A vehicle battery thermal management system includes a heat conducting element connected to a vehicle air conditioning system and a self-heating circuit connected to a vehicle power battery. The heat conducting element, a compressor of the vehicle air conditioning system, and an outdoor condenser of the vehicle air conditioning system form a battery refrigeration loop, and the battery refrigeration loop absorbs heat from the vehicle power battery through a refrigerant in the heat conducting element to cool down the vehicle power battery. The self-heating circuit and the vehicle power battery form a battery self-heating loop, and the self-heating circuit is configured to control the vehicle power battery to perform high-frequency alternating charging and discharging for self-heating in the battery self-heating loop.
