Abstract
The battery pack of LiFePO4 and MH-Ni were selected as the concrete study subject. This paper pointed out a kind of method to test the energy efficiency of the battery, the constant current and pulse of charge and discharge energy efficiency were analyzed. The results of analysis show the energy efficiency of battery pack is in connection with SOC and current., and the energy efficiency of LiFePO4 is higher than MH-Ni, which provide technical support for improving power characteristic of EV and HEV.
