Title (EN) VEHICLE BATTERY CURRENT SENSING SYSTEM
(FR) SYSTÈME DE DÉTECTION DE COURANT DE BATTERIE DE VÉHICULE
Abstract:
(EN) A current sensing system, comprising at least one magnetic tunnel junction device placed adjacent to a current carrying conductor electrically connected to a battery of a vehicle. The magnetic tunnel junction device is configured to measure a magnetic field around the conductor. A monitoring device is operatively connected to the magnetic tunnel junction device, wherein the monitoring device is configured to receive the magnetic field measurement and determine an estimate of the current flowing through the conductor.
(FR) L'invention concerne un système de détection de courant comprenant au moins un dispositif de jonction à effet tunnel magnétique placé de manière adjacente à un conducteur de transport de courant connecté électriquement à une batterie d'un véhicule. Le dispositif de jonction à effet tunnel magnétique est conçu pour mesurer un champ magnétique autour du conducteur. Un dispositif de surveillance est connecté de manière fonctionnelle au dispositif de jonction à effet tunnel magnétique, le dispositif de surveillance étant conçu pour recevoir la mesure de champ magnétique et déterminer une estimation du courant circulant à travers le conducteur.
