Abstract
For each battery sub-module in a plurality of battery sub-modules, a voltage associated with a cell in that battery sub-module is received wherein each battery sub-module in the plurality of battery sub-modules includes a plurality of cells. A battery sub-module is selected based at least in part on the received voltages and a set of one or more loads, which draws power from the selected battery sub-module and is not powered by any other battery sub-module in the plurality of battery sub-modules, is configured so that the set of loads at least temporarily does not draw power from the selected battery sub-module.
