Smart Uninterruptible Power Supply And Method

A power supply employs a dynamic charging system and method for charging a battery, as well as a load shedding system and method for conserving battery life in the event of a power failure. The dynamic charging system and method includes at least one step during which the battery is analyzed in real time to determine the actual voltage of the battery, and then determines a charging voltage based at least in part on the actual battery voltage plus a charge differential. The load shedding system and method determines that a power failure has occurred and that the power supply is operating power of a battery, determines that a first event has occurred, and in response thereto terminates battery power to a first subset of components and determines that a second event has occurred, and in response thereto, terminates battery power to a second subset of components.
