There is no EM Clutch like in an aircon compressor system. There is just a relay in the charging circuit, on off on off only. With the relay open (circuit broken) the alternator offers no load.ejay20tee;215214 said:Race cars dont need so much electrical power i suppose?
Given the hard stop start WOTs of a race-prepped car, wouldnt this result in premature failure of the circuit?
Just my 2 cents.

Coolest thing from BMW the last decade. Simple tech but nobody thought of it.
Doesn't disconnecting the alternator and eliminating alternator load give you better acceleration? The alternator load is `considerable' no?Shaun;215398 said:I think the concept has been thought of many times and since a long time ago, just that energy efficiency has not been a focus, or cost effective, till now with all the crazy gas prices and them looking to get a whole lot worse.
As for racing, it is a good idea to stay at least remotely relevant to consumers. The cost of developing a highly reliable and efficient system for racing will be justified by trickle down to road cars. In the racing context alone, and with current regulation, it makes little sense because there is no focus on fuel efficiency. It is changing though.. led by LMP and soon F1.
shaun, you heard it here first.Shaun;215422 said:It is something, but I don't know if I would call it considerable. I'd say somewhere under 10hp. There are cheaper more inefficient ways to make 10hp than to develop and package regen. systems. When public focus starts to shift towards efficiency, then regulations will evolve and push the teams to stay relevant, forcing them to go in that direction. F1 is making huge steps.
In order to know the true picture of what's happening, we need digital electronics to do a logging function through some serial port. If we go analog only, we will have to measure from fuel consumption on whether it's working or not.Shaun;215450 said:It certainly seems like a good idea, but I'm not sure the OEMs would have passed up such a great 10 dollar system if it didn't have a weakness. I suspect that with current alternators, the override condition would exist much of the time (not enough time under neg. accel. to maintain charge given average vehicle draw), so you effectively end up at square one. I'm only guessing. Please let us know how it ends up. It would be great if it works.
free 10HP for your EVO!!! For 10 bucks. At least at launch you can take out almost any car.ejay20tee;215489 said:Cool.
Nice thing to have.
