell. However, the two children continue to grow, it will produce this or that the difference lithium latitude battery as well. The use of a difference after a period of time, the overall voltage control by the way is difficult to apply to the lithium battery, such as a 36 V of the cell stack, we must use 10 batteries in series. The overall charge control voltage is 42 V, and the discharge control voltage is 26 V. With the overall voltage control, the initial stage because of the use of battery consistency particularly good, perhaps there will not be any problem. After a period of time in the use of battery internal resistance and voltage fluctuations have formed an inconsistent state, (is not absolute, consistency is relative) are still using this time the overall voltage control is not achieved its objectives. For example, 10 of which two battery discharge when the battery voltage 2.8 V, four battery voltage is 3.2 V, only four 3.4 V, now the overall voltage is 32 V, we let it continue to discharge has been working to 26 V. In this way, the two batteries on the 2.8 V below the 2.6 V in the off-state. Lithium battery is equivalent to several times the release scrapped. Instead, with overall charge voltage control the form of charge, there were also filling the position. For example, the above 10 at the time of the battery voltage state of charge. Overall voltage 42 V, the two batteries in the 2.8 V \ “hunger \” state, the rapid absorption capacity, it will超过4.2 V, and a charge of more than 4.2 V Latitude D800 battery , not only because of a high voltage scrapped Or even dangerous, and this is the characteristics of lithium battery.

Lithium-ion battery rated at 3.6 V (some products for the 3.7 V). When fully charged and the termination charge voltage of the battery anode materials: graphite anode materials for the 4.2 V; anode materials for Coke’s 4.1 V. Anode different materials have different internal resistance, the resistance of the anode coke slightly larger, the discharge of slightly different, as shown in Figure 1. Commonly referred to as the 4.1 V lithium-ion battery and 4.2 V lithium-ion battery. Is now used by most of the 4.2 V, lithium-ion Latitude CPi battery  discharge voltage for the termination of the 2.5 V ~ 2.75V (battery factory is operating voltage range is given to terminate or discharge voltage, a slightly different parameters). Than to terminate the discharge voltage discharge known as a put, the batteries will be put on the damage.

Portable electronic products to the battery as a power source. With the rapid development of portable products, increased consumption of all kinds of batteries, and developed many new battery. In addition to all of the more familiar high-performance alkaline batteries, rechargeable nickel-cadmium batteries, nickel-hydrogen batteries, but also in the development of lithium batteries. In this paper, on the basic knowledge of lithium Latitude CPX battery . This includes the characteristics of the main parameters of the model significance, the scope of application and use of attention to matters.

Non-rechargeable lithium batteries There are many, are commonly used lithium - manganese dioxide batteries, lithium - thionyl chloride batteries and lithium batteries and other compounds. This paper introduced the first two in only the most commonly used.
1, lithium - manganese dioxide laptop battery (Li  MnO2)
Lithium - manganese dioxide battery is a lithium to the anode, manganese dioxide as cathode, and the one-time use of organic electrolyte batteries. The main characteristics of the battery cell voltage is high, rated voltage of 3 V (alkaline batteries are generally two times); termination voltage discharge for 2 V; than the energy (see the example cited above); discharge voltage stability and reliability; better The storage performance (save time for more than three years), low self-discharge rate (the self-discharge rate of ≤ 2%); working temperature range of -20 ℃ ~ +60 ℃.

The latitude battery can be made into a different shape to meet different requirements, it is rectangular, and the cylindrical-shaped button (button). Cylindrical have different size in diameter and height. Here are just more familiar with all the 1 # (size code D), 2 # (size code C) and 5 # (size code AA) batteries of the main parameters.

CR said that for cylindrical lithium - manganese dioxide battery; five figures, said the two previous Latitude D800 battery  in diameter, said after the three with a few high. For example, CR14505, its diameter of 14 mm, height of 50  5 mm (this model is common).

Here like to point out that factory production is different from the same type of battery may be some differences in their parameters. In addition, the standard discharge current value is smaller, the actual discharge current can be greater than the standard discharge current and continuous discharge and pulse discharge permit discharge current is also different from the battery company to provide relevant data. For example, the power-supply company is the largest CR14505 continuous discharge current for 1000 mA, the largest pulse discharge current up to 2500 mA.

Camera used most of the lithium Latitude CPi battery  is lithium - manganese dioxide battery. Here’s camera frequently used in lithium - manganese dioxide battery included in Table 2 for information.

Button-style (button) smaller battery size, a diameter of 12.5 ~ 24.5 mm, height of 1.6 ~ 5.0 mm. Several more commonly used button cell As shown in Table 3.

CR for cylindrical lithium - manganese dioxide battery, after the four figures in the two previous size of the diameter of the battery, after two of the decimal point with a high degree of size. For example, CR1220 has a diameter of 12.5 mm (not including the number of decimal places), its height is 2.0 mm. This model that is internationally used.

This button cell commonly used in the clock, calculator, electronic notebook, cameras, hearing aids, electronic games, IC cards, backup power supplies.

2, lithium - thionyl chloride Latitude CPX battery  (Li  SOCl2)

Lithium - thionyl chloride battery is one of the highest energy density, up to 500 Wh / kg or 1000 Wh / L level. It’s rated voltage is 3.6 V, to the middle when the current discharge is extremely smooth discharge of the 3.4 V (at 90 percent capacity to discharge within the flat, do not keep the change). Battery can -40 ℃ ~ +85 ℃ within the scope of work, but in the capacity of -40 ℃ at room temperature about 50 percent of capacity. Low self-discharge rate (the self-discharge rate of ≤ 1%), storage life for over 10 years.

1 # (size code D) nickel-cadmium batteries and lithium-# 1 - thionyl chloride battery than the energy to make a comparison: 1 # nickel-cadmium Latitude C600 battery  is rated voltage of 1.2 V, up to 5000 mAh; 1 # lithium - thionyl Chloride rated voltage of 3.6 V, a capacity of 10000 mAh, while the latter than the former six times the energy!

   BYD shares (01,211), the Group’s future balanced development of cars, two rechargeable battery and cell phone parts and assembly of the three major business, is expected to annual capital expenditure of 50 billion yuan (RMB, the same below), of which 20 for the second half Billion, mainly for plant construction and upgrading of the three major business productivity.

Wang Chuanfu president of BYD shares yesterday at a press conference performance, lithium Asus battery   have a steady growth in orders, an increase of about 20 to 30 percent, but the orders of nickel batteries have a slight decrease in the same period last year, but still the cost of mobile phone business Faced with pressure, as for automotive operations will continue to grow rapidly. She refers to, Qijuchanneng next year will be 20 million units this year to 400,000 units. As the Government to support the development of the automotive industry, the Group received 136 million yuan in the first half of government subsidies, the Group believes that in the next five years will continue to receive subsidies.

By phone components and modules business gross margin declined, as well as lower gross margins accounted assembly services increased impact of its BYD Electronics (F2299A) in the first half gross margin from the same period last year fell 34 percent to 19 percent, BYD Electronic Co-Secretary Li Qian said that with the Group’s business expansion, as a whole, gross margins can be expected to maintain the current level. He refers to the current group of assembly services and mobile phone components and modules business gross margin, respectively, higher than the industry of 4-6 percent and 25-30 percent level. But Wang Chuanfu think that the overall gross profit margin fell, but sales continued to grow, the business model does not change much.

The electricity demand growth in the past few years a number of times. End-user requirements to provide maximum laptop battery power, and increasingly long working hours. In mobile phones, notebook computers, digital cameras, cordless industrial equipment, backup power, military and medical applications such as the market in the technology market changes very rapidly. Batteries need to keep up with their speed of change to meet the growing for the safety, reliable and continuous power supply needs. This is to promote the development of battery technology industry the main driving force.

Market research firm Frost & Sullivan that the 2005 global emerging market sales of batteries 1 billion U.S. dollars. The company also estimated that as consumer electronics, industrial equipment, backup power supply and other vertical markets growth in demand, the sales growth will more than double. “Today the desire for power the next generation of electronic devices require batteries provide longer hours of work, while maintaining a lighter weight and smaller form factor.” Frost & Sullivan, director of research Sara Bradford said. “Although the market in pavilion battery technology to meet the general needs, but soon encountered a longer working hours for the request. In addition, many industrial applications require stronger and more secure power supply system.”

Battery market is fast approaching maturity and continuous research and development activities for the demand and sales revenue to maintain the stability necessary. Moreover, the battery market is also fierce competition in the efforts to stimulate the manufacturers in the F2019  market in the realization of the difference, or launch
New technology. Market participants in the study fuel cells, flywheels and super-capacitors and other types of power, they may be better than the traditional battery technology of choice. However, these new battery not likely in 2010 before entering the commercial market.

The raw materials are any restrictions that may ultimately affect the emerging battery market. The need for new suppliers, because the existing requirements of suppliers of raw materials and components to expand production to meet the emerging market for the growing expectations of the F2019B .
