Charging System Description - Overview

The alternator outputs the power corresponding to the electrical power consumption, varies to multi stage and acquires the reduction of the fuel consumption by proper output control. The 12 volt battery sensor attached on the 12 volt battery negative terminal measures the current value, voltage value, 12 volt battery temperature and internal resistance, changes to the signal and sends to the PCM. The PCM calculates the proper AC output based on the received data and sends commission data of the proper generating to the alternator for the required generating.

*Depending on the vehicle condition, the variable control is not activated.
