The invention provides a battery heating method and device, a battery management system, a battery system and a vehicle, and relates to the technical field of batteries. And under the condition that the heating judgment parameter meets a preset warm air heat energy heating condition, heat energy of a warm air system of the vehicle is used for heating a battery of the vehicle. The battery of the vehicle is heated by introducing the heat energy in the warm air system of the vehicle, and an additional heat source does not need to be introduced in the battery heating process, so that the energy consumption of the whole vehicle is reduced.

    本申请提供一种电池加热方法、装置、电池管理系统、电池系统及车辆,涉及电池技术领域,方法包括:获取车辆的加热判决参数;在所述加热判决参数满足预设的暖风热能加热条件的情况下,使用所述车辆的暖风系统的热能对所述车辆的电池进行加热。本申请引入了车辆的暖风系统内的热能对车辆的电池进行加热,可以在对电池加热的过程中无需引入额外的热源,从而降低了车辆的整车能耗。
