Title
(EN) QUICK BATTERY DISCONNECT SYSTEM FOR HIGH CURRENT CIRCUITS
(FR) SYSTÈME DE DÉCONNEXION RAPIDE DE BATTERIE POUR CIRCUITS À COURANT ÉLEVÉ
Abstract
(EN)
A circuit protection system is provided herein that minimizes the disconnection time of a circuit while protecting other electrical components. Some configurations comprise a set of parallel circuit interruption devices, each connected in series with respective fuses. A control device sets a state of the circuit interruption device based on a current of the circuit. Under certain current loads, the circuit is interrupted without causing a fuse to blow. Under other current loads, the circuit is interrupted by having one or more fuses blow.
(FR)
L'invention concerne un système de protection de circuit qui minimise le temps de déconnexion d'un circuit tout en protégeant d'autres composants électriques. Certaines configurations comprennent un ensemble de dispositifs d'interruption de circuit parallèles, chacun connecté en série avec des fusibles respectifs. Un dispositif de commande règle un état du dispositif d'interruption de circuit sur la base d'un courant du circuit. Sous certaines charges de courant, le circuit est interrompu sans provoquer le saut d'un fusible. Sous d'autres charges de courant, le circuit est interrompu par le fait qu'un ou plusieurs fusibles sautent.
