Provided are a control method for a battery heating system, a battery heating system, and an electric vehicle. The battery heating system includes a supercapacitor and a pulse control unit. The control method includes: obtaining a temperature value and an SOC value of a power battery; and issuing a heating instruction to the pulse control unit when the temperature value is lower than a predetermined temperature threshold and the SOC value is higher than a predetermined charge threshold, to allow the pulse control unit to control, based on the heating instruction, bi-directional energy flow between the power battery and the supercapacitor by means of a pulse current, to heat the power battery.
