Abstract:
A voltage detection apparatus includes: a battery including a plurality of unit cells mutually connected in series; a plurality of blocks, each block including at least one of the plurality of unit cells; a plurality of voltage detectors, each detector connected to respective one of the blocks, and detecting a voltage between both ends of the unit cell in the one of the blocks; a plurality of reference power sources, each source connected to respective one of the voltage detectors, and at least one of the reference power sources having higher accuracy than the other reference power sources; and a correcting unit which corrects a detection result of the voltage detector which is connected to the other reference power source on the basis of a detection result of the voltage detector which is connected to the reference power source with the higher accuracy.
