The device comprises a hydrogen storage bottle, a pipeline and the like, wherein a bottle valve is additionally arranged at the broken end of the hydrogen storage bottle, and the bottle valve is formed by integrating a main shut-off valve, a Pressure Release Device (PRD), a temperature sensor and a manual shut-off valve as shown in figure 1. The main shutoff valve is operated in an electric mode and is an electromagnetic valve, the electromagnetic valve is in an automatic closing state when the electromagnetic valve is powered off and is used for controlling hydrogen supply, the manual shutoff valve is used for manually closing the bottle valve, and after the manual shutoff valve is closed, the hydrogen storage bottle can not supply hydrogen in the opening state of the electromagnetic valve.

A flow chart of a method of detecting a cylinder valve opening failure is shown in fig. 4. The basic idea is as follows: when the bottle valve is opened, the rated working current of the electromagnetic valve is I, and if the electromagnetic valve fails and can not be opened, the driving current of the electromagnetic valve is 0 or far smaller than the rated working current I, so that when the hydrogen of the fuel cell is supplied, the electromagnetic valves in all the bottle valves in the hydrogen system can be sequentially opened in a short time, meanwhile, the current sensor acquires the total driving current I, and the total driving current I is judged to determine whether the electromagnetic valve in the hydrogen valve fails or not.

1.4 The number of the hydrogen storage bottle is increased by 1, the step 1.3) is repeatedly executed, and the detection is stopped until a > n. At this time, the opening states of all the bottle valves in the hydrogen system and the serial numbers of the hydrogen storage bottles with opening faults are fed back.
Thus, the open fault detection of all the bottle valves in the hydrogen system can be completed.

2.1 A) the hydrogen supply is turned off.
2.2 Controlling to close all the bottle valves at the end parts of the hydrogen storage bottles, detecting the total driving current I, and judging whether the total driving current I is 0: if the value is 0, indicating that all the bottle valves are normally closed and have no closing fault, feeding back that all the bottle valves in the hydrogen system have no closing fault, and ending the whole closing fault detection method flow; if the valve is not 0, indicating that one or more bottle valves are not normally closed, closing the valve, entering an overhaul mode, and executing the step 2.3).
2.3 Manual shut-off valves in all bottle valves are closed to shut off the hydrogen supply.
2.4 The solenoid valves in all the bottle valves are controlled to be opened, the serial number of the hydrogen storage bottle is set as a, and the initial value is set as 1. And controlling to close the electromagnetic valve in the end bottle valve of the hydrogen storage bottle a.
2.5 Comparing the total driving current I before and after closing the electromagnetic valve, judging whether the total driving current I after opening the electromagnetic valve is smaller than the total driving current I before opening the electromagnetic valve and the reduced amplitude is within [70% I,130% I ]: if yes, recording that the electromagnetic valve corresponding to the hydrogen storage bottle a has no closing fault, and executing the step 2.6); otherwise, recording that the electromagnetic valve corresponding to the hydrogen storage bottle a fails and cannot be normally closed, and executing the step 2.6).
2.6 The number of the hydrogen storage bottle is increased by 1, the step 2.5) is repeatedly executed, and the detection is stopped until a > n. At this time, the closing state of all the bottle valves in the hydrogen system and the hydrogen storage bottle number with the closing failure are fed back.
Thus, the closing failure detection of all the bottle valves in the hydrogen system can be completed.
It should be noted that, in this embodiment, when the opening failure detection is performed on the solenoid valve in the hydrogen system, not only the opening of the solenoid valve but also the opening of the manual shutoff valve is controlled, so that the normal operation of the hydrogen system is not hindered, and even if one or a plurality of solenoid valves have the opening failure, the power supply to the whole vehicle can be completed. In other embodiments, when the open fault detection is performed, only the solenoid valves are controlled to open, and whether the solenoid valves have open faults or not is detected one by one according to the total driving current.
