Embodiment

[0031] The invention relates to an electric purging control device for a fuel cell bus, which is used to eliminate the safety and quality problems caused by "purging" hydrogen and water in pipelines before the fuel cell system is shut down. Such as figure 1 As shown, the device of the present invention includes a fuel cell system controller 2 , an emergency power-off switch 3 , a fuel cell system work request switch 4 , a signal processing module 5 , a display screen 6 and an alarm 7 . The signal processing module 5 is a signal recognition processing circuit, which has an enabling terminal, an input terminal and an output terminal. The fuel cell system controller 2 has an enabling terminal, an input terminal and an output terminal. The fuel cell system controller 2 is connected to the cleaning module of the fuel cell system. The fuel cell system work request switch 4 is a switch arranged beside the driving operation panel 9 . The emergency power-off switch 3 is a disposable...

Abstract

The invention relates to an electric purging control device for a fuel cell bus. The electric purging control device is connected to a fuel cell system, and the fuel cell system comprises a fuel cellsystem controller, a sweeping module connected with the fuel cell system controller and a whole vehicle ON-gear power supply follow-up control loop. The electric purging control device is characterized in that it comprises an emergency power-off switch, a fuel cell system work request switch and a signal processing module; the fuel cell system work request switch is connected with the input end ofthe fuel cell system controller; the output end of the fuel cell system controller is connected with the input end of the signal processing module; the emergency power-off switch is connected with the input end of the signal processing module; and the output end of the signal processing module is connected with the whole vehicle ON-gear power supply follow-up control loop in parallel. Compared with the prior art, the method has the advantages of improving the safety, reducing the failure rate of the whole vehicle and the like.

Description

technical field [0001] The invention relates to the technical field of fuel cell system equipment, in particular to an electric purge control device for a fuel cell bus. Background technique [0002] Fuel cell buses have become a hot spot for new energy buses. By using clean and renewable energy, they can realize the advantages of fast energy loading, high driving range, no pollution, and low cost. However, the current development of fuel cells is still in its infancy, and the current fuel cell system must be "purged" after shutdown, that is, power-off purge, mainly to clean the water and hydrogen in the pipeline after power-off , is a necessary process after the shutdown of the fuel cell, but at present, this operation is basically controlled by humans, and the effectiveness and safety cannot be guaranteed. This process needs to be constrained, otherwise, during the power-off process, the shutdown may occur due to the negligence of the driver and the complete "purge" stage...
