ABSTRACT:
In a method for controlling the strength of a charging current when charging a battery by means of an alternating voltage source, the rectified voltage of the alternating voltage source is fed to the battery via a phase control circuit with variable triggering angle. The battery voltage is measured and the value of the triggering angle to be set is identified as a function of the measured battery voltage and the voltage of the alternating voltage source.
