摘要

For consideration of the coupling influences on Peukert model of high power Ni-MH 80Ah battery from current (26.7~160A)and temperature (-20~50 ℃),applicability of Peukert model was analyzed.Research showed that Peukert model was applicable to the high power Ni-MH battery at 20~40 ℃,and its coefficient was 1.0681,which demonstrated the excellent per-formance of high-rate discharge,the current range applied to Peukert became narrower at-20 ℃and 50 ℃,and Peukert coefficient had a strong correlation with temperature.%以高功率型80Ah 氢镍动力电池为研究对象，在电流（26．7～160 A）和温度（-20～50℃）范围内，对其 Peukert 模型温度效应进行了分析。研究表明：在20～40℃的温度范围内，Peukert 模型是可以应用于高功率型氢镍电池，且模型参数为1．0681，表征了该型氢镍动力电池良好的倍率放电特性；高温和低温都会导致 Peukert 模型的应用电流范围变窄；Peukert 模型参数与温度具有强相关性。
