Hyundai Venue: 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.
On-vehicle Inpection
•
First of all, check for DTCs...

NOTICE
To prevent damage to the rear window defroster conducting elements bonded
to the inside surface of the rear window, never use sharp instruments or window
cleaners containing abrasives to clean the window.
If you want to defrost and defog the front windshield, refer to the “Windshield
Defrosting and Defogging” section in this chapter...
Inspection
1.
Turn the ignition switch OFF.
2.
Disconnect the mode control actuator connector.
3.
Verify that the mode control actuator operates to the defrost mode when
connecting 12V to terminal 3 and grounding terminal 4...
