New energy vehicle integrated thermal management system and working method thereof

Abstract

The invention discloses a new energy vehicle integrated heat management system and a working method thereof, and the system comprises a warm core heating system for providing a heat source, a refrigerant circulating system for conveying a refrigerant for heat exchange, an evaporative cooling system for providing a cold source, and a circulating heat exchange system for heat exchange; the circulating heat exchange system is provided with a first heat exchanger and exchanges heat with the evaporative cooling system and the warm core heating system through the first heat exchanger. According to the invention, by controlling opening and closing of valves inside all the systems and among the systems, cooling of the battery, the electric control equipment and the passenger compartment under therefrigeration working condition, heating of the passenger compartment under the heating working condition, preheating, heat preservation and waste heat recovery of the battery and the electric controlequipment are achieved, automatic driving and wireless charging modules are incorporated into the heat management system, the waste heat utilization rate is high, the energy-saving effect is good, the cost is reduced, the heat pump mode and the working temperature requirement of the electric heat pump type compressor are low, and the low-temperature working condition using requirement is met.

Description

technical field [0001] The invention relates to the technical field of vehicle thermal management, in particular to a new energy vehicle integrated thermal management system and a working method thereof. Background technique [0002] Nowadays, with the gradual popularization of electric vehicles, the problems they face have gradually become prominent. Compared with traditional vehicles, new energy vehicles have no engine heat source, and rely on electric heating for heating, which consumes a lot of energy. At the same time, the battery is discharged under low temperature conditions. The efficiency is low, and the battery temperature is too high in summer and it is easy to spontaneously ignite, and it will also cause problems with charge and discharge efficiency. [0003] At present, the heating and battery heating of electric vehicles mainly adopt electric heating solutions. The efficiency of electric heating is low, and the cruising range of electric vehicles is greatly re...
