Kia Cee'd: Charging System / Description and operation
The charging system included a battery, an alternator with a built-in regulator,
and the charging indicator light and wire.
The Alternator has eight 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 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.
