The embodiment of the invention provides an electric vehicle battery heat preservation control method, device and system and an electric vehicle, and relates to the technical field of electric vehicles. The electric vehicle battery heat preservation control method comprises the steps that first heat preservation duration set by a user is obtained through a multimedia vehicle machine, and charging heat preservation duration is updated to be the first heat preservation duration; whether the battery heat preservation action is allowed to be executed or not is judged by combining the whole vehicle state of the electric vehicle; when the battery heat preservation action is allowed to be executed, the battery heat preservation action is executed according to the charging heat preservation duration. According to the embodiment of the invention, battery heat preservation control can be carried out according to different travel requirements of users, and the technical effect that the battery performance of the electric automobile is still kept in a good state when the users use the automobile is ensured.

    本发明实施例提供一种电动汽车电池保温控制方法、装置、系统及电动汽车,涉及电动汽车技术领域。所述电动汽车电池保温控制方法包括:通过多媒体车机获取用户设置的第一保温时长,将充电保温时长更新为所述第一保温时长;结合电动汽车的整车状态,判断是否允许执行电池保温动作;当允许执行电池保温动作时,根据所述充电保温时长执行电池保温动作。本发明实施例能够实现适应用户的不同出行需求进行电池保温控制,保证用户用车时电动汽车的电池性能仍维持在良好状态的技术效果。
