Abstract: In a management device that manages a power storage module, a voltage measuring unit measures n pieces of voltages across respective n power storage blocks. A ranking unit assigns ranks to the voltages measured across the n power storage blocks in descending order from high to low or in ascending order from low to high. A frequency distribution data generator compiles ranks assigned to voltages measured across the respective n power storage blocks during a set period and generates data about frequency distribution of the ranks for the measured voltages. An abnormality determiner detects an abnormality when information about the ranks differs from information about ranks for the power storage blocks in a normal state.
