ABSTRACT:
A battery pack system is composed of a plurality of battery pack blocks, each of which is constituted by connecting a plurality of cells in series, that are connected with one another by a combination of serial connection and parallel connection. The battery pack blocks are each provided with a current sensor for detecting current values. Detection results are inputted to a control section, which processes the detected current values using an algorithm constructed in accordance with the connection status of the battery pack blocks. Thereby, an abnormality of the battery pack block is detected, and an abnormal battery pack block is identified.
