Description

technical field [0001] The invention relates to an electromechanical energy converter with dual mechanical ports, belonging to the technical field of motors. Background technique [0002] The goal of hybrid electric vehicle control is to make the engine work independently of the load and always work near the best efficiency point, so as to improve fuel efficiency, reduce emissions, or use electric energy as auxiliary energy to enhance the power performance of the vehicle. The ordinary hybrid power transmission system divides the power from the internal combustion engine into two paths: mechanical power and electronic power through a special power distribution device, which can take advantage of the advantages of series and parallel hybrid power transmission systems; but the structure is complex and costly. High, while too many gears reduce efficiency. [0003] The dual mechanical port electromechanical energy converter has two rotors, that is, two mechanical shafts, which c...
