Abstract
A voltage-detecting device applied to a battery pack includes a serially connected body of plural battery cells. Serially connected bodies of at least two of the battery cells of the battery pack form detection blocks; each of the respective battery cells of a detection block, or a serially connected body of a number of battery cells in a detection block that is less than the number of the battery cells of the detection block is taken to be a battery for which voltage is to be detected. Monitoring units includes a main voltage-detecting unit for detecting terminal voltage of each of the batteries; a positive-electrode-side input unit electrically connected to the positive-electrode side of a detection block; a negative-electrode-side input unit electrically connected to the negative-electrode side thereof; and sub voltage-detecting units for detecting terminal voltage of the detection blocks as the state of the battery pack.
