摘　　要：针对目前纯电动汽车电池寿命衰减快导致其使用成本高的问题,分析目前常规纯电动汽车动力系统参数匹配的方法和不足,以及电池循环寿命的影响因素,在此基础上,提出基于电池循环寿命的纯电动汽车动力系统参数匹配方法,该方法在保证纯电动汽车动力性和经济性的基础上,以动力电池容量衰减率最低为目标对纯电动汽车动力参数进行匹配。以某款纯电动汽车为研究对象,运用ADVISOR仿真软件,结合电池寿命理论模型,建立纯电动汽车整车仿真模型,运用所提出的方法确定该车的动力系统参数。研究结果表明,运用基于电池循环寿命的纯电动汽车动力系统参数匹配方法所设计的纯电动汽车动力系统,在一个NEDC循环工况下动力电池容量衰减率降低了2.41%,从而降低了电动汽车使用成本。Aiming at the problem that the battery life of the pure electric vehicle is low which leads to high cost,the method and the shortcomings of the parameters of conventional pure electric vehicle power system and the influence factors of the battery cycle life are analyzed.On this basis,a method of pure electric vehicle power system parameters design based on the cycle life of power battery has been proposed.Ensuring the power and economy of pure electric vehicle,the method can match the dynamic parameters of pure electric vehicle with the lowest decay rate of power battery capacity.Taking the pure electric vehicle as the research object,using the ADVISOR simulation software and the battery life theory model,the pure electric vehicle simulation model is established,and the dynamic system parameters are determined.The results show that the power battery capacity of the pure electric vehicle based on the above method is reduced by 2.41% under a NEDC cycle condition,which could reduce the cost of electric vehicles.
