[0063] The hydrogen subsystem, air subsystem, electrical subsystem and thermal management subsystem are systems that can operate independently and are equipped with their own independent human-computer interaction software.

[0064] Working principle:

[0065] See also Figure 1 When the transmission joint control system is jointly regulated, the hydrogen subsystem, air subsystem, electrical subsystem and thermal management subsystem are connected through hydrogen delivery pipelines, air delivery pipelines and water circulation pipelines respectively. The electrical energy generated by the electrochemical reaction of the fuel cell stack is stored and discharged through the power line of the electrical system. The system uses CAN bus for communication.

[0066] See also Figure 2 In the hydrogen subsystem, the hydrogen bottle controls the amount of hydrogen intake through the solenoid valve and regulating valve control module inside the hydrogen inlet module, and adjusts and sets the hydrogen intake pressure to provide the hydrogen required for the reaction of the anode of the fuel cell stack. The stack is composed of multiple fuel cell units. The hydrogen at the anode and the oxygen at the cathode react electrochemically in the stack to generate electricity. After the anode tail gas in the stack passes through the water-gas separator of the hydrogen exhaust module, the recyclable hydrogen is sent to the hydrogen circulation module, and the excess water gas is discharged from the system. The hydrogen circulation module pumps the unreacted hydrogen at the anode into the stack again to improve the utilization rate of hydrogen while ensuring system safety.

[0067] See also Figure 3In the air subsystem, the air quality control module filters the impurities in the air from the outside air to ensure the performance of the fuel cell, and measures the air mass flow entering the system. The filtered air is compressed and pressurized by the air compressor to reach the pressure required for entering the fuel cell stack reaction. If the compressed air temperature is too high, the high-pressure air is cooled by the intercooler to ensure that the gas enters the fuel cell stack at a suitable temperature to avoid damage to the fuel cell stack caused by excessive temperature. The cooled air is humidified by the humidifier to ensure that the air enters the fuel cell stack in the hydrogen subsystem with a certain humidity, so that the fuel cells in the fuel cell stack can perform electrochemical reactions within a reasonable humidity range, improve the output power and stability, and extend the service life of the battery. The humidified air enters the gas humidification tank, which is mainly used to simulate the environment of the cathode (i.e., air side) tail gas after the fuel cell stack reaction in the hydrogen subsystem. After the electrochemical reaction of the fuel cell, water will be generated at the cathode. The cathode tail gas with a certain humidity will flow back to the humidifier again to humidify the air before entering the stack, and then be discharged from the system.

[0068] like Figure 4 As shown in the figure, in the electrical subsystem, in terms of power supply, when the DC adjustable power supply works independently, it can simulate the power generation of the fuel cell stack in the battery stack to provide DC power for the entire system. The DC transformer stabilizes the voltage of the DC adjustable power supply and converts the required voltage to power the electronic load or charge the lithium battery. The lithium battery stores the system's electrical energy, including the electrical energy generated by the battery stack during joint commissioning. The electronic load provides a load that consumes electrical energy when the system is working under load.

[0069] In terms of CAN communication, controller (FCU): FCU is the controller of the system. Its function is to receive control instructions, coordinate the work of other actuators, and monitor the sensor status and diagnose system failures in real time. Since each subsystem is equipped with matching professional human-computer interaction software, this software can quickly set different parameters in the system through the host computer and monitor sensor data in real time.

[0070] like Figure 5 As shown, in the thermal management subsystem, the radiator cools the circulating water by exchanging heat with the outside cold air, and the cooling circulating water is pumped into the heating modules in each subsystem that needs to be cooled by a water pump, thereby achieving the effect of cooling the heating elements.

[0071] When the thermal management subsystem needs to operate independently, the heater is used to simulate the heating element, and the cooling circulating water is mainly used to cool these heating elements. The thermostat can adjust the water inflow and flow path of the cooling circulating water into the radiator, thereby controlling the cooling water circulation range and adjusting the cooling system's heat dissipation capacity to ensure that the heating element operates within the appropriate temperature range. The water supply tank is used to ensure sufficient circulating cooling water.
