Problems solved by technology

[0004] Although the prior art discloses a variety of technologies for cooling the motor and power battery in an electric vehicle, and in some instances this cooling system is integrated with the vehicle's passenger compartment HVAC system (HVAC is an abbreviation for Heating, Ventilation and Air Conditioning) combination, but the combination system is still relatively complex, and the thermal management efficiency is low. In actual design, it is expected to further simplify the system and improve system efficiency

Abstract

The invention discloses a new energy vehicle thermal management system. The new energy vehicle thermal management system comprises a first cooling circuit, a second cooling circuit, a third cooling circuit, a fourth cooling circuit and a fifth cooling circuit. The new energy vehicle thermal management system has five circulation modes, and effective cooling and heating of ternary lithium batteriescan be satisfied so that the maximum property is given to full play; thermal management efficiency is improved; and the system structure is simplified. The invention further discloses a battery electric vehicle.

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...
