Think of it this way.
The alternator is a faucet and the battery is a glass. If the glass is full, the faucet wont fill it any more so it turns off (stops charging the battery). If you drink from the glass, after you drink a certain amount, the faucet will turn back on and fill the glass back up.

^^^ that right there is total awesomeness ! fantastic explanation...
SO... for the dumb at heart, why after my 100km drive did the car say "battery discharge while stopped" and only went after a night on the ctek
oh wait, maybe I have answered my question, the alternator on newer BMW's only charge the battery on overrun, not on good old cruising ?
