NGBSDG BSD interface to alternator: Function

For the alternator with BSD interface, the following functions are implemented in the engine-management control unit:

• Alternator activation and deactivation based on parameters defined in the application
• Definition of the maximum approved load factor for the alternator
• Control of the alternator's response to demand spikes (Load Response)
• Calculates alternator torque based on the proportion of total capacity being used
• Diagnosis of the data wire between the alternator and the engine-management control unit
• Stores alternator faults in the fault memory
• Activates the charge indicator lamp in the instrument cluster via CAN

Use of an alternator equipped with a BSD interface does not change the charge indicator lamp's display concept relative to that employed with earlier alternators.

The system ensures that the alternator continues to discharge its primary function even if communications between the alternator and the engine-management control unit are interrupted.
