FCEV (Fuel Cell Electric Vehicle) hydrogen fuel installation unit electric-control initiative hydrogen discharging system

Abstract

The invention relates to the technical field of fuel cell cars, and aims at providing a safe and explosion-proof hydrogen fuel installation unit electric-control initiative hydrogen discharging system. According to a technical scheme, the FCEV (Fuel Cell Electric Vehicle) hydrogen fuel installation unit electric-control initiative hydrogen discharging system comprises an electric control unit ECU,an explosion-proof hydrogen storage apparatus, a fuel cell and a hydrogen discharging apparatus, the hydrogen discharging apparatus comprises a buffer tank, a nitrogen tank, a water trough and an exhausting pipe, a branch pipe which is arranged on a hydrogen supply pipeline between the explosion-proof hydrogen storage apparatus and the fuel cell is connected with one end of the buffer tank, the branch pipe is provided with a second electromagnetic valve, and the other end of the buffer tank is separately connected with the water trough and the hydrogen supply pipeline by virtue of the hydrogen discharging pipeline and a reflux pipeline. One end of the nitrogen tank is connected to the hydrogen discharging pipeline by virtue of a pipeline, a pipeline adopted by the hydrogen supply pipelineand the hydrogen discharging pipeline is a pipeline with an expansion structure and comprises a straight pipe section and an expansion section formed by expanding the pipeline, and the expansion section and the straight pipe section are interconnected to form a whole body. The safe and explosion-proof hydrogen fuel installation unit electric-control initiative hydrogen discharging system is convenient in operation, safe and explosion-proof.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an electronically controlled active hydrogen exhaust system of an FCEV hydrogen fuel installation unit. Background technique [0002] FCEV, short for Fuel Cell Electric Vehicle. The hydrogen used as fuel is chemically reacted with the oxygen in the atmosphere in the fuel cell installed in the car, thereby generating electric energy to start the electric motor, and then drive the car. [0003] But it is precisely because hydrogen is used as fuel that it has to face the ensuing problems, such as the high-pressure hydrogen storage tank used to store hydrogen is heated or in high temperature weather, or the hydrogen storage tank is damaged due to impact. When the pressure in the tank suddenly rises or even leaks, there are safety risks such as combustion and explosion. However, the hydrogen in the hydrogen storage tank is high in pressure and concentration, and it is not easy to...

[0003] But it is precisely because hydrogen is used as fuel that it has to face the ensuing problems, such as the high-pressure hydrogen storage tank used to store hydrogen is heated or in high temperature weather, or the hydrogen storage tank is damaged due to impact. When the pressure in the tank suddenly rises or even leaks, there are safety risks such as combustion and explosion. However, the hydrogen in the hydrogen storage tank is high in pressure and concentration, and it is not easy to discharge directly to the atmosphere. The reason is that if a large amount of hydrogen encounters an open flame in the atmosphere Prone to explosion, not conducive to driving safety
