摘　　要：选取合适的动力电池模型用于混合动力汽车控制策略设计和性能仿真。比较分析了基于等效电路的电压-内阻模型和PNGV动态模型,提出了基于测试数据的特性场模型。以功率型N iMH动力电池组为例,进行了模型参数的辨识。仿真结果与实验结果对比表明:特性场模型和PNGV动态模型具有相近的精度,但PNGV动态模型的精度与模型参数的辨识结果密切相关,电压-内阻模型简单适用于稳态仿真。To obtain suitable models of power battery pack for control strategy design and performance simulation of hybrid electric vehicle, the open circuit voltage model and the PNGV dynamic model based on equivalent circuits of the power battery are introduced and compared. A characteristic field model based on experiment data is built. For a NiMH Power battery pack, parameters of the three models are obtained. Comparisons between the simulation and the experiment show that the characteristic field model and the PNGV dynamic model are more accurate. But the accuracy of the PNGV model depends on the model parameters. And the open circuit voltage model is simple and only suitable for the steady simulation.
