Abstract: A motor driving system includes a heating controller, a motor controller connected to the heating controller, and a driving motor connected to the heating controller and the motor controller. The heating controller is configured to: generate a plurality of pulse width modulation (PWM) signals in response to detecting that a vehicle is in a parked state and in response to receiving a heating request initiated by an apparatus, and output the PWM signals to the motor controller to control the motor controller to output an alternating current to a stator of the driving motor. The stator and a rotor of the driving motor generate heat in a static state and conduct the heat to the apparatus.

Abstract: An energy processing apparatus for a battery includes an inverter, an energy storage circuit, and a controller. A first terminal of the inverter is connected to the battery. A first terminal of the energy storage circuit is connected to an external power supply device, and a second terminal of the energy storage circuit is connected to a second terminal of the inverter. The controller is connected to a third terminal of the inverter. In a first state, the controller controls the inverter to enable the energy storage circuit to be charged or discharged by the battery to self-heat the battery. In a second state, at least a part of the energy storage circuit and at least a part of the inverter form an adaptive voltage charger, and the controller controls the adaptive voltage charger to charge the battery.

Abstract: A method for controlling heating of an electric drive system of a vehicle, the electric drive system includes a motor controller and a motor, and the method includes: determining that the vehicle is in a travelling state; obtaining a rotation speed value and a torque control value of a motor and obtaining a carrier instruction value of a motor controller when receiving a heating instruction; obtaining a first current instruction value based on the rotation speed value and the torque control value, and obtaining a second current instruction value based on the torque control value and the first current instruction value; adjusting a control signal of the motor controller based on at least one of the second current instruction value or a second carrier frequency; and controlling the motor to operate based on the adjusted control signal, so that the electric drive system generates heat.
