Title:
電池制御装置およびこれを備えた蓄電装置
Document Type and Number:
Japanese Patent JP5594893
Kind Code:
B2
Abstract:
A cell control device according to the present invention includes: a discharge circuit that discharges each unit cell selected by the first switches among a plurality of unit cells connected in series; a charging circuit that charges each unit cell selected by the second switches among the unit cells connected in series, and; a voltage detection unit that detects a voltage of each unit cell via voltage detection lines respectively connected to positive and negative electrodes of the unit cells; an oscillator that irradiates high frequency electromagnetic radiation upon the voltage detection lines; and a charging control unit that controls switching of the first switches, thereby performing discharge of the each unit cell, and a charging control unit that controls switching of the second switches, thereby performing charging of the unit cells, based on voltages of the unit cells that are detected by the voltage detection unit.
