Abstract
A battery network includes a plurality of heterogeneous batteries coupled to at least one energy source and one energy load, a plurality of switches coupled to the heterogeneous batteries, and the switches controllable having a duty cycle between 0 and 1. A controller is configured to characterize each of the plurality of heterogeneous batteries characteristics, determine duty cycles for each of the plurality of switches based on the characterization such that a charge applied from the at least one energy source or a discharge to the at least one energy load converges to a balanced state for the plurality of heterogeneous batteries, and apply the determined duty cycles to the plurality of switches.
