Abstract: A battery management system (BMS) is presented herein. The BMS has a master node. The master node includes a master transceiver and a controller communicably coupled to the master transceiver. The BMS has a plurality (n) of slave nodes. Each slave node of the n slave nodes includes a slave transceiver for communicably coupling to at least one battery monitor. The controller of the BMS is configured to direct the master transceiver to establish a communications network with the n slave nodes. To establish the communications network, the controller is also configured to respectively assign each of the n slave nodes to non-overlapping time slots of a superframe. The controller is further configured to direct the master transceiver to consecutively receive uplink (UL) transmissions from the n slave nodes in the non-overlapping time slots of the superframe.

Abstract: In an example, a wireless battery management system includes one or more sets of battery cells. The wireless battery management system includes a primary node configured to broadcast a downlink packet in a first superframe. The wireless battery management system also includes a first secondary node coupled to a first set of battery cells. The first secondary node is configured to receive the downlink packet and transmit a first uplink packet to the primary node during the first superframe. The wireless battery management system includes a second secondary node coupled to a second set of battery cells. The second secondary node is configured to receive the first uplink packet from the first secondary node in the first superframe. The second secondary node is also configured to transmit a second uplink packet to the primary node during a second superframe.

Abstract: A method for channel switching by a secondary node. The method includes: receiving, from a primary node, a downlink transmission, measuring one or more statistics about the downlink transmission, determining, from the downlink transmission, an uplink interval, transmitting, to the primary node during the uplink interval, the measured one or more statistics about the downlink transmission, receiving, from the primary node, an indication of a set of useable channels, determining, based on the set of useable channels and at least one of the primary node or the secondary node, a next channel from the set of useable channels, and switching to the next channel based on a switch indication from the primary node.
