Abstract:
A vehicle starting method, a power supply and a vehicle (10), the method comprising: an external power supply (20) acquiring the voltage of a first battery (110) of a vehicle (10); and when the voltage of the first battery (110) is lower than a first voltage threshold, controlling a second battery (220) of the external power supply (20) to supply power to the vehicle (10), so that the vehicle (10) is started up. Therefore, it is possible to determine whether the first battery (110) lacks power by acquiring the voltage of the first battery (110) of the vehicle (10), and after it is determined that the first battery (110) lacks power, the second battery (220) of the external power supply (20) provides electrical energy that is required for starting up the vehicle (10), so as to start up the vehicle (10).
