Abstract

The invention discloses a heat management system for an electric vehicle, which includes a cooling liquid storage tank, a heat exchanger and an expansion valve, wherein the liquid outlet of the cooling liquid storage tank is respectively connected to the motor, the power battery and the motor controller through corresponding pipelines. The liquid inlet of the motor, the power battery and the motor controller are all connected to the liquid inlet of the coolant storage tank through pipes, and the liquid outlet of the motor is also connected to the liquid inlet of the power battery through the return pipe. A flow regulating solenoid valve is also installed on the pipe; the exchange liquid outlet of the cooling liquid storage tank communicates with the exchange liquid inlet of the cooling liquid storage tank through a heat exchanger and an expansion valve. The automobile thermal management system proposed by the invention has a simple structure and principle, and has good energy-saving and emission-reduction effects.

Description

technical field [0001] The invention relates to the technical field of automobile heat management, in particular to an electric automobile heat management system and a control method thereof. Background technique [0002] New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. The efficiency of the thermal management system largely depends on the optimal control strategy of the system. The control objects include the speed of the water pump, the opening of the electronically controlled thermostat valve, and the speed of the cooling fan. The current automotive thermal management system has a complex structure and principle, and the effect of energy saving and emission reduction is poor. Contents of the invention [0003] The main purpose of the present invention is to provide a thermal management system and a control method for an electric ve...
