Abstract

The invention relates to a pure electric vehicle cooling system and a battery electric vehicle including same. The cooling system comprises an electric drive system cooling circuit, an air-conditioning system loop and a power battery system cooling circuit. The cooling system also comprises a four-way control valve connected between the electric drive system cooling circuit and the power battery system cooling circuit and used to switch over on-off of the electric drive system cooling circuit and the power battery system cooling circuit, and a three-way control valve used to control heat exchange between the power battery system cooling circuit and the air-conditioning system loop in the power battery system cooling circuit. A heat exchange device between the electric drive system coolingcircuit and the air-conditioning system loop forms a water-cooled condenser of the air-conditioning system loop. A heat exchange device between the power battery system cooling circuit and the air-conditioning system loop forms a low-temperature cooler used for the power battery system cooling circuit. A heat exchanger module in the system is simple in structure and low in correlative influence, and fully develops cooling performance and preferably improves environment adaptability of a whole vehicle.

Description

technical field [0001] The present invention relates to the technical field of thermal management of pure electric vehicles; in particular, the present invention relates to a cooling system for pure electric vehicles, and further relates to a pure electric vehicle including the cooling system. Background technique [0002] With the continuous development of the new energy industry, major automakers have gradually increased investment in research and development of pure electric vehicles. [0003] Motors, batteries, etc. are the power drive systems of pure electric vehicles, and their performance determines the performance of the entire vehicle. It is one of the key technologies in the development of pure electric vehicles to ensure that the power drive system works in a suitable temperature range so that it can perform at its best. Therefore, the powertrain system of pure electric vehicles needs to match the corresponding cooling system. [0004] At present, matching the c...
