ABSTRACT:
An overvoltage detecting apparatus for a combination battery can easily detect whether an overvoltage detecting function is normal or not. In the overvoltage detecting apparatus, with respect to blocks of cells constituting the combination battery, reference voltage generators, voltage dividers, comparators, and switching circuits for performing an ON/OFF operation between the cells and the reference voltage generators are arranged, and an output from the comparator of an upper cell controls the switching circuit of the next lower cell, so that a detection result is sequentially transmitted to lower cell blocks. A control signal given from a battery controller to the uppermost cell block is changed, and the normality/abnormality of the overvoltage detecting function is determined by checking whether a detection signal follows the control signal.
