Current power lithium battery power supply system development The main question is: power battery into a group of security and life after the significant decline, and even frequent battery fire, explosions and other serious accidents. Laptop Battery The main reason contributing to this problem is the power lithium battery group technology, group study of applied technology and equipment, lagging; to achieve power lithium battery system integration, to provide users with power lithium battery system integration technology and products to solve the current problem and promote the development of lithium battery power important subject.At present, the single power lithium battery has been basically have the popularization and application of conditions, but the existing group technology, group applied technology and equipment levels are not yet ripe. In other words, single power lithium battery basically solved the safety and life issues, and proactol promote the development of lithium battery power, the key is the battery technology, group technology and BMS. Toshiba A70 battery PA3062U-1BAT batteryDetermine the quality of single cells into a group of post-power battery quality. In the power battery applications, the single cell performance consistency is especially important, given the present level of single cell manufacturing process control, through the battery produced in accordance with its actual performance to filter, group, assembly is a realistic way. At present, the application of industrial production screening, grouping method is based on the battery post into a few static parameters, with the battery group, with set of parameters that control standard determines the distribution group completed the battery when the battery status of each single line sex. In the battery pack in use, the battery group differences in each single state of the battery will gradually appearing.
