Abstract
The battery pack management apparatus for managing a battery pack having a series connection of battery cells is provided with a management unit for each of unit batteries each of which includes a single battery cell or a plurality of adjacent battery cells included in said battery pack. The battery pack management apparatus includes a selection circuit selecting one of the unit batteries, and a voltage detection circuit detecting a voltage across the selected unit battery. The management unit provided for the selected unit battery is configured to perform a management process (discharge process, for example) other than detection of the voltage across the selected unit battery on the selected unit battery.
