The invention discloses a heating control system of a power battery and an automobile. The heating control system comprises a first bridge arm converter, a second bridge arm converter and a vehicle-mounted controller, the first bridge arm converter is connected with the power battery and a winding of the first motor; the second bridge arm converter is connected with the power battery and the winding of the second motor; the winding of the first motor and the winding of the second motor are connected through a current transmission line. And the vehicle-mounted controller is connected with the first bridge arm converter and the second bridge arm converter and is used for controlling the first bridge arm converter and the second bridge arm converter to work, so that the power battery charges or discharges the winding of the first motor and/or the winding of the second motor, and the power battery is subjected to oscillation heating. The power battery is oscillated and heated by using the windings of the two inherent motors and the two bridge arm converters of the automobile, so that the effect is better, the efficiency is higher, other external equipment does not need to be additionally arranged, and the cost is saved.
