1. A battery voltage adjusting device comprising:

  • a voltage detecting means, which is provided corresponding to a block including at least one unit cell of an on-vehicle high voltage battery consisting of a plurality of the unit cells connected in series and detects a terminal voltage of the unit cell in the block;

    a charge-discharge means, which charges or discharges the unit cell in the block on the basis of the terminal voltage of the unit cell detected by the voltage detecting means;

    a temperature detecting means, which detects a temperature of the unit cell; and

    a changing means, which changes a time period, from a time point when the charge-discharge means finishes to charge or discharge the unit cell to a time point when the voltage detecting means detects the terminal voltage of the unit cell, on the basis of the temperature of the unit cell detected by the temperature detecting means.
