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...
Other information:
Release Residual Pressure
in Fuel Line
•
There may be some residual pressure even after "Release Residual
Pressure in Fuel Line" work, so cover the hose connection with
a shop towel to prevent residual fuel from spilling out before
disconnecting any fuel connection...
Inspection
Wrap tin foil around the end of the voltmeter test lead to prevent damaging
the heater line. Apply finger pressure on the tin foil, moving the tin
foil along the grid line to check for open circuits...
