基于Advisor的纯电动汽车整车性能参数化分析

Parametric Performance Analysis on Electric Vehicle Based on Advisor

提高纯电动汽车整车动力性能和续驶里程,电池和电机的选用非常关键。文章介绍了纯电动汽车结构;对比分析了在纯电动汽车上常用的电机和电池类型及性能参数;在Advisor软件中分别针对电机和电池的参数对续驶里程和动力性的影响进行仿真,得出了其对整车性能的影响;进一步推导出了电池电量与续驶里程的函数关系,为实际应用中选用电池类型,核算电量成本等提供了经验公式。

Choosing battery and motor play an important role in enhancing power performance and cruising range of the pure electric vehicle （EV）. The paper introduces the structure of EV and analyzes the types and peri＇ormance parameters of motor and batte,7 on EV. In the software of Advison based on the influence exerted by the parameters of motor and battery, the paper conducts simulation of cruising range and power performanance and thus that influence on the whole vehicle is obtained. Further, the functional relationship between the state of charge of battery and cruising range is deduced and the empirical formula for choosing battery and accounting the cost of the state of charge in daily life are provided.
