Abstract

L'invention concerne un appareil d'alimentation électrique destiné à prévenir les incendies sur les véhicules. Selon l'invention, un véhicule classique comprenant un dispositif d'alimentation principale est également équipé d'un dispositif de prévention des incendies et d'un dispositif d'alimentation auxiliaire. Le présent appareil d'alimentation électrique détecte la tension d'alimentation principale du véhicule ainsi que les collisions survenant lors du fonctionnement et détermine si la tension d'alimentation principale à l'instant de la collision ou d'un accident dû à un court-circuit est inférieure à une tension prédéterminée. Si la tension d'alimentation principale s'avère inférieure, le présent appareil intercepte la tension d'alimentation principale afin de prévenir un incendie causé par le court-circuit. Si la tension d'alimentation principale est interceptée, le présent appareil fournit un dispositif d'alimentation auxiliaire aux dispositifs nécessaires à une conduite sûre, par exemple, les freins, la direction assistée et les feux de détresse.
