Abstract
An uninterruptible power supply adapted to be connected between an AC line and a load, comprising a battery system, an inverter, and a transformer, and a controller. The battery system stores battery power. The inverter is operatively connected to the battery system. The transformer is operatively connected to the AC line, the load, and an inverter winding operatively connected to the inverter. The controller controls the inverter to supply power to the primary winding using battery power stored in the battery system based on a cost value indicative of reduction of life of the battery system.
