The invention discloses a parameter matching method for a composite power supply system of an electric vehicle. In parameter matching of a hybrid power supply system of the electric vehicle, a multi-objective optimization model taking endurance mileage and total mass of a super capacitor and a storage battery of the electric vehicle as objective functions and taking capacities of a power battery monomer and a super capacitor monomer as optimization variables is established, and a weighting coefficient method is used for solution. Through the method, the power system parameters meeting the performance indexes can be calculated and optimized, so that the total mass of the hybrid power system is reduced, and the driving range of the electric vehicle is increased.
本发明公开了一种电动汽车复合电源系统参数匹配方法,本发明在电动汽车的复合电源系统参数匹配中,建立了电动汽车的续航里程及超级电容、蓄电池总质量为目标函数,以动力电池单体和超级电容器单体的容量为优化变量的多目标优化模型,并利用加权系数法进行求解。通过以上方法可以计算优化出满足性能指标的动力系统参数,从而减少复合电源系统总质量,增加电动汽车续驶里程。
