Abstract: According to embodiments described herein managing power storage and discharge from or charge to a battery array that includes a plurality of individual batteries, is provided by: determining an aggregate demand for power from the battery array; performing one of discharging or charging via a first battery of the plurality of individual batteries from a first state of charge to a second state of charge based on a test profile configured to characterize the first battery, wherein the test profile is unrelated to the aggregate demand; and performing the one of discharging or charging via a second battery of the plurality of individual batteries to compensate for a difference between power discharged or charged by the first battery according to the test profile and the aggregate demand.
