Design and Development for Auto Selected System Based on Battery Synthetical Features

Lithium battery group is widely used.The features of Lithium battery group based on each battery.It is difficult for the same features of every battery in production,so batteries should be selected to divide into groups according to their features.At present,manufacturers of Lithium battery adopt manual select method.The efficiency is very low and the quality of divided battery group is not good.A method of auto selected and divided battery group is proposed.The method based on battery synthetical features,such as charge curve,discharge curve,inter-resistance,capacity,self-discharge and so on.This method may improve efficiency of selected battery and quality of divided battery group.
