摘　　要：在设计2015年赛季电动赛车时,为使赛车的布置更为紧凑,在保证电池容量的情况下,采用高放电倍率的锂电池,缩小了电池组体积,采用了动力电池后置在座椅背部的方案。同时,为避免因采用高放电倍率单体、动力电池紧凑化设计而造成动力电池散热不良的情况发生,利用整车运动仿真模型计算出不同时段的动力电池热生成率,在此基础上对其热特性及温度场分布进行了研究分析,并根据仿真结果设计了电池箱的强制风冷散热结构,再次进行仿真验证。最终仿真结果表明,在比上赛季电动赛车动力电池减重20kg的情况下,增设了散热结构的动力电池新结构在整个行驶过程中能保持良好的工作状态,本研究为今后FSE赛车电池组设计提供了一定的理论依据。A set of high rate discharge lithium battery was allocated at the back of cockpit in the 2015 FSEC race car design so that the battery pack occupied less space and the interior arrangement could be more compact.Furthermore,the heat generating rate of power battery was calculated according to the vehicle dynamic simulation model,and its heat feature and temperature distribution were analyzed in order to avoid poor battery cooling due to high rate discharging and compact design.A new forced air-cooling structure was designed according to the simulation result,and it was also testified by program simulation.The final simulation result demonstrates that,the new structure of power battery which contains an added cooling device can work well when the battery system is 20 kg lighter than that of the old project.The research of this paper provides references for the battery design of FSE race cars.
