Abstract

The embodiments of the present application provide a current modulation module, a parameter determination module, a battery heating system, as well as a control method and a control device thereof, and relate to the field of battery. The control method includes determining a state of charge (SOC), of the battery, modulating a first current flowing into windings of a motor into an alternating current when the SOC is greater than a first SOC threshold, so as to use heat generated by the alternating current in a first target module to heat the battery, and modulating a second current flowing into the windings of the motor into a direct current when the SOC is less than or equal to the first SOC threshold, so as to use heat generated by the direct current in a second target module to heat the battery.
