Abstract
A comparator (,) compares the voltage of a battery (,) with a switchable reference voltage (Uref,A, Uref,B,,) and supplies a signal (IS) if the voltage of the battery passes the reference voltage. The switching point of the reference voltage is defined by means of a first resistor (,). By means of the first resistor the number of cells of the battery is set to one or two. A second resistor (,) in series with the battery enables an additional voltage to be obtained in order to correct the reference voltage for the type of battery cell used.
