Zusammenfassung:	The embodiment of the invention relates to the field of vehicle control, in particular to a vehicle battery control method and device. After the power battery is subjected to high voltage, if it is determined that the vehicle is in a high-voltage standing state according to the vehicle speed information and gear information of the vehicle and the current value of the power battery, whether the power battery is in a to-be-closed state or not is determined according to the battery temperature and the battery voltage of the power battery, and if the power battery is in the to-be-closed state and the duration time exceeds a first threshold value, the power battery is turned off. If yes, a power battery closing request is sent to a vehicle control unit VCU, so that the VCU sends a power battery closing instruction and closes the power battery according to the power battery closing instruction. In the embodiment of the invention, when the vehicle is in the high-voltage standing state, if the power battery is determ
