Abstract:
A voltage measurement device for measuring an output voltage of a battery assembly includes voltage addition sections that add a predetermined voltage value to output voltages of the cells, voltage detection sections that detect addition voltages which are output voltages of the voltage addition sections corresponding to the cells of the individual blocks, A/D converting sections that digitize analog voltage signals of the addition voltages detected by the voltage detection sections, and a control section that outputs voltage measurement request signals to the voltage detection sections respectively, and that acquires the addition voltages, subtracts the predetermined voltage value from the acquired addition voltages and provides voltage values after the subtractions, as the output voltages of the cells.
