In view of the problem of short driving range of pure electric vehicles, the structural analysis and key parameters matching for a range-extended electric vehicle developed are conducted. Based on AVL-Cruise / Simulink co-simulation platform with an on-off power management strategy adopted, a simulation verification is conducted on the powertrain designed. The results demonstrate that the powertrain designed and parameters matching are relatively rational, so the highly efficient operation of range extender can be achieved with the driving range of e-lectric vehicle effectively extended.%针对电动汽车续驶里程短的问题,为开发的增程式电动汽车动力系统进行了结构分析和主要参数匹配.基于AVL-Cruise/Simulink联合仿真平台,采用定点能量管理策略,对设计的动力系统进行了仿真验证.结果表明,整车动力系统的设计和参数匹配比较合理,能实现增程器的高效工作和有效延长电动汽车的续驶里程.
