Description
Technical Field
The invention relates to the technical field of detection and authentication, in particular to a device for testing the performance of a hydrogen storage system of an electric automobile.
Background
A Fuel Cell Vehicle (FCV) is a vehicle powered by electric power generated by an on-board fuel cell device. The fuel used in the in-vehicle fuel cell device is high-purity hydrogen or high-hydrogen reformed gas obtained by reforming a hydrogen-containing fuel. The power aspect differs from that of a normal electric vehicle in that the electric power for FCV is from a vehicle-mounted fuel cell device and the electric power for electric vehicle is from a battery charged by a power grid. In order for a fuel cell vehicle to continue traveling, it is necessary to continuously supply hydrogen to the fuel cell, just as a normal vehicle needs to supply gasoline or diesel. Therefore, it is necessary to install a hydrogen storage system on a fuel cell vehicle, the so-called hydrogen storage system including a plurality of hydrogen storage tanks and an intake line connected to the inlet of the hydrogen storage tanks and a hydrogen delivery line in which the hydrogen storage tanks are connected to the fuel cell.
Since hydrogen is a flammable and explosive gas, no leakage or explosion can occur throughout the hydrogen storage system. Standard GB/T26990-2011 specifies that when a standard passenger car is to be evaluated for hydrogen permeation and leakage, it is required to be limited in a closed space, pressurized to 100% of the nominal working pressure, to ensure that the permeation and leakage of hydrogen does not exceed 0.15NL/min under steady-state conditions, and also specifies that the hydrogen storage vessel, pressure regulator, main shut-off valve, pressure relief device, seal, piping, etc. should be qualified products meeting the relevant standards.
Currently, no means for detecting the above criteria has emerged in the market.

Because the components in the air inlet pipeline, the hydrogen storage tank and the hydrogen transmission pipeline are more, if the hydrogen gas source is simply connected with the inlet of the air inlet pipeline, the pressure drop is larger along with the gas transmission, namely the pressure born by the hydrogen storage tank and the hydrogen transmission pipeline is not the standard specified pressure, so that the whole hydrogen storage system is divided into three sections for improving the accuracy, and the three sections are connected with the hydrogen gas source respectively except the original connection pipeline, thereby reducing the influence of the pressure drop on the test result as much as possible.
The closed box is internally provided with a bracket for fixing the air inlet pipeline, the hydrogen storage tank and the hydrogen delivery pipeline.
And a hydrogen detector for measuring the concentration of hydrogen in the closed box is arranged in the closed box. In order to detect the leakage degree of the whole hydrogen storage system, the whole hydrogen storage system is fixed in a closed box, and along with the flow of hydrogen gas from a hydrogen gas source to the tail gas treatment unit, the leaked hydrogen is concentrated in the closed box and detected by a hydrogen detector, so that whether the leakage amount of the hydrogen meets the regulation is judged.
The device is provided with a controller for controlling the opening and closing of the flow valve, and the controller is connected with a pressure detector between the air inlet pipeline and the hydrogen storage tank and a pressure detector between the hydrogen storage tank and the hydrogen delivery pipeline. The compensation of the hydrogen pressure of each section can be automatically completed through the controller and the pressure detector.
