Abstract

A battery controller 40 for controlling an assembled battery configured by connecting battery groups each including battery cells, includes: voltage measuring units that are provided respectively for the battery groups each to measure a voltage of each of the battery cells included in a corresponding battery group; a minimum value detecting unit that detects a minimum value of the battery cells for each of the battery groups based upon the measured voltage of each of the battery cells; a reference value setting unit that sets a reference value used to determine an abnormal voltage drop for each of the battery groups based upon the measured voltage of each of the battery cells; and an abnormality determining unit that makes a determination that an abnormal voltage drop is present, if a difference between the reference value and the minimum value exceeds a predetermined value, for each of the battery groups.
