When hydrogen charging is realized, the solid-state hydrogen storage device 1 is cooled by cold hydrogen, the specific heat capacity of cold hydrogen is large, the heat exchange efficiency is high, the hydrogen charging speed is fast, and the system structure is simple, convenient to use and beneficial to commercial use.

[0040] Further, the solid-state hydrogen storage device management system further comprises a hydrogen discharge pipeline 6, a third flow meter 61, a fuel cell system 7 and a hydrogen utilization controller 8. The hydrogen outlet of the solid-state hydrogen storage device 1 is connected to the fuel cell system 7 through the hydrogen discharge pipeline 6. The waste heat of the fuel cell system 7 in operation provides heat for the solid-state hydrogen storage device 1. Specifically, in the present embodiment, the fuel cell system 7 is a water-cooled fuel cell system, and the fuel cell system 7 provides hot water through its heat exchanger 71 to heat the solid-state hydrogen storage device 1.

[0041] The third flow meter 61 is arranged on the hydrogen release pipeline 6, and is used for detecting the hydrogen flow of the hydrogen release pipeline 6.

If the working conditions of the fuel cell system 7 are met, a signal is sent to the main controller 14 to control the first switch valve 32 to open for hydrogen release. Hydrogen enters the fuel cell system 7 through the hydrogen release pipeline 6, the fuel cell system 7 works to output electric energy, at the same time, the waste heat in the working of the fuel cell system 7 supplies heat to the solid-state hydrogen storage device 1, the solid-state hydrogen storage device 1 absorbs heat to continuously release hydrogen, the third flow meter 61, the pressure sensor 11 and the temperature sensor 12 perform real-time detection and transmit the detection data to the main controller 14, and then the main controller 14 sends the detection data to the hydrogen using controller 8 through the wireless communication module 13. The hydrogen using controller 8 judges whether the solid-state hydrogen storage device 1 does not meet the minimum hydrogen release balance state (for example, the temperature does not decrease, but the pressure and flow continuously decrease, which indicates that the minimum hydrogen release balance state is not met) according to the received flow, pressure and temperature. If so, hydrogen addition is prompted, and a signal is sent to the main controller 14 to close the first switch valve 32. The main controller 14 can accurately know the remaining hydrogen release capacity of the solid-state hydrogen storage device 1 through the hydrogen addition amount and the hydrogen release amount through an algorithm, so as to accurately and timely prompt whether to add hydrogen.
