Description

technical field [0001] The present application relates to the technical field of hybrid electric vehicles, in particular to a thermal management system for hybrid electric vehicles. Background technique [0002] At this stage, there are technical bottlenecks in electric vehicles, and electric vehicle users are faced with the problems of charging anxiety and cruising range anxiety. Compared with pure electric vehicle solutions, hybrid electric vehicles are a great way to achieve clean transportation and solve the anxiety of electric vehicle users at this stage. Advantages of new energy vehicle solutions. [0003] The core of hybrid technology is that the motor and the engine complement each other, learn from each other, and match each other so that the car engine can run in a high-efficiency range for a long time. In addition, when braking, the hybrid vehicle system solution can add energy recovery technology, etc., which significantly improves the energy efficiency of the e...
