Abstract
A number of cells can be determined before control for a battery without providing cell number setting and input means. The cell number determination device comprises voltage measuring units that select an “i”th cell among cells that are connected in series and that configure a battery, and that measure a voltage value between a terminal in which the “i”th cell and an (i−1)th cell, which is in one location higher than the “i”th cell, are connected and a ground potential line, voltage comparators that determine an existence, nonexistence or normality of the cells by comparing a voltage value of an (i+1)th cell that is in one location lower than the “i”th cell with the voltage value of the “i”th cell measured by the voltage measuring units and a cell number determination unit that determines a number of assembled cells and normal cells and cell assembled locations in the battery.
