Abstract:
1. A cell control device, comprising: a discharge circuit, comprising first switches that select each of a plurality of unit cells that are connected in series, and that discharges the each unit cell selected by the first switches; a charging circuit, comprising second switches that select each of the plurality of unit cells that are connected in series, and that charges the each unit cell selected by the second switches; a voltage detection unit that detects a voltage of each unit cell via voltage detection lines respectively connected to positive electrodes and to negative electrodes of the plurality of unit cells; an oscillator that irradiates high frequency electromagnetic radiation upon the voltage detection lines; and a discharge control unit that controls opening and closing of the first switches, thereby performing discharge of the each unit cell, and a charging control unit that controls opening and closing of the second switches, thereby performing charging of the each unit cell, based on voltages of the plurality of the unit cells that are detected by the voltage detection unit.
