Title:
ENERGY CONVERSION DEVICE AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/093801
Kind Code:
A1
Abstract:
An energy conversion device and a vehicle. The energy conversion device comprises: an electric motor (10), an electronic control (20), a traction battery (30) and a controller (40). The controller (40) is configured to control all bridge arms (21) corresponding to windings of the electric motor (10), so that the collaboration of driving and battery self-heating is achieved, and the crest and trough of an actual N-line current flowing through an N line of the electric motor counteract or are superposed with the crest and trough of an actual phase current flowing through each phase of winding of the electric motor (10), thus reducing or increasing the amplitudes of the actual phase current of each phase of winding at the crest and trough, and thereby providing a greater phase current for the electric motor (10) so as to drive the electric motor (10). Thus, the torque output by the electric motor (10) is greater, thereby improving the dynamic performance of the whole vehicle or increasing the quantity of heat production of an electric drive system.
