The invention discloses a controller and a control method of a vehicle-mounted hydrogen supply system. In the controller of the vehicle-mounted hydrogen supply system, the input end of a signal acquisition module is connected with the vehicle-mounted hydrogen supply system, the output end of the signal acquisition module is connected with a microprocessor, and the signal acquisition module is usedfor acquiring data information of the vehicle-mounted hydrogen supply system and sending the data information to the microprocessor; the microprocessor generates a first control instruction accordingto the data information; the microprocessor is connected with the first bus transceiving module and is used for sending the data information to the automobile electronic controller, receiving a second control instruction sent by the automobile electronic controller and sending the second control instruction to the control module; the input end of the control module is connected with the microprocessor, and the output end of the control module is connected with all electromagnetic valves of the vehicle-mounted hydrogen supply system and used for controlling all the electromagnetic valves to act according to the first control instruction and the second control instruction. By implementing the invention, the running state of the vehicle-mounted hydrogen supply system is continuously monitored and controlled, and the whole vehicle-mounted hydrogen supply system is ensured to be in a safe, reliable and stable running state.
Description
technical field [0001] The invention relates to the technical field of hydrogen energy vehicle measurement and control equipment, in particular to a controller and a control method for a vehicle-mounted hydrogen supply system. Background technique [0002] Under the dual pressure of energy and environment, fuel cell vehicles have become the direction of the future development of the automobile industry and the focus of research in the field of automobiles. A fuel cell vehicle is a vehicle powered by electricity generated by an on-board fuel cell device. The fuel used by the vehicle-mounted fuel cell device is high-purity hydrogen or hydrogen-containing reformed gas obtained by reforming hydrogen-containing fuel. At present, most of the fuel cell hydrogen supply systems for vehicles use 35MPa or 70MPa high-pressure gaseous hydrogen storage, and then supply the stack through two or more stages of decompression to a suitable pressure range. The on-board hydrogen supply system...
