【摘要】 动力蓄电池是混合动力车辆(HEV)的功率补充系统,在整车控制策略过程中需要了解电池的峰值输出功率。选择了多段脉冲放电和恒功率放电的电池功率测试方法,比较了研究HEV小轿车用镍氢动力电池的10s峰值输出功率。结果表明:通过采用多段脉冲放电的测试方法,并采用指数函数进行预估,得出的电池峰值输出功率与通过恒功率放电方法得出的结果比较一致。更多还原

【Abstract】 Power battery as the power supply system of HEV, the peak power of the battery should be known in order to control the HEV.The methods of multi-pulse discharge and constant-power discharge were selected to study the peak output power of rectangular Ni-MH battery at 10 s for HEV.The results show that the peak output power calculated by exponential function using multi-pulse discharge is consistent with the one obtained from constant-power discharge.更多还原
