Recently, Linear Technology has introduced a highly integrated, multi-chip battery monitor LTC6802. This chip can be measured 12 separate hp dp390a battery , volume production is expected by the end of this year.

Due to resource constraints and increased environmental pollution, China has strongly supported the development of new energy vehicles. In the development of new  ibm 92p1077 battery energy vehicles, battery research and development has been the bottleneck. In recent years, lithium-ion batteries with excellent energy density has become the first choice for new energy vehicles. But lithium-ion batteries for over-charging or excessive discharge very sensitive to the needs of the battery pack in each cell to carry out prudent management. Linear Technology has introduced the new multi-cell chip can monitor each battery for fast, accurate measurements for the use of lithium-ion batteries to provide strong protection

Yesterday, a Dell notebook batteries exploded burning pictures on the network has been widely reproduced, said the incident was posted on September 3 took place in an office in Shanghai office. Dell China, a spokesman said yesterday that the explosion of notebook batteries last fall because of fire danger recalled models. 916-2150 , CGR-B1870AE , DD880A , DM842A , DP390A , DP399A , EF419A , EV087AA

Notebook flames leapt up from 10 cm

To drive users to upload home photos of the site revealed that on September 3 in the afternoon 13:52 Xu, a table placed in the office of a laptop suddenly caught fire, jumped out of the flames about 10 centimeters, the notebook can be Clearly see the “DELL” trademark. EV088AA , EX942AA , F1466A , F1739A , F2019 , F2019A , F2019B , F2024A , F3172A , F4098A

After that, this notebook’s battery is almost completely burned down parts of deformation, the keyboard on a shaman of the yellow powder. Friends said the explosion was burning notebook models D600. Yesterday, a spokesman for Dell China, said that this explosion of the burning Dell notebook battery recall last year have been issued a notice of the models for this event, Dell will work with the client consultation.

Battery recall has caught fire danger

Last August, Dell announced the headquarters of a global recall of about 4,100,000 “Fire” battery, which is also the consumer electronics industry, the largest in the history of a recall. The recalled battery sales for the period April 1, 2004 to July 18, 2006 by Sony manufacture, involving a range of 20 Dell computer models. F4486A , F4486B , F4809A , F4812A , HSTNN-DB02 , HSTNN-IB04 , HSTNN-LB31 , HSTNN-UB02

These batteries in particular the extreme conditions, as the batteries in some of the core metal particles exist, batteries overheating and even fire risk will increase. Prior to that, Dell notebook batteries due to similar problems occurred in the United States 6 of the accident. Post reporter noted that, D600 did in last year’s recall.

Dell China, a spokesman said yesterday, for the purchase of the recalled batteries to customers, Dell has been requested to inform, but some customers have not been able to contact, “Dell hopes users log on www.dellbatteryprogram.com query whether the recall of batteries Out. “PB991A , PB992A , PB994A , PB995A , PF723A , PP2182D , PP2182L

So that all notebook battery manufacturers and notebook makers storm into the recall of lithium-ion batteries, allowing these companies in the new year into a tort crisis.

Yesterday, Minnesota Mining and Manufacturing Co. (3M Company) announced that it has submitted to the Court of the United States related to the indictment, charged with a number of laptop manufacturers of lithium batteries, as well as notebook manufacturers a violation of its lithium battery patent. The defendants, including Japan’s Sony, Panasonic, Lenovo China, including a number of well-known enterprises.

3M said the company has at the same time called on the United States International Trade Commission ban on imports of the allegedly infringing use of lithium and lithium batteries for laptop batteries. However, 3M did not disclose whether the company suspected that these companies as well as the amount of compensation payments. Armada E500 , Armada M700 , Business Notebook nc6000 , Business Notebook nc8000 , business notebook NX9000 , business notebook NX9005 , business notebook NX9010 , EVO N100

The key: battery materials infringement

The infringement case is the focus of an internal lithium battery cathode material. 3M said the material in the world there are about 700,000,000 U.S. dollars of the market. The company stressed that because of their invention in the use of such materials, making lithium battery life is not easy, as well as the extension of overheating.

Lithium batteries because of overheating problems exist, such as Sony laptop battery manufacturer in the last year, had a massive notebook battery recall. And Sony is to pay for the recall of 4.4 million, the company recalled a total of 9,600,000 notebook lithium batteries, becoming the largest consumer electronics in the history of a recall. PP2100 , PP2200 , Presario 1200 , Presario 1500 , Presario 1600 , Presario 1700 , Presario 1800 , Presario 2100

The plaintiff: The technology is not easy

“It took us 10 years to study the development of lithium battery technology.” 3M Company spokesman Alexander Downer said next Friedkin, “12 months ago, before we have the technology for commercial means.”

Friedkin stressed: “For us, accession to the technology products also promote the stage, we have this technology investment, plans to use the technology of the global lithium battery production.”

According to the 3M Company in 2005 with the publication of the patent in 2006, the company has been conducting technical salt used in lithium batteries, adding that the electrical conductivity of salt to improve the durability and safety of the battery, little overheated. Presario 2500 , Presario 2800 , Presario 700 , Presario 900 , Presario M2000 , Presario X6000 , Presario R3000 , Presario V2000 , Presario V4000 , Presario V5000

The defendant: It is not clear the matter

3M Company in the indictment made special mention of the Sony. The company said that Sony and its notebook lithium battery manufacturing subsidiary, Sony Electronics without a 3M company agreed to use the technology.

At the same time, U.S. manufacturers of lithium batteries CDW Corporation and Total Micro Technologies, 3M Company has also been accused of using the technology. The two companies produce lithium batteries are used in Lenovo Thinkpad notebooks; Dell for the manufacture of batteries Batteries Com also listed as defendants, but Dell does not appear on the list of defendants. In addition, Japan’s Hitachi and Matsushita own products used in the alleged infringement of lithium batteries, has also been involved as a defendant. 342661-001 , 346970-001 , 361742-001 , 367759-001 , 371785-001 , 371786-001 , 372772-001 , 398876-001

Yesterday, the reporter with the plaintiff 3M China’s public relations contact after that, China also is not clear the prosecution; and Lenovo, Panasonic China also told reporters that the Chinese side has not yet been informed about the case; Sony China The company said that the prosecution case had been heard, are due to contact with the headquarters, is not convenient to give any comments

Now that cell phone use lithium-ion battery, so there is no memory effect problem, do not need to activate the first rechargeable nickel does not need electricity as red as more than 12 hours, filling only about 4 hours, ion battery life with the only charge Related to the number of lithium-ion batteries can be recharged 1,000 times or so. And the use of standby time related. However, sales of mobile phones said that three times in front of charging time to reach 12 hours. How in the end matter?
1, for a new apple A1060 battery charge
In the use of lithium batteries should be noted that for a period of time after the battery is placed into hibernation, lower than normal capacity at this time, the time has also come to shorten. But the very capacity lithium batteries
Easy to activate, as long as after 3-5 times the normal charge-discharge cycle of the battery can be activated, the resumption of normal capacity. As the battery lithium own characteristics, its decision is almost no memory effect.
Therefore, cell phone users in a new lithium battery in the activation process does not require special methods and equipment. Not only is the theory that, from my own practice, from the beginning to adopt
Using the standard method of charging that “activation” is the best way.
Lithium batteries for the “activation”, a large number of claims: the time to charge more than 12 hours, repeated three times to do in order to activate the battery. “The first three necessary and sufficient to charge
More than 12 hours “, it is obvious from the nickel apple M8511 battery  (such as nickel-cadmium and nickel metal hydride) inherited. This is why it can be said is the beginning of miscommunication. Lithium batteries and nickel batteries
The charge-discharge characteristics of a very big difference, but also very clear to tell you that I have had access to all the serious official stressed that all technical information and charge-off will discharge lithium power
Chi, in particular liquid lithium-ion battery causing great harm. According to the charge and therefore the best time and method of charging standards, in particular for not more than 12 hours of super-long charge
. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of charging.
In addition, the lithium battery in the phone or battery charger will automatically stop after a charge, there is no electricity nickel charger for 10 hours the so-called “trickle” charge. In other words
If your lithium batteries in full, on the white charger is also sufficient. And we can not guarantee that no one battery charge and discharge protection circuit features and never change the quality of perfect
Therefore, your apple PowerBook G4 battery  will be in a long time hovering on the brink of danger. This is also another charge against the chief reason.
In addition to certain mobile phones, the charge for more than a certain amount of time, if not remove the charger, this time not only to stop charging system, will be the beginning of discharge - charge cycle. Maybe
This is the manufacturer of its own end, it is clear that on the phone and battery / charger is the life span of a negative. At the same time, long charging would take a long time, often at night,
China’s power grid and to look at the situation in many places higher than the voltage of the night, but volatile. Said earlier, the lithium battery is very delicate than nickel in the electric charge and discharge aspects of resistance
Fluctuations in the capacity is much less, so this brings additional risk.
In addition, can not be ignored other aspects of a lithium battery that is not the same for over-discharge, over-discharge of lithium batteries is also very unfavorable. This leads to the following question.
2, in normal use when the charge should be
In our forums, often see this as the number of charging and discharging is limited, so should the cell phone battery power used up as much as possible and then charge. But I find
With regard to a lithium-ion battery charge and discharge cycle test table, on the life cycle of figures is as follows:
Life cycle (10% DOD):> 1000 times
Life cycle (100% DOD):> 200 times
DOD is the depth of the discharge of which the initials. Can be seen from the table, the number of rechargeable and about the depth of discharge, 10% DOD at the time of the life cycle than 100% DOD’s a lot longer. Of course
If the actual charge equivalent to the total capacity of the relative: 10% * 1000% * 100,100 = 200 = 200, which is the complete charge and discharge, or better than some, but in front of the users have to say that
Some amendments: Under normal circumstances, you should have a reservation in accordance with the remaining battery power and then run out of filling the principle of charging, but if your asus A42-A3 battery   is expected in the first 2 days you can not insist on the whole
During the day, should start on time charge, of course, if you are willing to carry another charger to the office when Bielun.
And you need to charge in order to cope with the anticipated upcoming busy communications will lead to an important event, even if there are a lot of battery power over time, then you just charge ahead,
Because you do not have a real loss “1″ sub-charge cycle life, that is, “0.x” times, but often this will be a very small x.
The remaining battery power and then run out of charge to the principle does not mean that you go to the extreme. And charging the same length of a widespread view that “as far as possible the cell phone batteries run out of power,
Best used in automatic shutdown. “This is just a matter of fact on nickel batteries, to avoid occurrence of memory effect, unfortunately, it is also spread of lithium batteries on this. There
Because of low cell phone battery warning appears, do not continue to use the charge has been used in automatic shutdown of the case. The outcome of this case, the phone was in charge and in the boot
There was no response, had to give customer service overhaul. In fact, this is due to the battery as a result of excessive discharge and led to the low voltage that does not have the normal charge of the boot and conditions.
3, Li-ion battery for mobile phones in the right way
To sum up, I lithium batteries used in mobile phone charging and discharging of the most important tips are:
1, in accordance with the standards and procedures, charging time, even before the three to do so;
2, When the phone prompts when electricity is too low and should start charging as much as possible in a timely manner;
3, lithium batteries do not need to activate the special method, in a normal cell phone use in lithium batteries would be natural to activate. If you insist on spreading the use of “three times before the 12-hour long activation charge”
Methods In fact, the effect will not be.
As a result, all 12 hours long pursuit of the lithium batteries and rechargeable cell phone used in automatic shutdown, are wrong. If you are used to be in accordance with the wrong done,
Please correct in a timely manner, perhaps not too late.
Of course, cell phones and chargers to protect themselves and control the quality of a good circuit, for the protection of lithium dell 1691P battery  or have guaranteed. Therefore, understanding the rules of the charge is the key, in some cases also may make some concessions. For example, you found your cell phone the night before bed charge, you can also start charging before going to bed. The crux of the matter is that you should know what is the right thing to do, and not in accordance with the deliberately wrong to do.

According to foreign media reports, LG Electronics announced Tuesday the company will be abandoned in the plasma display panel factory building two solar cell production line. This initiative shows that LG Electronics in the hope that the renewable energy sector to seek a new growth point.

LG Electronics in June bought LG Chemical’s solar sector. LG Electronics said it will invest 222,000,000,000 won (168,000,000 U.S. dollars) to build two production lines of solar cells. This will be two production lines in early 2010 and start mass production early in 2011.

LG said in a statement, the two production lines to produce crystalline silicon solar cells and modules, the production capacity of 120MW.

LG Electronics is a manufacturer of home appliances and mobile phones. As the prices of TV, LCD TV, as well as from the increasing competition, the company closed in 2007, three plasma displays (PDP) in a factory.

At present, notebook computers commonly used lithium-ion battery (included businessmen say the high-performance lithium battery, intelligent and efficient lithium battery, etc.), the mainstream P4-M notebooks of standby time in general about 2.5 to 3 hours, the dell Latitude D500 battery capacity of about 4500mAh, even if it is based on The latest Centrino technology for notebook computers generally can only reach about 4 hours of the time, it can not reach a lot of demand for Mobile users.

In order to enhance the capacity of battery life, manufacturers have been active in the efforts that we have no way to improve the life of the battery capacity? The answer is: Yes, we put it to sum up: the ability to upgrade the battery life of the Fifth Discipline, the following one for you A presentation.

  The use of batteries and maintenance

Notebook computer batteries is the key to the standby time. To enhance the capacity of endurance, focus on essential maintenance of the battery.

1. In the use of laptop computers to read carefully before using the maintenance part of the battery manual; 2. Charger for the first time, you should continuously charge the battery to 12 hours, and to completely Circulating charge, 3 discharges in order to complete the new wake-up battery; 3. If you use an external power supply for a long time, it is best to remove the battery. Many people have asked me not aware of this issue, with an external power supply when the battery is not removed not only affect the battery life of notebook computers also allow the heat to become even heavier burden to shorten the life of notebook computers; 4. Charging and discharging on a regular basis. Even without the memory effect of lithium-ion battery There is a certain inertia effect for a long time not to lose the use of lithium-ion activity will require re-activation. Therefore, if not for a long time to use a computer or the dell Latitude D600 battery  charge and discharge found that shorter time, the batteries should be fully discharged before charging, in general, at least a month to complete charge and discharge 1. 5. Recharging the best time to switch off the laptop, so that the battery can be completely full of electricity, not to charge out half-way power. Will start charging off than the charge to reduce the charge for more than 30% of the time, but also to extend battery life. The best in charge after 30 minutes before use. 6. To prevent exposure to prevent damp to prevent the erosion of liquid chemicals, batteries to avoid contact with metal objects, such as access to short-circuit occurred in the situation from happening.

 
Lithium battery charge and discharge less than the number 800, on one charge, it will shorten the life span of time. We proposed to make full use of external power supply, if the need for the use of many half-way Plug Power, and built-in laptop batteries have not pulled out, the battery will Zheshou great, because every time an external power supply on access to the equivalent of dell Latitude D620 battery  time. For notebook users, we recommend the use of WindowsXP operating system, of course, if the laptop configuration is too low and even WindowsXP can not meet the minimum configuration requirements, it would be a different matter. There are many reasons, the main point is that the notebook computer power management is all-the-art computer operating system, if the Centrino platform, coupled with so much the better. 1.6GHz of the Pentium-M smaller load of work only in the following frequency of 600MHz.

If your notebook computer to support the Intel SpeedStep, AMD PowerNow  or Transmeta’s LongRun technology, we must keep in mind fitted with the latest driver to play its biggest utility, WindowsXP is automatic, you can own in accordance with the requirements of performance and Power to find a balance.

A few days ago, in Japan, Makuhari International Convention and Exhibition Center at the CEATEC JAPAN 2008 exhibition on TDK and Murata Manufacturing ESR are used to control the display of laminated ceramic capacitors, laminated ceramic capacitor will be the equivalent series resistance (ESR) is set to The higher the value, can suppress the power | Regulators | Regulators / ground level noise caused by electromagnetic radiation, which control the ESR has begun gradually recognized. Their ceramic capacitors have been the beginning of such samples available, sony PCGA-BP71 battery plans to mass production starting in 2009.

ESR control system was in January 2007 in the United States held “DesingCon 2007″ by the United States put forward by Sun Microsystems technology. Under normal circumstances, the stratification of the dell d5561 battery  ceramic capacitors and the equivalent series inductance (ESL) the lower the better. However, Sun said that if the lower ESR, impedance frequency characteristics of the show will be too prominent resonance (Q value is too high) so that the anti-resonance point of the high-impedance changes. This will cause high-frequency electromagnetic radiation to enhance the noise. As a result, by ESR set to a higher value to reduce the Q value, thereby reducing the resonance point and a half of resistance, can suppress high-frequency electromagnetic radiation noise. dell inspiron 9300 battery battery

Murata Manufacturing of the show trial of its products is characterized by the electrode set up in the long side of the low-ESL products used in the ESR control. ESL value varies by product, but only at 100p ~ 150pH. Size for 1.6mm × 0.8mm × 0.5mm, for the voltage 4V. May ESR value of the support of the hp pavilion zd7000 battery battery 100m ~ 1000mΩ. The company said the commentator, “because of the requirements of customers vary, therefore, according to the ESR value of different standards to prepare a variety of products, it is very difficult. And now may be in accordance with the requirements of customers for custom.” Electrostatic capacity as a result of the value of ESR values are slightly different, but in about 1μF.

TDK display for the size of 1.6mm × 0.8mm × 0.8mm of “1608″ type, and 2.0mm × 1.2mm × 0.85mm “2012″ ESR-control products. ESR value, type 1608 may be adjusted within the framework of  toshiba pa2487ur batterythe largest 1200mΩ, 2012 in the largest-500mΩ range of adjustment. The company has basically not prepared to standard products.

According to the Xinhua News Agency, Tokyo, October 20 (Reporter Qian Zheng) - Japan’s Matsushita Electric Industrial Co., Ltd. announced on the 20th, the company has developed a unit volume output in the past is the product of two direct methanol fuel cell for laptop computers, cell phones, etc. The use of portable devices. Pavilion XH216，Pavilion XH226，Pavilion XH260，Pavilion XH335，Pavilion XH35，Pavilion XH365，Pavilion XH395，Pavilion XH455，Pavilion XH485，Pavilion XH535，Pavilion XH545，Pavilion XH555，Pavilion XH575，Pavilion XH600，Pavilion XH635，Pavilion XH675，Pavilion XU155，

20, Matsushita said in its press releases, the company’s R & D to improve the fuel cell power generation, as well as some auxiliary power generation and electrical circuit components, re-design of the structure, so that the battery to reduce the size of the original 50. A new auxiliary electrical power circuit components and, when required amount of fuel can, the air supply to the power generation part of the increased power of the battery power

1, lithium-ion battery nominal voltage 3.7V (3.6V), charging cut-off voltage 4.2V (4.1V, the batteries under the brands have different designs). (Li-ion batteries is the norm: lithium ion secondary sony PCGA-BP2NY battery)

  2, to the requirements of lithium-ion rechargeable battery (GB/T18287 2000 norms): First of all, constant current charge, that is, a certain current, and battery charging voltage as the process of gradually increased, when the battery terminal voltage to reach 4.2V (4.1V), To charge for the current charging voltage, that is, a certain voltage, current batteries based on the degree of saturation, with the charging process to continue to gradually reduce, when reduced to 0.01C, that the termination charge. (C batteries based on current nominal capacity of a control method that, if the battery is a 1000mAh capacity, 1C charge current is 1000mA, attention mA is not mAh, 0.01C is 10mA.) Of course, that standard is 0.01 C5A, here I simplified.

  3, Why is that the charge for the end of the 0.01C: This is a national standard GB/T18287-2000 provided as well as the discussions. Previously it was generally for an end to 20mA, the Ministry of Posts and Telecommunications YD/T998-1999 industry standards provided for in the same way, that is, no matter how much dell U4873 battery  capacity, to stop all current 20mA. GB 0.01C provided help to more full charge, through the identification of a party manufacturers benefit. In addition, the national standard provides for the charging time is not more than 8 hours, that is, even if not yet reached 0.01C, 8 hours, and that the end of the charge. (No problem, the quality of the batteries should be 8 hours to reach 0.01C, the poor quality of the battery, wait and meaningless)

  4, what difference is the battery 4.1V or 4.2V: consumers do not have the distinction, depending on batteries manufacturer of the product specifications. Some brands of batteries are 4.1V and 4.2V common, such as A & TB (Toshiba), the domestic manufacturers is the basic 4.2V, but there are exceptions, such as Tianjin is the power of God 4.1V (but also by a 4.2V).

  5, the rechargeable batteries of 4.1V to 4.2V happen: will increase the capacity of the battery, with a good feeling, and standby time, but will reduce battery life. For example, the original 500, reduced to 300. By the same token, to the 4.2V batteries have been sufficient, it will lower its short-lived. Lithium-ion batteries is very delicate.

  6, since the battery inside a protective plate, we can rest assured that it had: No, because the board to protect the cut-off parameter is 4.35V (this is good, the bad to 4.4 to 4.5V), protection of the board is to meet in case If every time charge-off, the battery will decay quickly.

  7, much of the charge current is appropriate: In theory, the smaller of the more beneficial to the battery. But you can not order a dell G5266 battery  charge, such as 3 days now. GB provides low-rate charge is 0.2C (standard arbitration charge), but also to the top of the battery capacity of 1000mAh, for example, is 200mA, so we have this battery can be estimated more than 5 hours to full charge. (MAh = current capacity mA × time h)
  national technical supervision departments to identify capacity lithium-based high-rate charge of 1C to 0.2C low discharge rate, time to calculate the value of capacity, the number of Test 5, 1st capacity to reach the end of the trial. (5 is the chance that if the first pass a test on the back of the 4th does not) allow for testing before the first cycle in advance, in order to 1C is the current charge that 4.2V to cease, and not behind the constant pressure to 0.01 C process, but not 14 hours.

  8, lithium-ion batteries can withstand much of the charge current: factory tests can be very high, but the elevation ratio requirement for the country 1C, also above the cell, for example, more than 1 hour can be filled. Such a charge current, dell F5136 battery  can bear it? For the current lithium-ion batteries, is the only Xiaoyi Si. There are no national standards for the Chargers, enforced by the Ministry of Posts and Telecommunications is the industry standard YD/T998 1999 / 2, which provides for the current charger not to be more than 1C.

  9, and how life is provided for: to put it simply refers to the battery at 1C charge N after, 1C discharge, the capacity dropped to 70% at this time of the N is the life. Is not to say that 300 can also be used, the 301 can not be used. GB provides life shall be not less than 300. We usually do not detect the use of the conditions so harsh, life will be longer.

Yesterday, the news from Ningbo Inspection and Quarantine Bureau shows that in the future exports to Spain batteries, but also pay for the battery recycling.

September 26, 2008, Spain used battery recycling laws in force, the requirements of battery manufacturers and importers through the establishment of recycling, public finance to pay handling fees involved in the recycling of used 1×793 battery , and that departments concerned should adopt the most Advanced technology for recycling of used batteries for dealing with environmental protection.

The European Union on May 2 this year adopted a directive from the 2008 mandatory recycling of used batteries, the cost will be recovered to manufacturers of the burden. China’s dell battery production accounted for one-third of the world’s total output, and the Ningbo region to focus on the hundreds of battery manufacturers, the export volume of over 2,000,000,000, the European Union into the battery while the annual export volume accounting for three-cheng.
