1. A battery pack comprising:
- at least one battery cell;
first and second switches connected to each of the at least one battery cell;
a switch controller for controlling the first and second switches, wherein the first and second switches perform either charging of the at least one battery cell or supplying power from the at least one battery cell;
a voltage measuring unit for measuring a voltage of the at least one battery cell via the first and second switches; and
a controller programmed to select the at least one battery cell according to a residual voltage of each battery cell and a control signal of a terminal, and controlling the switch controller.

Abstract
A battery pack for reducing a memory effect is disclosed. The battery pack includes at least one or more battery cells. A battery cell with the smallest residual voltage is selected from battery cells each having a residual voltage greater than a minimum threshold voltage, and first charged. Power is supplied to a terminal from a battery cell having the smallest residual voltage among battery cells having the residual voltage greater than the minimum threshold voltage, thereby lengthening a life span of the battery pack.
