Abstract
A voltage detection device includes voltage detection sections that measure cell voltages in the blocks, a control section, and (N−1) or less converters that raise the voltage, which is supplied from a DC power source, to a voltage of a driving power source for the voltage detection section. In a case where a voltage detected by at least one voltage detection section among the voltage detection sections which operate by the power supplied from the respective converters, exceeds a predetermined threshold value, the control section controls at least one voltage detection section among the voltage detection sections to operate using the cell voltage of each of the blocks as a driving power source and acquires the cell voltage in each of the blocks.
