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.

Dependent claims

A system, comprising:

a battery that includes one or more cells;
wherein the system is configured to:
charge the battery from a first end of discharge voltage to a first voltage;
discharge the battery to a second end of discharge voltage, greater than the first end of discharge voltage;
in response to discharging the battery to the second end of discharge voltage, cease at least one function of the system;
charge the battery from the second end of discharge voltage to a second voltage, greater than the second end of discharge voltage and less than the first voltage;
discharge the battery to a third end of discharge voltage, less than the second end of discharge voltage and greater than the first end of discharge voltage;
in response to discharging the battery to the third end of discharge voltage, cease the at least one function of the system;
charge the battery from the third end of discharge voltage to a third voltage, greater than or equal to the second end of discharge voltage;
and
discharge the battery to the first end of discharge voltage.

8 more elements

A method, comprising:

charging, from a first end of discharge voltage to a first voltage, a battery of a system;
discharging the battery to a second end of discharge voltage, greater than the first end of discharge voltage;
in response to the discharging the battery to the second end of discharge voltage, ceasing at least one function of the system;
charging the battery from the second end of discharge voltage to a second voltage, greater than the second end of discharge voltage and less than the first voltage;
discharging the battery to a third end of discharge voltage, less than the second end of discharge voltage and greater than the first end of discharge voltage;
in response to the discharging the battery to the third end of discharge voltage, performing the ceasing the at least one function of the system;
