Abstract: A voltage monitoring device has a capacitor circuit having capacitors connected in series, first switches connecting end terminals of the capacitor circuit to specific electrode terminals of unit cells in a battery pack, second switches connecting remaining electrode terminals of the unit cells to the connection nodes between the capacitors, first voltage detection sections corresponding to each of the capacitors, a second voltage detection section connected to the end terminals of the capacitor circuit, and a microcomputer which selectively performs a first process of charging each capacitor, and a second process of charging the capacitors simultaneously. The respective specific electrode terminals correspond to the unit cells, and are arranged at an interval corresponding to the number of connection nodes formed between the capacitors. The microcomputer performs a polarity switching process of adjusting for the adjacent capacitors to have a same polarity of the charged voltage before performing the second process.

Abstract: A battery monitoring apparatus monitors a state of a nickel hydrogen battery. The apparatus includes a board having a high voltage part having a voltage detection section detecting a voltage of the nickel hydrogen battery, and a low voltage part operating at a voltage lower than a voltage of the high voltage part, a housing that accommodates the board, and an attachment member that is attached to an opposed portion of the housing, which is opposed to a board surface of the board to attach the housing to a predetermined position. A passage is formed between the opposed portion and the attachment member. The passage extends from an opening part provided at a circumference part of the housing and along the opposed portion. The passage is provided at a position that overlaps with the high voltage part, when viewed in a normal direction of the board surface.
