Abstract
Determination of a remaining life fraction for a network of batteries during use in an electrical circuit is disclosed. A state of health of the battery network can be determined by measuring a change in impedance characteristics of the individual battery units and/or the battery network as a whole. More specifically, a mode and a severity of a failure can be determined for individual battery units.
