Abstract

The invention discloses a thermal management system of an electric vehicle, which comprises a vehicle-mounted charger, a controller, a four-way valve, a first motor, a second motor, a three-way valve, a heat dissipation assembly and a first water pump, and is characterized in that the first motor is provided with a first heat dissipation flow channel, and the second motor is provided with a second heat dissipation flow channel; the vehicle-mounted charger, the controller, the four-way valve, the first heat dissipation flow channel, the second heat dissipation flow channel, the three-way valve, the heat dissipation assembly and the first water pump are specifically connected through water pipes to form heat dissipation waterway circulation. And the controller is configured to realize heat dissipation through an auxiliary heat dissipation mode, an alternate heat dissipation mode and a dual heat dissipation mode. According to the thermal management system of the electric vehicle provided by the embodiment of the invention, the final heat dissipation effect is improved by constructing a specific heat dissipation system structure.

Description

technical field [0001] The invention relates to the technical field of vehicle heat dissipation, in particular to a thermal management system of an electric vehicle. Background technique [0002] With the continuous development of new energy technologies, electric vehicles are gradually recognized by the market and favored by consumers due to their advantages such as quick start, zero emission, low noise, and low energy consumption. [0003] For electric vehicles, the heat dissipation capability is particularly important. If key devices such as on-board chargers are not well dissipated, the service life of the on-board charger will be reduced, and the normal driving of the electric vehicle will be adversely affected. [0004] In the prior art, the on-board charger dissipates heat through a cooling circuit formed by a single motor, which leads to high energy consumption of the motor and the cooling water pump, and the heat dissipation effect is difficult to meet expectations,...
