What is the job of the alternator in the vehicle?

The alternator is responsible for charging the car battery and thus for supplying the vehicle with electricity. In the early days of automobile construction, electricity in the vehicle was only required for the light, which is why the name alternator came about. Today, apart from the headlights, it supplies all kinds of electrical devices in the vehicle with electricity. These include, for example, the air conditioning, the electric windows, the speakers or the starter. Other names for the alternator are generator, alternator or dynamo.

The armature (also called rotor) of the alternator is rotated by the V-belt and motor, which creates a magnetic field in the alternator, which in turn generates electricity. The regulator, which is now installed in the alternator in all common models, then regulates this current to the correct voltage, usually 12-14 volts.
