Abstract: A method for controlling heating of a battery pack is provided, in which, the method includes: acquiring a temperature of the battery pack; and controlling a motor controller to output a current to a motor, if the temperature of the battery pack is lower than a preset temperature threshold, so as to generate a magnetic field in the motor having a magnetic pole direction consistent with or opposite to a magnetic pole direction of a motor rotor and to enable the motor to maintain a stationary state.
