The invention provides a safety control system for a fuel cell vehicle, which includes a controller, a hydrogen assembly, a detection assembly and a trigger assembly, the detection assembly is electrically connected to the controller through the trigger assembly, and the detection assembly is also directly electrically connected to the controller. The controller is electrically connected to the hydrogen component, the controller is in a dormant state, the detection component and the trigger component operate at mW level power, the detection component detects whether the hydrogen component is abnormal, and the detection component sends a trigger signal to the controller through the trigger component when detecting an abnormality The controller is woken up, the controller obtains the detection value from the detection component, and the controller executes the preset safety instruction according to the value detected by the detection component. The advantage of this safety control system is that the controller can also perform safety operations and judge whether the sensor signal is normal even when it is not in the normal power mode, thereby improving the energy utilization rate and safety level.
Description
technical field [0001] The invention relates to the field of fuel cell vehicle control, in particular to a safety control system for a fuel cell vehicle. Background technique [0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy generated by the reaction of hydrogen and oxygen into electrical energy through an electrochemical reaction. It has the advantages of high power generation efficiency and low environmental pollution, so it is widely used in the automotive field. The hydrogen storage and supply system, as the fuel storage and supply device for the on-board fuel cell engine, is an indispensable part in the development of hydrogen energy vehicles and plays a very important role. The safety level of the hydrogen storage and supply system restricts the development and progress of the overall safety of hydrogen energy vehicles. [0003] At present, when a hydrogen fuel cell vehicle is in a stationary state, a hydrogenation s...
