Has anybody any thoughts on "intelligent" alternator control? Modern cars control the exciter current through various feedbacks (EG Mercedes). They charge on the overrun, when slowing down in gear and under various situations, but don't charge the battery back up to full straight away.

The same could be achieved with a voltage switch/relay on the exiter wire to the alterntaor. EG turn on when voltage is below 11.9 volts (emergency) and turn off when above 13.9 volts. You could also wire the brake lights into the exiter wire so that the alternator charges at idle with the foot on the brakes.

Thoughts?
