Vehicle-mounted hydrogen storage system device and control method thereof

Abstract

The invention provides a vehicle-mounted hydrogen storage system device and a control method thereof. The vehicle-mounted hydrogen storage system device comprises a hydrogen storage module and a purging module, wherein the purging module is used for blowing out hydrogen leaked in the hydrogen storage module; the vehicle-mounted hydrogen storage system device further comprises a detection module and a control module, the detection module is electrically connected with the hydrogen storage module and used for detecting the concentration of hydrogen in the hydrogen storage module, and the controlmodule is electrically connected with the detection module and the purging module and used for receiving feedback signals of the detection module and controlling the gas purging amount of the purgingmodule. The control method comprises the steps: acquiring the hydrogen concentration in the hydrogen storage module through detection of the detection module, and enabling the control module to control the gas purging amount of the purging module, so that the hydrogen concentration in the hydrogen storage module meets the requirement. By arranging the detection module, the control module and thepurging module, leaked hydrogen in the hydrogen storage module is treated and discharged through detection, regulation and control, and the danger of explosion caused by hydrogen accumulation is avoided.

Description

technical field [0001] The invention belongs to the technical field of fuel cells and relates to a vehicle-mounted hydrogen storage system, in particular to a vehicle-mounted hydrogen storage system device and a control method thereof. Background technique [0002] A fuel cell is a device that uses hydrogen, etc. as a fuel to generate electricity through a chemical reaction with oxygen, and the by-product is only water. It has the advantages of zero emissions, high efficiency, fast start-up speed, and low-temperature operation. Therefore, fuel cells have a wide range of applications, and can be used as power sources in automobiles, aerospace and unmanned aerial vehicles. [0003] Fuel cell vehicles are essentially zero-emission vehicles, which reduce greenhouse gas emissions and dependence on petroleum resources compared with traditional vehicles, and are superior to other battery-powered electric vehicles. Fuel cell vehicles have the characteristics of stable operation and...

But it still has the problem of not dealing with the leaked hydrogen

[0008] Although the existing on-board hydrogen storage system devices are equipped with hydrogen concentration detection devices, the leaked hydrogen has not been effectively treated. Therefore, how to ensure that the on-board hydrogen storage system device can monitor the leaked hydrogen in real time and at the same time be able to detect the leaked hydrogen. Hydrogen is processed to avoid dangers such as explosion caused by hydrogen accumulation
