For those interested, here is BMW's Energy Management Strategy for the E70, dating back a few years.

http://www.bmwmotorsports.org/pdf/e7...Management.pdf

Executive Summary: Penguin's Explorer, referenced above, had a voltage regulator that read battery voltage, and decided whether to charge the battery or not. Worked pretty darn well. OTOH, the above document takes 35 pages to explain when the alternator should be charging the E70, or not.
