A FUEL CELL VEHICLE THERMAL MANAGEMENT SYSTEM WITH COLD START FUNCTION AND CONTROL METHOD THEREOF

A fuel cell vehicle thermal management system with cold start function, which includes a fuel cell stack, an electronic water pump, an electronic thermostat, a cold start heater, a first solenoid valve, a thermal management controller, and the air intake preheating heat exchangers. The electronic water pump, electronic thermostat, cold start heater, and the first solenoid valve are all electrically connected to the thermal management controller. The coolant outlet of the fuel cell stack is connected with the liquid inlet of the electronic water pump, and the liquid outlet of the electronic water pump is connected with the liquid inlet of the electronic thermostat and the liquid inlet of the first solenoid valve. The first liquid outlet of the electronic thermostat is connected with the liquid inlet of the cold start heater. The liquid outlet of the cold start heater is connected with the liquid inlet of the fuel cell stack. The liquid outlet of the first solenoid valve is connected with the liquid inlet of the intake preheating heat exchanger. The liquid outlet of the intake preheating heat exchanger is connected with the liquid inlet of the cold start heater. The invention solves the problems of the cold start of the fuel cell vehicle in a low temperature environment and the preheating of cold air before entering the stack.
