The present application relates to the field of fuel cell vehicles, in particular to a method for controlling a fuel cell stack cooling system and a fuel cell controller. The fuel cell stack cooling system control method includes: respectively calculating the target rotation speed value of the cooling water pump, the opening target value of the electronic thermostat, and the target rotation speed value of the cooling fan, and controlling the rotation speed of the cooling water pump and the opening of the electronic thermostat. The temperature and the speed of the cooling fan approach the target speed of the cooling water pump, the target opening of the electronic thermostat and the target speed of the cooling fan. The method provided by this application can reduce the fluctuation of the stack temperature through the control of the components of the stack cooling system, thereby improving the power generation efficiency of the stack, avoiding frequent start and stop of related components, improving the reliability of the entire system, and extending the stack life. life.
Description
technical field [0001] The present application relates to the field of fuel cell vehicles, in particular to a method for controlling a fuel cell stack cooling system and a fuel cell controller. Background technique [0002] In recent years, new energy vehicles have developed rapidly, and fuel cell vehicles have made great progress. The working principle of fuel cell vehicles is that hydrogen fuel and oxygen undergo redox reactions to generate electric energy to drive the motor. The chemical reaction process of fuel cells will not produce harmful products, and its energy conversion efficiency is 2 to 3 times higher than that of internal combustion engines. Therefore, from the perspective of energy In terms of utilization and environmental protection, fuel cell vehicles are an ideal vehicle. With the advancement of technology and the needs of product promotion, the fuel cell system has changed from auxiliary power battery-driven vehicles to vehicles mainly driven by fuel cell...
