摘　　要：从理论上对动力电池充放电效率的不同测试方法进行了分析,建立了电池充放电效率的测试模型,提出了直流脉冲法快速测试电池在不同放电率和放电深度下的充放电效率。同时采用不同的测试方法测试了不同动力电池的充放电效率,分析了不同放电率和不同放电深度对电池效率的影响。直流脉冲法和其它测试方法相比,测试结果基本相同,但这种测试方法可以缩短测试的时间。The different test methods of traction battery efficiency were analyzed theoretically and the efficiency test models were setup. A test method called DC pulse was brought up to test the charging and discharging efficiency under different depth of discharge and different discharge rates. Different battery efficiency including Pb-lead and NiMH were determined by different methods and the effects of different depth of discharge and different charging and discharging rates was analyzed. DC pulse test results are similar to other methods test results but with shorter test time.
