Battery life extending power supply system

A power supply system includes a battery and a power management system. The power management system is coupled to the battery and to an external power source that is operable to charge the battery using a first charge level. The power management system is operable to determine that a battery power l...

Zusammenfassung:	A power supply system includes a battery and a power management system. The power management system is coupled to the battery and to an external power source that is operable to charge the battery using a first charge level. The power management system is operable to determine that a battery power level of the battery is greater than a first predetermined level that depends on a battery storage option and, in response, disable power from being supplied from the external power source such that power is supplied from the battery until the battery power level is below the first predetermined level. The power management system is also operable to determine that the battery power level of the battery is less than the first predetermined level and, in response, charge the battery with a second charge level that is less than the first charge level until the battery power level is above a second predetermined level that depends on the battery storage option.
