The disclosure provides a method (100A) of controlling a position of a motor rotor for power battery during pulse heating. It enables the position of the motor rotor to converge within an allowable position range of pulse heating as a goal orientation, and performs a PI control. If the PI control fails, a security mechanism will be activated. Finally, there are two states, one is that the position of the motor rotor converges within the allowable position range of the pulse heating, and the other is that the pulse heating function is exited and a fault is reported. In this way, a frequent start and stop of pulse heating may be prevented from affecting a duration life of the motor and the power battery, which ensures a safety of a vehicle.
