A voltage equalizer 1 includes voltage detectors 2 and 3 that detect voltages V81-V84 and voltages V91-V94 of cells 81-84 and 91-94, switches 41-44 and 51-54, and a controller 7 that repeatedly sets a lowest voltage among voltages detected by the voltage detector 2 or 3 to be a target voltage Vt1 or Vt2 in each of the battery packs 8 and 9, and that repeatedly turns on/off each of the switches 41-44 and 51-54 such that the voltages of the cells other than the cell having the lowest voltage become the target voltage Vt1 or Vt2 in each of the battery packs 8 and 9, until the controller 7 determines on the basis of the voltages V81-V84 and the voltages V91-V94 detected by the voltage detectors 2 and 3 that a cell balance control operation does not need to be performed.
