The invention discloses an electric vehicle thermal management system and method based on R290 gas supplementing and enthalpy increasing, and relates to the technical field of electric vehicles. Comprising a power battery, a compressor, a heat exchanger, a water cooling condenser, a first electronic expansion valve, a second electronic expansion valve, a first water pump, a second water pump, a third water pump, a ten-way valve, a low-temperature radiator, an air conditioner assembly, a first three-way proportional valve, a second three-way proportional valve, a motor and an electric controller. R290 is used as a refrigerant, the influence of the system on the environment can be reduced, the negative influence on global warming and ozone depletion is reduced, meanwhile, the adopted air-supplementing enthalpy-increasing technology can help the system to keep a stable operation state under different working conditions, the stability and reliability of the system are improved, and the system is suitable for large-scale popularization and application. And the thermal management system can work normally under various conditions.

    本发明公开了一种基于R290补气增焓的电动汽车热管理系统及方法,涉及电动汽车技术领域,包括动力电池、压缩机、换热器、水冷冷凝器、第一电子膨胀阀、第二电子膨胀阀、第一水泵、第二水泵、第三水泵、十通阀、低温散热器、空调总成、第一三通比例阀、第二三通比例阀、电机以及电控器。本发明利用R290作为制冷剂,可以降低系统对环境的影响,减少对全球变暖和臭氧层破坏的负面影响,同时,采用的补气增焓技术可以帮助系统在不同工况下保持稳定的运行状态,提高系统的稳定性和可靠性,确保热管理系统在各种情况下都能够正常工作。
