Description

technical field

[0001] The present application relates to the technical field of hybrid electric vehicles, in particular to a heat management system for hybrid electric vehicles. Background technique

[0002] There are technical bottlenecks in electric vehicles at the present stage, and electric vehicle users are faced with the problems of charging anxiety and mileage anxiety. Compared with pure electric vehicle solutions, hybrid vehicles are a very effective way to realize clean transportation and solve the anxiety of electric vehicle users at this stage. Advantageous new energy vehicle solutions.

[0003] The core of the hybrid technology is to complement each other through the motor and the engine, 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 electric vehicle system solution can increase energy recovery technology, etc., which significantly improves the energy ...
