Ok, had a thought coming home tonight and I think it warrants a new thread unless people shoot it down immediately.
I'm definitely eager to follow the advice of people this time around and I'm not doing anything
until I get some valuable input.
So here's how it stands. The delta trike is disassembled into a rolling chassis with differential, the motor and electronics, and the batteries. I have the batteries up for sale on Craigslist and I've sold 1, 5 more to go. I'm looking as well on craigslist for a buyer for the rolling chassis to use for some fun project,
though I'm recommending it not be used for anything that will actually see the roads.
So what's left is to do something with the motor, controller etc. I'd hate to pawn them off and in fact am not willing to do so except as an extreme last resort.
I had considered another bike but am concerned that it will not help me as I won't be able to commute with it. The most I could do is use it for short trips to the store. It would take a long time to pay off under that circumstance.
So here's my new idea.
Put it on my 96 Geo Metro connected direct to the crank using the existing unused Poly-V belt slot (for air conditioning I think). I would gear the max Motor RPM to match the max Engine RPM, I could then team it with some small U1 batteries (free with 50% charge from scrap pile) (I.E. I can kill them with great frequency with no ill effect) (Unless there's potential for a thermal event!)
and it would serve just to smooth out the power demand on the motor for hill climbing etc. Of course the big question here is what effect would the extra drag on the engine during off times have. Would it negate any gains?
I'm far from having all the details worked out but my initial thought is that if I didn't have the motor in regenerative mode on throttle off, (or if i can tune that regeneration to be quite small) The drag would not be that significant. In addition would there not be a way to remove the alternator and just put a step down converter to keep the car battery charged up?
My thought would be to have two throttles for the DC motor, one linked to the gas pedal and made adjustable, and a separate one that i could activate manually. (Thinking of putting my motorcycle twist throttle on the hand brake handle) Now what would happen if i gave the DC motor power without pressing the gas pedal for the engine? Would it not just look to the engine computer like I'm coasting down a hill and put itself in fuel cut until I press the gas?
Would really like input on this point!
I've got so much more to say, but this is a good start for the basic idea. Looking forward to feedback.
By the way, since I've got nearly everything I'd need, I could do a trial run of this outlaying only about $60 for a pulley and a belt. Is it worth a try at that price? Anyone have a link to someone that's done this?
If nothing else it would give me a 20HP boost, (on a 53HP engine i might add)
