The invention discloses a battery heating circuit, system and method, and relates to the field of vehicles. According to the specific implementation scheme, at least one driving resistor array comprises at least two parallel branches, each parallel branch comprises a resistor and a switch which are connected in series, or each parallel branch except one parallel branch only comprises a resistor and a switch which are connected in series in the at least two parallel branches; in two parallel ends of the at least two parallel branches, one end is used for accessing a driving signal, and the other end is used for being connected with a grid electrode of an insulated gate bipolar transistor in an electric driving system of the vehicle; the detection end of the heating control module is used for being connected with equipment for detecting the temperature of a power battery of the vehicle, and the control end of the heating control module is connected with the at least one driving resistor array so as to control switching-on and switching-off of the switch. According to the invention, the loss of the IGBT device can be changed by changing the grid input resistance of the IGBT device of the electric driving system, and the heating efficiency of the battery is adjusted.
