Abstract
The apparatus for charging a battery particularly for a motor vehicle, with a self-exciting generator is provided in which the generator pre-excitation is improved during starting in that an additional relay is triggered via the starter arrangement, which relay connects the battery with the exciting winding via an additional line when starting and improves the pre-excitation. The additional relay contains a delay circuit, so that the pre-excitation is improved via the additional line also some time after the starting process. The additional line or current branch can contain the relay switch of the additional relay, a resistor and a diode connected electrically in series and the battery is connected with the exciting winding of the generator by it when the additional relay is energized. A capacitor can be connected in parallel with the additional relay coil to provide an appropriate time delay.
