Abstract

The invention provides a power coupling system and a control method thereof for an electric automobile. The power coupling system for the electric automobile comprises an engine (10), a generator (11), a clutch (20) and a driving motor (12), wherein the generator (11) is coaxially connected with the engine (10); the clutch (20) is arranged between the engine (10) and the generator (11); the driving motor (12) is separately connected with the clutch (20) and a differential (30) through a transmission device. According to the power coupling system for the electric automobile, disclosed by the embodiment of the invention, all components are reasonably distributed, the structure is compact, assembly is facilitated, space is saved, and the utilization rate of the space in the automobile is increased.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to an electric vehicle power coupling system and a control method thereof. Background technique [0002] With the lack of oil resources and the improvement of people's awareness of environmental protection, there is an urgent need for energy-saving and low-emission or even zero-emission green and environmentally friendly automotive products. To this end, governments around the world and major automakers are intensifying efforts to develop various types of electric vehicles. Compared with traditional internal combustion engines, electric vehicle traction motors have a wider operating range, and the characteristics of constant torque at low speed and constant power at high speed are more suitable for vehicle operation requirements. In recent years, the power drive system and its working mode for electric vehicles have become a research hotspot. [0003] However, due to the involve...
