A new judgment standard for discharging ending status of lead-acid battery

The battery pack was an important part of EV. How to extend the using life of the battery were the problems that should be solved in the development of the EV and HEV. First the battery pack should be prevented from over discharge, the judgment of the discharging ending status of the battery should be timely and accurate. It pointed out the defects of general judgment standards for discharging ending status of lead acid battery for electric vehicles and then advances a new method for judging the discharging ending status of the battery the voltage capacity slope method.
