A charging circuit for charging accumulators, in the case of which current measurement is carried out in the line to the accumulator in order to monitor the charging process. In order that it unnecessary to carry out any internal voltage doubling to produce a reference voltage, a small constant current is taken from the output current in order to produce the reference voltage. At the start of the charging process or in order to reproduce a normal, controlled charging after a short-circuit, a circuit element is present which ensures that a small constant current always flows to produce the reference voltage.
