A voltage detection apparatus includes first to third circuit boards are provided on first to third battery packs of a battery system respectively. The first circuit board includes a first voltage detection portion detecting a voltage of the first battery pack, a control portion controlling the first voltage detection portion, and a first insulation device which connecting the first voltage detection portion with the control portion. The second circuit board includes a second voltage detection portion detecting a voltage of the second battery pack, and a second insulation device connecting the second voltage detection portion with the control portion. The third circuit board includes a third voltage detection portion connected in series with the second voltage detection portion and detecting a voltage of the third battery pack. The control portion controls the second and third voltage detection portions.
