摘要:
为了给电动汽车驱动系统的参数匹配和电机控制器的技术改进提供理论依据,通过分析动力电池组直接供电的电机驱动系统特性,研究其对电动汽车整车性能的影响。依据动力电池的简化等效模型,从负载角度分析讨论了电池的放电特性;并以由奥拓车改装成的纯电动汽车运行工况为例,研究得到48 V电池组放电特性的仿真与实测结果。结合异步电机机械特性和驱动系统特性实例分析,深入讨论了电池组直接供电的驱动系统对整车性能的影响。研究结果表明,由于电动汽车运行工况复杂多变,电池组直接供电存在控制器电压波动频繁、系统大功率需求时电压跌落与供电能力不足等问题,致使电机驱动系统的最大转矩输出与效率的恶化,以及整车最高车速、爬坡及加速能力的降低。
