Patent attributes
A battery monitor apparatus includes unit batteries connected in series; a battery pack including battery modules connected in series by conductive members, each battery module including two or more of the unit batteries; voltage detection ICs to detect voltages of the unit batteries and the conductive members in circuit intervals connected in series, by potential differences of the circuit intervals; and an electronic control unit to monitor states of the unit batteries. At least one voltage detection IC detects a voltage of at least one of the two unit batteries adjacent to a conductive member, and detects a voltage of the conductive member adjacent to the two unit batteries. The electronic control unit monitors the states, based on the voltages of the unit batteries, and one or more of the voltages of the conductive members detected by one of the voltage detection ICs.
