Charging System - Functional Description: Alternator: Notes

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.

The alternator exchanges data with the engine control unit using a serial data interface. The alternator provides the engine control unit with information, e.g. type and manufacturer. This enables alternator-specific information to be processed inside the engine control unit and adapts the control of the alternator to the installed alternator type.

NOTE: Observe intelligent generator control!

With intelligent generator control, the alternator voltage is correspondingly more frequently in the low voltage range in order to achieve a better battery charge.
