Description

The charging system consists of the battery, an alternator with an integrated regulator, the charge warning light and wiring. The alternator has eight built-in diodes, each of which converts alternating current to direct current. Therefore, direct current appears at the alternator "B" terminal. In addition, the charging voltage of this alternator is regulated by the battery voltage sensing system. The alternator is regulated by detecting battery voltage. The main components of the alternator are the rotor, stator, rectifier, capacitor, brushes, bearings and the poly-V belt pulley. The brush holder contains a built-in electronic voltage regulator.

Generator Control System

The Generator Control System controls the charging voltage setpoint to improve fuel economy, manage alternator load under various operating conditions, keep the battery charged and protect the battery from overcharging. The ECM controls the generating voltage by duty cycle (charge control, discharge control, normal control) depending on the battery condition and vehicle operating conditions. The system performs discharge control when the vehicle accelerates. The vehicle reduces alternator load and consumes battery power. The system performs charge control when the vehicle decelerates. The vehicle increases alternator load and charges the battery.
