One more shot at this, then I'm going to bed. In most every car, the alternator spins happily away producing power all the time and keeping the battery topped off. What BMW is doing now is only engaging the alternator when the propulsion power required of the engine is low. Is this somehow newfound energy? No. Every car produces power under these conditions. The efficient part is that an alternator load is not added to the propulsive load. So, the alternator is only making power part of the time, requiring a larger battery that can carry the car theough the periods when power isn't being generated and stand more frequent off/on charging. Is this efficient? YES. Is this regeneration? Absolutely NOT.
I understand now your battery fixation. I don't understand BMW's stretching the facts.
This "not understanding regeneration" is some concoction of your mind.
You seem to be fixated on this aspect. I have never led on that I believe it to be anything other than what BMW has stated. I have discussed this in other threads in the past as well.
I have told you I understand BMW's implementation. There is nothing else I can do if you, for some reason, fail to acknowledge that.
