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.

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.

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.

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
