Abstract
When in long term storage, battery degradation is avoided by performing battery charge cycles at a voltage level where a change in the battery's voltage divided by a change in the battery's storage capacity is at a minimum, rather than discharging the battery to its minimum storage capacity and then charging to its maximum storage capacity. Further, based on physical and practical limitations, such battery charge cycles can instead be performed within a range or delta Depth of Discharge (“DOD”) and corresponding battery voltage levels rather than at a single voltage level, while still avoiding battery degradation.
