摘要
以某款增程型电动轿车为研究对象,在整车性能指标和系统结构确定的基础上,从电驱动系统、电储能系统、增程器及控制模式等方面出发,对整车动力系统进行了参数匹配分析及相关试验研究。同时通过Matlab/Simulink和Advisor联合仿真,在NEDC循环工况下对E-REV动力性进行了仿真分析。仿真及试验结果表明:发动机转速在2800r/min时可保证发电功率为6kW,电池SOC变化曲线符合电量耗尽模式控制策略,驱动电机输出转矩满足E-REV行驶动力性要求,所确定的动力系统方案满足整车基本性能要求。
Taking an extended-range electric car as example, based on the definite vehicle performance and system architecture, the parameter matching analysis and related experimental study of powertrain including electric drive system, energy storage system, extended-range equipment and control modes so on were carried out. Through the co-simulation of Matlab/Simulink and Advisor, the drivability of E-REV was simulated in the NEDC driving cycle. The simulation and test results show that the generated power is ensured 6 kW, when the engine speed is 2 800 r/min. The SOC curve of battery abides by the control strategy of charge depleting mode, and the torque output of motor meets the driving performance of E-REV. The definite scheme of powertrain can meet the primary performance requirements of E-REV.
