摘　　要：为了改善蓄电池作为单一能源的电动汽车很难满足瞬时大电流充放电的问题,在纯电动汽车中加入超级电容和双向DC/DC变换器构成电动汽车复合储能系统,通过对复合储能系统工作模式进行分析,建立了复合储能系统能量管理策略.利用CRUISE软件对基于复合储能系统的电动汽车进行建模,建立中国城市道路典型循环工况,在中国城市道路典型循环工况下对整车进行仿真,仿真结果表明电动汽车复合储能系统中,超级电容能瞬时大电流充放电,且可以保持蓄电池小电流平稳输出,从而减小了对蓄电池的损害,延长蓄电池的使用寿命.In order to improve the issue that it is hard to meet transient large current charging and discharging of vehicle with only battery, which leads to short driving range, a super capacitor and bidirectional DC/DC converter were added to pure electric vehicles constituting the electric vehicles compound energy storage system. The management strategy was established through analyzing compound energy system operating mode. With the help of soft- ware CRUISE, the electric vehicle of compound energy storage was modeled, and then we established Chinese ur- ban road driving cycle conditions, and the vehicle was simulated under the driving cycle conditions. The simulation results show that in the compound energy electric vehicle, super capacitor can charge and discharge in large current instantaneously, and the battery can be kept stable output with small current , thereby reducing damage to battery and increasing its service life.
