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. The control method is able to acquire the temperature of the battery pack, and to control the motor controller to output a current to the motor when the temperature of the battery pack is lower than the preset temperature threshold, so as to generate the magnetic field in the motor having the magnetic pole direction consistent with or opposite to the magnetic pole direction of the motor rotor and to enable the motor to maintain the stationary state. In this way, it is realized that when the vehicle is in the stationary sate, by controlling the battery pack to actively discharge power to generate heat, the working temperature of the battery pack is improved, thereby tackling the problem of poor working status and low discharge efficiency in the prior technology caused by the low working temperature of the battery pack. Furthermore, the control method of the present disclosure does not require other electrical components, which greatly saves costs.
