The present application provide a control method of a power battery heating system. The method includes: controlling 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 controlling 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; controlling 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 controlling 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 method is used to heat the power battery.
