Problems solved by technology

In the existing technology, a hot-melt valve has been equipped in the design of the hydrogen cylinder, which automatically exhausts when the temperature reaches a certain temperature point. This is a passive exhaust, and the timing of the exhaust is not necessarily the best, and safety cannot be guaranteed.

Abstract

The invention discloses a hydrogen fuel cell car hydrogen safety device. A hydrogen fuel cell car comprises a VCU (5) and a hydrogen cylinder (1); an exhaust pipeline (3) is arranged on a hydrogen safety device and connected to the hydrogen cylinder (1); an electromagnetic valve (2) is arranged on the exhaust pipeline (3); and the electromagnetic valve (2) is connected with the VCU (5) through a signal wire. The invention further discloses an active hydrogen safety releasing method of the hydrogen fuel cell car hydrogen safety device. By using the technical scheme, hydrogen is actively exhausted when a danger is confirmed and the hydrogen needs to be exhausted by using a flame sensor, a temperature, a collision sensor and other safety detection sensors, and therefore, the hydrogen exhaustopportunity is optimal; the hydrogen use safety coefficient is increased, and the safety of personnel in a car and the integral loss minimization are guaranteed to a maximum limit.

Description

technical field [0001] The invention belongs to the technical field of hydrogen fuel cell vehicle safety. More specifically, the present invention relates to a hydrogen safety device for a hydrogen fuel cell vehicle. In addition, the present invention also relates to an active hydrogen safety release method of the hydrogen safety device of the hydrogen fuel cell vehicle under dangerous conditions. Background technique [0002] Hydrogen fuel cell vehicles are the ultimate vehicle to replace petroleum because hydrogen is used as fuel, and they are green and environmentally friendly. At the same time, hydrogen is an extremely dangerous gas. It is easy to burn when mixed with air, and the energy storage battery has frequent accidents. The circuit on the car is complicated, and fire accidents are inevitable. Therefore, the fuel cell must be equipped with emergency measures. On the contrary, the accident may magnify. [0003] Utilizing the escape characteristics of hydrogen, u...
