Abstract: A two-cell battery management system may include a switching network comprising a plurality of switches configured to electrically couple two battery cells to one another and a first load configured to receive electrical energy from the two battery cells and control circuitry configured to dynamically control the switching network among a plurality of switching configurations comprising a first switching configuration in which the first load is in parallel with both of the two battery cells, a second switching configuration in which the first load is in parallel with a first battery cell of the two battery cells and is electrically isolated from a second battery cell of the two battery cells, and a third switching configuration in which the first load is in parallel with the second battery cell and is electrically isolated from the first battery cell.
