    Abstract: The present invention discloses a method and a device for controlling battery heating. The method may comprise the following steps of: starting battery heating when conditions for starting battery heating are met; and stopping battery heating when conditions for stopping battery heating are met. The conditions for stopping battery heating may be at least one of the following: (a) an absorbed energy of the battery reaching a predetermined energy; (b) a period of time during which a discharging current of the battery maintains constant reaching a predetermined period of time; (c) the discharging current starting to decrease; or a heating time reaching a maximum heating time. The method and the device according to the present invention consider a plurality of conditions including temperature, discharging current, battery SOC and heating time etc. to determine battery heating, which may meet requirements of the practical applicabilities and may not damage the battery with enhanced battery lifespan.
