Abstract

The invention relates to the technical field of hydrogen energy vehicles, in particular to a high-pressure safety system for a fuel cell hydrogen energy automobile. The high-voltage safety system comprises a front cabin high-voltage distribution box, a rear cabin high-voltage distribution box, a fuel cell stack, a fuel cell air compressor controller, a fuel cell PTC, a warm air PTC, an air conditioner compressor, an electric control hydraulic power-assisted steering gear, a power battery, a driving motor controller, a bidirectional DC / DC, a super capacitor, a driving motor and a fuel cell aircompressor. The super capacitor, the bidirectional DC / DC, the drive motor controller, the power battery, the forecabin high-voltage distribution box, the electric control hydraulic power-assisted steering gear, the warm air PTC, the air conditioner compressor, the fuel cell PTC, the fuel cell air compressor controller and the fuel cell stack are sequentially connected in series through loop interlocking wiring harnesses. Therefore, a high-voltage interlocking loop is formed.
