Abstract: A battery monitoring apparatus includes wire sections each connected to a node of corresponding adjacent two of the unit cells of a battery pack at one end thereof, and branched into a first branch section and a second branch section at another end thereof. Each of the first and second branch sections is constituted of a positive part connected to a positive electrode of the corresponding unit cell and a negative part connected to a negative electrode of the corresponding unit cell. The battery monitoring apparatus includes an equalizing switch provided between each of the first wire pairs, and a voltage detector to detect a voltage between each first wire pair, and an equalizing section which performs an equalizing process to equalize a terminal voltage of each unit cell by turning on the corresponding equalizing switch depending on a result of voltage detection by the voltage detector.
