Embodiment 1

[0032] Such as figure 1 , figure 2 , image 3 As shown, the electric vehicle thermal management system provided by Embodiment 1 of the present invention includes an air conditioning circuit, a motor cooling circuit and a battery cooling circuit, the motor cooling circuit is used to cool the motor 2 and related power components 3, and the battery cooling circuit is used to cool the power battery pack1. The battery cooling circuit is connected to the air conditioning circuit, and the air conditioning circuit and the motor cooling circuit are independent of each other.

[0033] This embodiment improves the thermal management system of the existing electric vehicle, integrates the battery cooling circuit and the air conditioning circuit, and uses the refrigerant phase change method instead of the water cooling method to cool the power battery pack 1, eliminating the need for cooling. The water circuit structure of the power battery pack reduces the components of the battery co...

Abstract

The invention discloses an electric vehicle thermal management system, belonging to the technical field of electric vehicles, comprising an air conditioning circuit and a motor cooling circuit, the motor cooling circuit is used for cooling the motor and power components, and also includes a battery cooling circuit used for cooling a power battery pack, The battery cooling circuit is connected to the air conditioning circuit, and the air conditioning circuit and the motor cooling circuit are independent of each other. The electric vehicle thermal management system provided by the invention improves the thermal management system of the existing electric vehicle, sets the battery cooling circuit and the air conditioning circuit into an integrated structure, and saves the water circulation structure for cooling the power battery pack. The components of the battery cooling circuit are greatly reduced, the overall weight of the electric vehicle is effectively reduced, and it is beneficial to optimize the electric vehicle and reduce the ineffective power consumption when the electric vehicle is running.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a heat management system for electric vehicles. Background technique [0002] An electric vehicle refers to a vehicle that is powered by a vehicle-mounted power supply and uses a motor to drive the wheels. Because the impact of electric vehicles on the environment is much smaller than that of traditional vehicles, the prospect of electric vehicles is widely optimistic, but the technology of electric vehicles is still immature. In order to ensure the mileage and speed of electric vehicles, the battery packs equipped with electric vehicles must have a certain storage capacity and power supply capacity. During the driving of an electric vehicle, the battery pack continues to work and generate heat. Therefore, the thermal management of the battery pack needs to be fully considered when designing an electric vehicle. [0003] At present, the thermal management system of an...
