摘    要:对于新能源汽车而言,动力电池的峰值功率对其电池管理系统控制系统的设计及动力匹配的优化有重要的意义。提出一种峰值功率估计的测试方法,即对电池进行恒功率充放电,用该测试方法对常温下电动汽车用铅酸电池不同SOC点的峰值功率进行测试。结果表明,通过对电池进行恒压充放电所得到的峰值功率的预估值与测试结果相同,通过这一方法可以很方便地对持续时间不同的电池的峰值功率进行测试。

关 键 词:电动汽车  动力电池  峰值功率  恒压充放电

Abstract:For the electric vehicle,the peak power of the power battery is important for the design of the control system of the battery management system and the optimization of the power matching.A peak power estimation test method was presented,namely the constant power charging and discharging of the battery.Through the test method,the peak power of lead-acid battery with different SOC was tested.The results show that the predicted peak power is the same with the tested values.So,this method can easily test the peak power with different duration.
Keywords:electric vehicle  power battery  peak power  constant-voltage charging and discharging
