Beschreibung
Zusammenfassung:	A battery self-heating device and a vehicle. The device comprises a battery self-heating circuit and a controller. The battery self-heating circuit comprises a first battery pack, a second battery pack, a bridge arm, and a winding corresponding to the bridge arm. A negative electrode of the first battery pack is connected to a positive electrode of the second battery pack, and the negative electrode of the first battery pack and the positive electrode of the second battery pack are connected to an output end of the winding. An input end of the winding is connected to a midpoint of the bridge arm. A positive electrode of the first battery pack is connected to a first bus end of the bridge arm. A negative electrode of the second battery pack is connected to a second bus end of the bridge arm. The controller is configured to adjust the duty ratio of the bridge arm according to a target duty ratio range. Dispositif de chauffage automatique de batterie et véhicule. Le dispositif comprend un circuit de chauffage au
