Abstract

In one or more embodiments, one or more systems, methods, and/or processes may: charge a battery from a first end of discharge (EOD) voltage to a first voltage; discharge the battery to a second EOD voltage; in response to discharging the battery to the second EOD voltage, withhold power from one or more cells of the battery to at least one component of a system; charge, from the second EOD voltage to a second voltage, greater than the second voltage and less than the first voltage; discharge the battery to a third EOD voltage; in response to discharging the battery to the third EOD voltage, withhold power from the one or more cells to the at least one component; charge, from the third EOD voltage to a third voltage, greater than or equal to the second EOD voltage; and discharge the battery to the first EOD voltage.
