Charge/discharge control method for battery pack and charge/discharge control apparatus for battery pack

Abstract

It is an object of the invention to provide a charge/discharge control apparatus for a battery pack which is capable of performing SOC control and reducing the SOC variation through simple processes, and a control method thereof. In order to achieve the aforementioned object, A charge/discharge control apparatus for a battery pack having a plurality of cells according to one aspect of the invention includes a voltage detection portion that measures a voltage of each set of a predetermined number of cells provided in the battery pack, a computation portion that computes a state quantity of each set of the predetermined number of cells based on the voltage measured by the voltage detection portion, and a charge/discharge control portion that performs a charge/discharge control based on a least state quantity that is a least one of the state quantities of the sets of the predetermined number of cells.
