Charging System: Description and Operation

Description

The charging system includes a battery, an alternator with a built-in regulator, and the charging indicator light and wire.
The Alternator has built-in diodes, each rectifying AC current to DC current.
Therefore, DC current appears at alternator "B" terminal.
The regulator is regulates the charging voltage to maintain ECM signal.
The main components of the alternator are the rotor, stator, rectifier, capacitor brushes, bearings, regulator and V-ribbed belt pulley.









Variable charging system is controlled by the ECM.
The ECM receive from the battery sensor about information of voltage, current, temperature, and it helps the battery charge, discharge capability and fuel efficiency by charging voltage control.
The system control with three steps, charge-discharge-normal condition.
