摘要
针对低温环境下用户抱怨纯电动汽车实际续航里程缩减严重的问题,开展了纯电动汽车用户行驶习惯特征的大数据分析,得出了用户单程行驶里程和单程行驶时间的主要行驶习惯特征参数。并提出了一种基于纯电动汽车用户行驶习惯特征的分模式电池加热控制策略,确定了分模式电池加热控制策略参数,为后续进一步研究纯电动汽车电池热管理控制策略仿真分析和整车试验验证提供基础。
This paper has carried out the research on the driving characteristics about pure electric vehicle users in order to alleviate the actual endurance mileage reduction problem in a cold environment.The results showed the main driving characteristics including the one-way driving mileage and the one-way driving time.And this paper proposed the different modes battery heating control strategy based on the driving characteristics of pure electric vehicle users,and optimized the parameters of the control strategy as well,which provided reference for the sequential studies including the simulation analysis of battery thermal control strategy and the test validation of pure electric vehicle.
