摘 要: 在多能源电动汽车的模型基础上,针对能量管理系统(EMS)该文提出了一种功率比较控制策略。EMS的功率比较控制策略是通过比较实际所需功率和能量存储元件的最大提供和吸收功率来达到分配功率的目的。同时提出了最大提供功率和吸收功率的确定方法。仿真结果表明:功率比较控制策略比简单查表控制策略在续驶里程、燃料经济性和效率等方面均有所改善。 In this paper we propose a power comparison control strategy for energy management system based on a model of energy hybridization EV. Power comparison control strategy of EMS is performed through comparison between the actual required power and the maximum supplying and absorbing power of energy storage components in order to distribute the power. Meantime determination methods of maximum supplying and absorbing power of energy storage components are described. Simulation result shows that the driving range,the fuel economy and efficiency of power comparison control strategy have rapidly improvee compared with the simple table look-up control strategy.
