Description

technical field

[0001] The invention belongs to the technical field of new energy vehicles. Specifically, the invention relates to a thermal management system of a new energy vehicle and a pure electric vehicle. Background technique

[0002] As national policies and regulations become more and more stringent on environmental protection, the state encourages auto companies to develop new energy vehicles, and there are corresponding subsidies, otherwise they will even face penalties. Pure electric passenger vehicles, as a type of new energy vehicles, are favored by many companies due to their zero emissions, low cost of use, and good market prospects.

[0003] As customers have higher and higher requirements for electric vehicles, especially for the battery life of electric vehicles, in order to meet the development of electric vehicles with higher battery life, the current mainstream trend in the market is to use ternary lithium batteries as Power batteries, and due to the h...
