温度对磷酸铁锂动力锂离子电池性能的影响

摘要

在不同温度下对32131-8Ah圆柱锂离子电池进行电学性能测试，考察了温度对锂离子电池放电性能的影响。结果表明：温度对锂离子电池的充放电倍率、放电功率、电阻及不同荷电状态（SoC）下的放电能力都有较大的影响，其中在常温下基本都能达到最优结果，温度上升或者下降都会对电池造成不同程度的负面影响。%In this paper,the electrical performance of Li-ion battery of IFR 32131-8Ah is measured and analyzed at different temperatures.This test investigates the effect of temperature on the dis-charge performance of Li-ion battery.The results show that the temperature has a great influence on the charge and discharge power,resistance,and the discharge capacity under different SoC. Furthermore,the optimal results could always be gotten at the room temperature.Temperature rising or falling always cause different degrees of negative effects on battery cells.
