Hyundai Sonata LF 2014-2019 Service Manual / Engine Electrical System / Charging System / Description and Operation
| Description |
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.
