摘要
电驱动系统是混合动力汽车的动力源。对串联式混合动力电动汽车的电驱动系统进行了结构分析和部件设计,在分析其工作模式的基础上,确定了峰值电源最大荷电状态的控制策略,基于Matlab软件对该电驱动系统建立了仿真模型。仿真试验分析表明,该控制策略将循环通过电动机和峰值电源的部分发动机能量最小化,从而减少发动机能量传递的损耗。建立的模型是合理有效的,为混合动力汽车整车的动力性、经济性等提供了仿真平台。
In this paper, the electric driving system for hybrid electric vehicle was designed. Based on the fundamental working modes of the hybrid electric vehicle, a maximum state of charge control strategy was adopted to control the engine and the battery , which keeps the battery SOC in a reasonable range. Corresponding models of components are built to realize the cleetric driving system. Simulation analysis method was used to investigate the working conditions of this system. The simulation results showed that the target gained by the control strategy can balance the power output demand and make up the battery energy shortage.
