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: A system is provided. In some examples, the system includes a control circuit and a plurality of monitor circuits including a first monitor circuit. In a production mode, the control circuit is configured to test the plurality of monitor circuits. In a storage mode after testing the plurality of monitor circuits in the production mode, the control circuit is configured to test the plurality of monitor circuits more than once. In an assembly mode after testing the plurality of monitor circuits in the storage mode, the control circuit is configured to test the plurality of monitor circuits. In one or more examples, the control circuit is configured to skip the storage mode and test the plurality of monitor circuits in the assembly mode after testing in the production mode.

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.
