Abstract
A device for monitoring battery cells of a battery string under load condition. The device has differential voltage units for each battery cell, wherein a band-pass filter is arranged downstream of each differential voltage unit, wherein the band-pass filters are connected to rectifier circuits with a smoothing circuit arranged downstream, and wherein the device is designed so the output signals of the smoothing circuits are supplied to an evaluation unit and are compared for deviations in relation to a standardized output signal.
