Abstract: An equalization device for equalizing voltages of battery cells connected in series includes equalization switches, resistors, and a control circuit. Each equalization switch has energization terminals interposed between terminals of a corresponding battery cell. A current path between the energization terminals conducts when a control voltage not less than a threshold voltage is applied between control terminals of the equalization switch. Each resistor is connected between the control terminals of the corresponding equalization switch. The control circuit switches an equalization execution state and an equalization stop state in accordance with an equalization signal provided for each battery cell. In the execution state, the control circuit passes an electric current through the corresponding resistor to generate the control voltage not less than the threshold voltage. In the stop state, the control circuit causes the corresponding resistor to generate the control voltage less than the threshold voltage.
