More Information
Summary: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.
