Vehicle thermal management system and vehicle

Abstract

The invention relates to a vehicle thermal management system and a vehicle. The vehicle heat management system comprises an air conditioning system, a battery and electric drive heat management systemand a heat exchanger. The heat exchanger is simultaneously arranged in the air conditioning system and the battery and electric drive heat management system; the battery and electric drive heat management system comprises a first cooling liquid flow path, a second cooling liquid flow path and a four-way valve, a heat exchanger, a power battery and a first water pump are arranged on the first cooling liquid flow path, one end of the first cooling liquid flow path is connected with a port A of the four-way valve, and the other end of the first cooling liquid flow path is connected with a port Bof the four-way valve; an electric controller, a charger and a second water pump are arranged on the second cooling liquid flow path, one end of the second cooling liquid flow path is connected witha port C of the four-way valve, and the other end of the second cooling liquid flow path is connected with a port D of the four-way valve. Thus, when the port A and the port C of the four-way valve are connected and the port B and the port D of the four-way valve are connected, heat generated by the charger and the electric controller can heat the power battery, heat dissipation of the charger andthe electric controller and heating of the power battery are met at the same time, and the energy utilization rate of the whole vehicle is increased.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle manufacturing, and in particular, to a vehicle thermal management system and a vehicle using the vehicle thermal management system. Background technique [0002] The vehicle thermal management system includes three major systems: the air-conditioning thermal management system, the battery thermal management system and the electric drive thermal management system. The existing electric drive thermal management system is independent of the air-conditioning thermal management system and the battery thermal management system. When the vehicle is charging at low temperature, the electric control and the charger will generate heat. It is necessary to turn on the radiator in the electric drive thermal management system to At the same time, in the battery thermal management system, it is necessary to turn on the heater to heat the battery so that the battery has a suitable working temperature.

Problems solved by technology

The existing electric drive thermal management system is independent of the air-conditioning thermal management system and the battery thermal management system. When the vehicle is charged at low temperature, the electric control and charger will generate heat. It is necessary to turn on the radiator in the electric drive thermal management system to At the same time, in the battery thermal management system, it is necessary to turn on the heater to heat the battery so that the battery has a suitable working temperature. Obviously, the heat collection planning of the vehicle thermal management system is unreasonable, resulting in energy waste of
