电动汽车用磷酸铁锂电池充放电特性实验研究
Experimental study on charging and discharging properties of LiFePO4 batteries for electric vehicles
摘要
Abstract
The electric vehicle has various driving conditions,so the battery charging and discharging performance greatly changes with the driving status.In order to improve the efficiency of the battery,it is necessary to learn the battery efficiency under different conditions.A series of charge and discharge experiments were done with 38.4 V/40 Ah LiFePO4 batteries by using ARBIN power battery test system.And the charge and discharge efficiency properties were analyzed with various currents and SOC.The theoretic model and fitting model for the battery efficiency were conducted based on the test results,and the fitting model was verified with new test data.The built battery efficiency fitting model can be used to optimize the electric vehicle performance on various driving conditions.关键词
