Title:
ELECTRIC-DRIVE ACTIVE HEATING CONTROL METHOD, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/174191
Kind Code:
A1
Abstract:
An electric-drive active heating control method. The method comprises: S101, acquiring electric motor parameters of a drive electric motor in an electric drive system; S102, determining a target exciting current according to the electric motor parameters and a preset electric motor torque algorithm, wherein under the action of the target exciting current, an output torque of the drive electric motor meets a preset condition; and S103, determining a three-phase current of the drive electric motor according to the target exciting current, a preset torque current and the current rotor position. Further disclosed are an electric-drive active heating control apparatus, an electronic device and an electric vehicle. A target exciting current is controlled by means of a preset electric motor torque algorithm, and a preset torque current is controlled, so that a three-phase current is redistributed, and an output torque of an electric motor is zero when neither of the target exciting current and the preset torque current is zero; and since the heating power of the electric motor is in direct proportion to the square of the current thereof, the total heating power of the electric motor is improved.
