A vehicle battery thermal management system, a vehicle thermal management system, and an electric vehicle are disclosed. The vehicle battery thermal management system includes: a heat conducting element (2) connected to a vehicle air conditioning system (1) and a self heating circuit (4) connected to a vehicle power battery (3). The heat conducting element (2), a compressor (101), and an outdoor condenser (102) constitute a battery refrigeration loop, and the battery refrigeration loop absorbs heat from the power battery (3) through a refrigerant in the heat conducting element (2) to cool down the power battery (3). The self heating circuit (4) and the power battery (3) constitute a battery self heating loop, and the power battery (3) implements high-frequency alternating charging and discharging for self heating through the self heating circuit (4) in the battery self heating loop.
