Bottle valve fault diagnosis method, equipment, vehicle and storage medium

Abstract

The present invention provides a bottleneck valve fault diagnosis method, equipment, vehicle and storage medium. The method includes: obtaining the hydrogen consumption of two adjacent hundred kilometers of a hydrogenation vehicle, the hydrogenation vehicle includes a hydrogen storage system, and the storage The hydrogen system includes a plurality of hydrogen storage bottles, and each hydrogen storage bottle includes a bottle mouth valve; then, according to the hydrogen consumption of two adjacent 100 kilometers, determine the number of failed bottle mouth valves in the hydrogen storage bottles. Therefore, the above method can not only judge whether there is a failure of the bottleneck valve in the hydrogen storage system, but also can determine the quantity information of the failure bottleneck valve in the hydrogen storage system.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis, in particular to a bottle mouth valve fault diagnosis method, equipment, vehicle and storage medium. Background technique [0002] Hydrogen refueling vehicles have been vigorously promoted due to their advantages such as zero pollution emissions and long driving range. The on-board hydrogen storage system is a key component of hydrogen refueling vehicles, and its hydrogen storage capacity determines the endurance of fuel cell vehicles. Therefore, it is particularly important to make full use of the hydrogen in the on-board hydrogen storage bottle. However, in actual operation, the on-board hydrogen storage bottle may not be able to output normally due to the failure of the bottle mouth valve, thus affecting the cruising range of the hydrogen fuel vehicle. [0003] At present, the fault diagnosis of the bottleneck valve (such as a solenoid valve) of the vehicle-mounted hydrogen storage bo...

However, in actual operation, the on-board hydrogen storage bottle may not be able to output normally due to the failure of the bottle mouth valve, thus affecting the cruising range of hydrogen fuel vehicles

[0003] At present, the fault diagnosis of the bottleneck valve (such as a solenoid valve) of the vehicle-mounted hydrogen storage bottle in the prior art is mainly realized through the pressure fluctuation of hydrogen detected by the hydrogen pressure sensor in the hydrogen storage system. Specifically, if the hydrogen pressure When the pressure fluctuation value of hydrogen detected by the sensor is greater than the preset value, it is considered that the pressure fluctuation may be caused by the failure of the bottle mouth valve

[0004] However, the bottleneck valve fault diagnosis method in the prior art can only judge that there is a fault in the bottleneck valve in the hydrogen storage system, and cannot obtain more information about the fault
