The invention relates to a thermal management control method and system for an intelligent battery of an electric vehicle. The method comprises the following steps: acquiring the vehicle geographic latitude, the local environment temperature, the vehicle battery temperature and the battery charge state of the vehicle; according to the geographic latitude of the vehicle, judging whether the vehicle is north or south; judging whether the battery thermal management mode enters a cooling mode or a heating mode according to the vehicle battery temperature; and based on the position of the automobile and the battery thermal management mode, according to the local environment temperature, the battery charge state, the preset cooling mode threshold mapping table or the preset heating mode threshold mapping table, different battery thermal management cooling strategies or different battery thermal management heating strategies are correspondingly executed. Therefore, cooling or heating strategies in different modes can be intelligently matched according to the geographic position of the vehicle, the local environment temperature, the vehicle battery temperature and the battery charge state, the driving experience is improved, the vehicle energy consumption is optimized, and the service life of the battery is prolonged.

    本发明涉及一种电动汽车智能电池热管理控制方法及系统。该方法包括如下步骤:获取汽车的车辆地理纬度、当地环境温度、车辆电池温度、电池荷电状态;根据车辆地理纬度,判断汽车所在位置为北方或者南方;根据车辆电池温度,判断电池热管理模式进入冷却模式或者加热模式;基于汽车所在位置及电池热管理模式,且根据当地环境温度及电池荷电状态,预设冷却模式阈值映射表或预设加热模式阈值映射表,分别对应执行不同电池热管理冷却策略或不同电池热管理加热策略。因此能根据车辆所在地理位置、当地环境温度、车辆电池温度、电池荷电状态,智能匹配不同模式下的冷却或加热策略,提升了驾驶体验、优化了车辆能耗、并且延长了电池的使用寿命。
