Title
(EN) SYSTEMS AND METHODS FOR DE-ENERGIZING BATTERY PACKS
(FR) SYSTÈMES ET PROCÉDÉS POUR METTRE HORS TENSION DES BLOCS DE BATTERIE
Abstract
(EN) Systems and methods for de-energizing battery packs in vehicles that receive at least a portion of their motive power from electricity generated from a battery are provided. By way of example, one embodiment includes a battery de-energizer that is configured to electrically couple to a port or receptacle, such as the service disconnect receptacle, on the vehicle and discharge the electrical energy stored in the battery pack. Another embodiment includes a battery management unit (BMU) designed to monitor one or more sensors to determine if a crash has occurred. If a crash is determined, the BMU electrically couples a battery de-energizer circuit to the battery pack to discharge the electrical energy stored in the battery pack.
(FR) La présente invention concerne des systèmes et des procédés pour mettre hors tension des blocs de batterie dans des véhicules qui reçoivent au moins une partie de leur énergie motrice à partir d'électricité générée par une batterie. A titre d'exemple, un mode de réalisation comprend un élément de mise hors tension de batterie qui est conçu pour se coupler électriquement à un port ou un réceptacle, tel que le réceptacle de déconnexion de service, sur le véhicule, et décharger l'énergie électrique stockée dans le bloc de batterie. Un autre mode de réalisation comprend une unité de gestion de batterie (« Battery Management Unit » ou BMU) conçue pour surveiller un ou plusieurs capteurs pour déterminer si un accident s'est produit. S'il est déterminé qu'un accident s'est produit, la BMU couple électriquement un circuit de mise hors tension de batterie au bloc de batterie pour décharger l'énergie électrique stockée dans le bloc de batterie.
