A battery voltage equalization device for an automotive battery formed from a plurality of batteries connected in series includes: a voltage measurement unit that measures respective battery voltages of the batteries; a current measurement unit that measures a charge-discharge current of the automotive battery; a cell balancing unit that equalizes the respective battery voltages of the batteries; and a control unit that performs a voltage equalization control through the cell balancing unit on the basis of the battery voltages measured by the voltage measurement unit. The control unit starts the voltage equalization control on the condition that the voltage equalization control is determined to be necessary on the basis of the respective battery voltages and that a discharge current of the automotive battery measured by the current measurement unit is determined to be stable.
