增程式电动汽车又称里程延长式电动汽车,作为纯电动汽车的平稳过渡车型,以其效率高,电池容量小,不会因缺电抛锚等优点受到了广泛的关注。该文针对燃油增程式电动汽车的动力部件选型、动力系统配置、系统协调控制与效率优化等关键技术问题进行了分析研究。对比分析国内外相关技术方案的同时,结合自主研发的一款增程式电动汽车进行了动力系统关键技术的探讨。最后,展望了增程式电动汽车的技术发展,提出了几个值得关注的相关重要研究课题与研究方向。
The extended range electric vehicle (EREV or REEV), as a transition vehicle type from custom engine vehicle to the electric vehicle, has become a hot point of the global automobile industry research and development because it’s no drop anchor for power shortage, high efficiency and low battery capacity required. In this paper, power component selection, power configuration, efficiency optimization and coordination control of EREV are analyzed. Combined with the independent developed EREV, the specific research of the key technologies is presented. In addition, we point out the notable related important research subjects and directions in this paper.
