The embodiments of the present application provide a control method of a power battery heating system, and a power battery heating system. The control method includes: sending a first heating signal to a switch module, where the first heating signal is configured to control all upper bridge arms of a first bridge arm group and all lower bridge arms of a second bridge arm group to be turned on, and control all lower bridge arms of the first bridge arm group and all upper bridge arms of the second bridge arm group to be turned off, so as to form a first loop; and sending a second heating signal to the switch module, where the second heating signal is configured to control all the lower bridge arms of the first bridge arm group and all the upper bridge arms of the second bridge arm group to be turned on, and control all the upper bridge arms of the first bridge arm group and all the lower bridge arms of the second bridge arm group to be turned off, so as to form a second loop The first loop and the second loop are configured to generate heat by a current in the power battery to heat the power battery, and both a spatial phase difference between a three first windings and a spatial phase difference between a three second windings are 120°.
