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.
DC current appears at
alternator "B" terminal. The charging voltage of this alternator is
regulated by the battery voltage detection system (or ECM - with
AMS).
The main components of
the alternator are the rotor, stator, rectifier, capacitor, brushes,
bearings and V-ribbed belt pulley (or OAD : Overrunning Alternator
Decoupler). The brush holder contains a built-in electronic voltage
regulator.
Alternator
Management System (AMS)
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 lowers the
charging rate when accelerating. Lowering the charging rate will allow
more engine power for accelerating.
The system increases
the charging rate when decelerating. The system uses the unused power of
the decelerating engine and increases the charging
rate. |
