The invention relates to a battery heating method and device, a vehicle and a medium, and relates to the technical field of battery heating, and the method comprises the steps that in response to a heating request, batteries of a plurality of electric vehicles are divided into a first battery pack and a second battery pack, the heating request is used for requesting to heat the batteries of the plurality of electric vehicles, and the first battery pack and the second battery pack are connected; the plurality of batteries are connected with the bidirectional converter; the bidirectional converter controls the first battery pack and the second battery pack to mutually discharge back and forth so as to heat the plurality of batteries. The batteries of the plurality of electric vehicles store more electric energy, and the plurality of batteries participate in self-heating, so that the current in the self-heating process is larger, more heat is generated, and the self-heating effect of the batteries is improved.

    本公开涉及一种电池加热方法、装置、车辆及介质,涉及电池加热技术领域,所述方法包括:响应于加热请求,将多个电动汽车的电池划分为第一电池组和第二电池组,加热请求用于请求对多个电动汽车各自的电池进行加热,多个电池与双向变换器连接;通过双向变换器控制第一电池组和第二电池组来回相互放电,以实现对多个电池进行加热。多个电动汽车的电池存储的电能较多,多个电池参与自加热,使得自加热过程中的电流较大,产生的热量较多,提升了电池自加热效果。
