Title (EN) OPTICALLY COMMUNICATIVE BATTERY MANAGEMENT SYSTEM
(FR) SYSTÈME DE GESTION DE BATTERIE À COMMUNICATION OPTIQUE
Abstract:
(EN) An optically communicative battery management system includes a pack controller and one or more module controllers optically coupled to the pack controller. The module controllers may themselves be optically coupled together in series, and communication from an upstream module controller may be relayed through one or more downstream controllers en route to the pack controller. The pack controller may also send an optical signal that is used by the pack controller to determine whether any one or more of the battery modules is experiencing a safety fault, and the communication channel used to transmit that optical signal may, absent any safety faults, be used to multiplex message data to the module controllers.
(FR) Un système de gestion de batterie à communication optique comprend un contrôleur de bloc et un ou plusieurs contrôleurs de module couplés optiquement au contrôleur de bloc. Les contrôleurs de module peuvent être eux-mêmes couplés entre eux optiquement en série, et une communication à partir d'un contrôleur de module en amont peut être relayée par l'intermédiaire d'un ou de plusieurs contrôleurs en aval vers le contrôleur de bloc. Le contrôleur de bloc peut également envoyer un signal optique qui est utilisé par le contrôleur de bloc afin de déterminer si un ou plusieurs modules parmi les modules de batterie subissent un défaut de sécurité, et le canal de communication utilisé pour transmettre ce signal optique peut, en cas d'absence de défaut de sécurité, être utilisé pour multiplexer des données de message vers les contrôleurs de module.
