Abstract
Individual voltages of la plurality of batteries or voltage sources which are connected in series and voltages on both ends of the plurality of batteries or voltage sources are detected. An offset value of a differential amplifier is determined through an arithmetic operation for the detected voltages. The offset value thus determined is used to correct the measured values of the battery voltages.
