Abstract

The invention discloses a fuel cell vehicle thermal management system, method, storage medium and vehicle. The system comprises: a liquid inlet of a first electronic water pump is connected to a liquid outlet of a fuel cell, and the liquid outlet is connected to a first three-way valve for liquid inlet. The first liquid outlet of the first three-way valve is connected to the liquid inlet of the heater, the liquid outlet of the heater is connected to the liquid inlet of the second three-way valve, and the first liquid outlet of the second three-way valve is connected to the fuel cell. The liquid port is connected, the second liquid outlet is connected with the liquid inlet port of the second electronic water pump, the liquid outlet port of the second electronic water pump is connected with the liquid inlet port of the air conditioner heater heat exchanger, and the liquid outlet port of the air conditioner heater heat exchanger is connected with the fuel cell The liquid inlet is connected; the first electronic water pump, the first three-way valve, the heater, the second three-way valve, and the second electronic water pump are all connected to the controller with electric signals. In the present invention, the controller controls the action of each three-way valve, electronic thermostat, heater, water pump, and fan to realize different circulation loops of the cooling liquid after collecting and analyzing the data collected by the sensor.

Description

technical field [0001] The invention relates to the field of fuel cell control, in particular to a fuel cell vehicle thermal management system, method, storage medium and vehicle. Background technique [0002] Fuel cell vehicles, as a new energy vehicle with reduced oil consumption, high energy conversion rate, and zero emissions, are considered to be an important way to solve the energy crisis and environmental degradation. Countries around the world are actively developing hydrogen energy and fuel cell technologies [0003] When the temperature inside the fuel cell is below freezing point, the water in the fuel cell freezes. Before the temperature in the battery rises to zero, if the water in the catalytic layer freezes, the electrochemical reaction will be terminated due to the freezing of water in the reaction area, and the expansion of the water will damage the structure of the fuel cell stack. The problem of fuel cell water freezing will reduce the performance and lif...
