Abstract: An apparatus for establishing an operation plan is an apparatus for establishing an operation plan for a battery system to augment old batteries with new batteries and may include at least one processor; and a memory configured to store instructions executed by the at least one processor to determine a number of first batteries initially installed in the battery system based on a preset minimum required amount of discharge energy; and derive operation plan information including a plurality of augmentation time points for second batteries to be sequentially incorporated into the battery system with the first batteries and a number of the second batteries to be incorporated for each of the plurality of augmentation time points, based on the preset minimum required amount of discharge energy and an expected degradation degree of the first batteries.

Abstract: A regulator and an organic light emitting diode display including the regulator are disclosed. The regulator includes a reference voltage generating unit generating a reference voltage from an input voltage, a voltage division resistor circuit dividing a voltage of an output terminal of the regulator to generate a feedback voltage, a comparator comparing the reference voltage with the feedback voltage, a transistor that is turned on or off based on an output of the comparator and switches on or off the input voltage supplied to the output terminal, and a sink current breaking circuit for discharging a sink current flowing in the output terminal to a ground level voltage source.
