Abstract

The invention discloses a vehicle thermal management system and method based on a hybrid electric vehicle. The system includes compressors, expanders, heat exchangers, water tanks, pumps, radiators, engines, valves and other components. , can adjust different operating modes, realize the combination of battery management, waste heat recovery, and air conditioning / heat pump system, meet the cooling and heating requirements of air conditioning, heat dissipation and preheating of the engine and battery, each working condition does not affect each other, and can be used independently Completed, the present invention meets the waste heat recovery and simultaneously realizes the demand for cooling / heating and the refrigeration and cooling battery pack of the air conditioning / heat pump system by coupling the waste heat recovery system and the air conditioning / heat pump system, the air conditioning / heat pump system and the battery management system at the same time, Meet the thermal management requirements of hybrid vehicles under different driving conditions. The whole system is highly integrated and applicable to various working conditions, which can effectively improve the energy utilization efficiency of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of thermal management of hybrid electric vehicles, and in particular relates to a thermal management system and method for a complete vehicle based on hybrid electric vehicles. Background technique [0002] In recent years, countries around the world have become more and more strict on environmental protection. Hybrid vehicles have become a focus of automobile development and research due to their advantages of energy saving and low emissions, and have begun to be commercialized. The core of this technology is to learn from each other and match each other under different working conditions, so that the car can run in the high-efficiency range for a long time, and at the same time, it takes advantage of the long-term continuous working time of the engine, the advantages of good power and the pollution-free electric motor. The advantage of low noise. Engine waste heat recovery technology is also being continu...
