Cooling system of electric power system for vehicle

Disclosed is a cooling system for an electric power system for a vehicle capable of selectively cooling a power component used while the vehicle travels or is charged.

Traction battery self-heating control method and device

Disclosed is a traction battery self-heating control method and a device. Acquiring a second temperature of a rotor at a current sampling time according to system parameters and a first temperature of the rotor at a previous sampling time, and estimating a third temperature of the rotor at a next sampling time according to the first temperature and the second temperature, and stopping the self-heating of the traction battery when the third temperature reaches a demagnetization temperature of the rotor. Whether to stop the self-heating of the traction battery is determined by estimating a rotor temperature under the self-heating condition, and comparing the rotor temperature with the demagnetization temperature of the rotor, and thus the self-heating control of the traction battery is realized.

Motor, control method, power system, and electric vehicle

Disclosed is a motor, a control method, a power system, and an electric vehicle. Each phase stator winding of the motor includes two sub-winding sets. When a traction battery needs to be heated, the two sub-winding sets of the motor store electrical energy and provide alternating currents to the traction battery through an inverter, so that the traction battery uses its internal resistance for heating. In addition, the two sub-winding sets generate opposite magnetic fields which cancel each other out, so that the strength of the magnetic field inside each phase stator winding and the air gap magnetic flux are reduced, thereby alleviating the heat generation and NVH problems of the motor.
