Hyundai Sonata: 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.
In addition, the charging voltage of this alternator is regulated by the
battery voltage detection system.
The main components of the alternator are the rotor, stator, rectifier,
capacitor brushes, bearings and V-ribbed belt pulley. The brush holder contains
a built-in electronic voltage regulator.

Alternator Management System
Alternator management system controls the charging voltage set point in
order to improve fuel economy, manage alternator load under various operating
conditions, keep the battery charged, and protect the battery from over-charging.
ECM controls generating voltage by duty cycle (charging control, discharging
control, normal control) based on the battery conditions and vehicle operating
conditions.
The system conducts discharging control when accelerating a vehicle. Vehicle
reduces an alternator load and consumes an electric power form a battery.
The system conducts charging control when decelerating a vehicle. Vehicle
increases an alternator load and charges a battery.
