try BMW

BMW has been using a system for years that shuts off the alternator.
they claim a few % extra MPG.
The computer shuts off the alternator if battery charge is ~ 80%.
The other 20% kicks in the alternator when braking thus providing charge and some small regenerative / retarding effect.
The system has a name, but it escapes me now.
