Abstract

The invention discloses a thermal management coupling system of a pure electric vehicle, comprising a motor cooling system, a battery thermal management system and an air conditioning system, a first coupling pipeline is connected between the air conditioning system and the motor cooling system, the motor cooling system and the battery thermal There is a second coupling pipeline connected between the management systems, the first coupling pipeline is connected with the first coupling pipeline control solenoid valve that can control its on and off, and the second coupling pipeline is connected with a control solenoid valve that can control its on and off The second coupling line controls the solenoid valve. By coupling the air conditioning system, the battery thermal management system and the motor cooling system, the heat of the three systems of the vehicle can be fully utilized, reducing the demand for battery energy for cooling or heating of a single system during operation. Through the structure of two-way solenoid valve, three-way solenoid valve and two stop valves, the separate control and overall control of the three systems are realized.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a heat management coupling system for pure electric vehicles. Background technique [0002] The cooling system of a pure electric vehicle generally consists of a motor cooling system, a battery thermal management system and an air conditioning system. At present, many technologies on pure electric vehicles are still in the exploratory stage, and the three cooling systems are often designed independently without affecting each other, wasting a lot of potential energy. As the only energy source for pure electric vehicles, the battery's operating status directly affects the performance of the vehicle. Due to the complex operating conditions of pure electric vehicles, batteries have to withstand harsh working environments such as high temperature and low temperature. Studies have shown that batteries are more sensitive to the temperature of the working environment....
