A vehicle starting method, a power supply, and a vehicle are provided. The method includes: obtaining a voltage of a first battery of the vehicle by an external power supply; and when the voltage of the first battery is lower than a first voltage threshold, controlling a second battery of the external power supply to supply power to the vehicle, to start the vehicle. In this way, whether the first battery has an insufficient voltage may be determined by obtaining the voltage of the first battery of the vehicle, and after it is determined that the first battery has the insufficient voltage, electrical energy for starting the vehicle is provided by the second battery of the external power supply, to start the vehicle. In embodiments of this application, the vehicle starting method and the external power supply can provide low voltage electrical energy for starting the vehicle when a vehicle-mounted low voltage storage battery of a battery electric vehicle or a hybrid electric vehicle is an insufficient voltage state.
