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.
