摘　　要：为了更好地模拟动力电池的动态特性,开发相应的控制策略,建立了适用于电动汽车的动力电池仿真平台,并且分别建立了动力电池剩余电量模型、最大充放电功率模型和电池热模型.基于电动汽车的不同工况进行了动力电池系统的仿真.结果表明,所建立的动力蓄电池模型能够很好地模拟电动汽车运行过程中蓄电池组的动态行为,为动力蓄电池管理系统软、硬件的开发和电动汽车整车控制策略的开发提供了良好的平台.Battery is the key component of electric vehicles. In order to simulate the dynamic behavior of the battery and develop the corresponding control strategy, a simulation system for battery was developed. The battery state of charge model, maximal charge and discharge power model and thermal model were also presented. The battery simulation was done based on the different drive cycles. The simulation results show that the battery models could simulate the dynamic behavior of the battery. The simulation system provides a good platform for the development of battery management system and vehicle control strategy.
