目的:对混联式混合动力汽车的功率分配和运行性能进行分析和研究。方法:在混合动力汽车功率分配策略下,基于AMESim软件建立混联式混合动力汽车仿真模型,再与IFP Exhaust排放库进行联合仿真,分析发动机、电动机和发电机的功率变化下发动机和电池的运行性能,在NEDC工况下,探究电池容量和电机启动功率对混合动力汽车经济性和排放性的影响。结果:平均电池容量每增加1 Ah,平均油耗降低0.28%;平均电机功率每增加1 kW,平均油耗降低0.61%。结论:电池容量越高经济性和排放性越好,电动机启动功率越大经济性越好。

Objective: To analyze and study the power distribution and operation performance of hybrid electric vehicle.Methods: Based on the power distribution strategy of hybrid electric vehicle, the simulation model of hybrid hybrid electric vehicle was established based on AMESim, and then co-simulation was conducted with IFP Exhaust emission library to analyze the operating performance of engine and battery under the power changes of engine, motor and generator. Under the NEDC working condition, the influence of battery capacity and motor starting power on economy and emission of hybrid electric vehicle was investigated. Results: When the average battery capacity increased by 1 Ah, the average fuel consumption decreased by 0.28%. When the average motor power increases by 1 kW, the average fuel consumption decreases by 0.61%. Conclusion: The higher the battery capacity, the better the economy and emission, and the higher the motor starting power, the better the economy.
