Abstract: Embodiments of the present disclosure provide a battery heating system, a battery assembly and an electric vehicle. The battery heating system includes: a battery group having a positive pole and a negative pole; a switch having a first end connected with the positive pole; a large-current discharge module, and a controller connected to the switch and configured to control the switch according to a temperature of the battery group. A first end of the large-current discharge module is connected to a second end of the switch, and a second end of the large-current discharge module is connected to the negative pole. When the switch is turned on, the battery group discharges via the large-current discharge module and the battery group is heated due to an internal resistance thereof.

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.
