Distributed feedback control systems and logic for battery management system (BMS) operation

A method of operating a wireless battery management system (WBMS), the WBMS including a plurality of cell module assemblies (CMA) each having a respective battery module and a respective cell monitoring unit (CMU), the method comprising:

• selecting, via a wireless-enabled manager device, a batch of the CMAs to communicate with to thereby retrieve data for their respective battery modules;
• generating a manager access control list (ACL) with respective media access control (MAC) addresses and identification (ID) data for the selected batch of the CMAs;
• transmitting the generated manager ACL from the manger device to a remote computing device;
• comparing, via the remote computing device, the manager ACL with a master ACL to determine if the MAC addresses in the manager ACL correspond with an associated list of MAC addresses in the master ACL;
• selecting a new batch of the CMAs in response to the MAC addresses in the manager ACL not corresponding with the associated list of MAC addresses in the master ACL;
• establishing a wireless connection between the manager device and the respective CMUs of the selected CMAs in the new batch of the CMAs based on the respective MAC addresses and ID data of the new batch of the CMAs;
• downloading, via the manager device from the respective CMUs of the selected CMAs in the new batch of the CMAs, device data for each of the battery modules associated with the selected CMAs in the new batch of the CMAs;
• and
• switching an operating mode for each of the respective CMUs in the new batch of the CMAs.

• establishing a wireless connection between the manager device and the respective CMUs for the selected CMAs based on the MAC addresses and the ID data in the manager ACL, wherein establishing the wireless connection includes:
• wirelessly transmitting, via the manager device, an electronic ping to the respective CMU of each of the CMAs in the selected batch of the CMAs;
• determining if the wireless connection is successfully established with each of the CMUs;
• and
• transmitting a new electronic ping to each of the CMUs in which it is determined that the wireless connection was not successfully established with the CMU;
• downloading, via the manager device from the respective CMUs of the selected CMAs, device data for each of the battery modules associated with the selected CMAs;
• and
• switching an operating mode for each of the respective CMUs.
