Abstract
In a voltage detection apparatus for a battery pack, a pair of electric paths are respectively connected to a pair of ends of a unit battery defined as one of battery cells configuring a respective cell group or one of serial connections of the battery cells. A voltage detecting unit detects voltage across terminals of the unit battery via the electric paths. An electrically conductive member connects: a positive terminal of one of two adjacent cell groups and a negative terminal of the other of the two adjacent cell groups. A bypass connects one of the electric paths connected to one of both ends of the conductive member; and the other of the pair connected to the other of the both ends. A bypassing unit disposed in the bypass allows current to flow in the bypass when voltage across both terminals of the conductive member has exceeded a specified voltage.
