NOT perpetual motion, altenator regen?

Alright now bear with me guys, it accured to me that since I'm utilizing the 9" ADC double shaft motor,and I'm not using the double shaft end for any purpose, why not use pullys and belts to drive an altenator ( free wheeling most of the time), coupled with switches so that when I hit the brakes it turns on the altenator, slows down the vehicle and acts as a form of regeneration. I've already been told that my series DC motor isn't suitable or designed for regen and I'm mostly interested in the range of my vehicle. I can imagine that even in the freewheeling state said altenator would decrease my range just by turning the shaft, but what of the regen. possibilities could they significantly increase my range? I do live in a little bit of a hilly regon as a matter of fact if i go one way from my house I immeadiatly asscend a 300-400ft hill, I would love to be able to recapture some of that expended energy on the other side of the hill with regen......... comments?

The braking from this set up can be quite strong. I will look up a link for you. This fellow did exactly what you want. I kept it as I was going to do this. I did mount the clutch...

He's getting about 10 amps at pack voltage. I can barely feel 10 amps of regen in my car, and it won't give you any noticeable range. For all the work he put in he basically ended up with nothing as far as I can tell.

Maybe I'm missing something then, but 10 amps at 160 volts is 1.6KW or about 2 hp, doesn't seem like enough to cause a skid, except maybe on ice with bad tires. For range, unless you have a 10 mile downhill regenning at 10 amps you probably wouldn't get even a mile of range from that setup.

*I suppose the rear brakes plus 10 amps of regen could skid the wheels in the snow.

And actually the video shows 177volts and a peak of 18 amps, so even more power than we calculated at 160V and 10 amps. Makes a bit more sense now, though I still doubt it does much for his range.
