Redeployment of energy storage units

Abstract:

Methods for redeploying used battery units can include capturing performance data of an energy storage unit containing a battery unit at the end of its useful life for a primary application, and determining, based on the performance data, a remaining energy output capacity. If the battery unit meets or exceeds threshold performance criteria, the battery unit can be incorporated into a second energy storage unit and reconfigured to reflect the remaining energy output capacity. The second storage unit can include the redeployed battery unit alone, or in combination with any suitable number of additional battery units.
