  • Distributed feedback control systems and logic for battery management system (BMS) operation
    Patent number: 11777152
    Abstract: Presented are feedback control systems for monitoring battery system hardware, methods for making/operating such systems, and vehicles with wireless battery management systems (WBMS) governed through distributed feedback control. A method of operating a WBMS includes a wireless-enabled manager device selecting a batch of cell module assemblies (CMA) within the WBMS to communicate with to thereby retrieve data for their respective battery modules. A manager access control list (ACL) is created with respective media access control (MAC) addresses and ID data for the selected CMAs. A wireless connection is established between the manager device and a respective cell monitoring unit (CMU) for each selected CMA based on the corresponding MAC addresses and ID data in the manager ACL. The manager device downloads, from the CMU of each selected CMA, device data for each battery modules associated with the selected CMA. The manager device then switches the operating mode for each CMU.
