  • VOLTAGE DIFFERENCE CORRECTION DEVICE AND VOLTAGE DIFFERENCE CORRECTION METHOD
    Publication number: 20160352110
    Abstract: A voltage difference correction device including: a determination which selects at least one of a first correction unit and a second correction unit based on a magnitude of a voltage difference outputted by a voltage difference detection unit that detects a voltage difference among a plurality of cells in a power storage system at a predetermined time interval; and a control unit that drives the first correction unit or the second correction unit selected by the determination unit and controls such that the voltage difference is reduced.
