A method and a device for controlling battery heating is disclosed. The method comprises: 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 include at least one of the following: (a) an absorbed energy Q of the battery reaching a predetermined energy QSET; (b) a time period Ti during which a discharging current I of the battery maintains constant (c) the discharging current I starting to decrease when a predetermined time period TSET is reached; and (d) a heating time period T reaching a predetermined maximum heating time period Tmax. The method and the device consider multiple conditions, for example, temperature, discharging current, battery State-of-Charge, heating time, etc. to determine when to stop battery heating, which may further enhance the operating efficiency and lifespan of the battery.
