That Mustang is probably worth more than a new electric car in some parts of the world. Sell it and buy a car that would make a better electric with the money? http://www.trademe.co.nz/motors/used-cars/ford/auction-748754922.htm

It was very light, it was reasonable aerodynamics, and enough room for batteries. John Bryan's Ghia was one example. He carefully measured the efficiency of his Ghia, and got it under 100 watthours/mile. That's good enough for a 100-mile range even on lead-acid batteries. The only cars that do better are things like James Worden's Sunrise, which was built as an EV from the ground up, and got as low as 60 watthours per mile. > But I went ahead and bought the Mustang the day before yesterday. The Mustang is still a pretty good candidate. It's still a small light car, and the aerodynamics aren't too terrible. Plus, it's a classic car that many can appreciate! I believe John Wayland converted one for someone. He's a genius at building beautiful high-performance conversions -- have you contacted him for details? > I'm expecting not much more than a tenth the all-electric miles A low range expectation makes your job a lot easier. I've been reading this thread while on vacation, and you have received a lot of great advice. It must be confusing; but it's better to have too many choices rather than too few, though it may not seem that way at the time. :-) I'm interested as well, as I have a small Chevy pickup and have been thinking about exactly the same sort of conversion. I don't know much about what Netgain was doing in their solution. If you have contact information on it, let me know! Given their other products, I'm sure it was a DC brushed motor. This would be a cheaper approach, and would deliver far more torque for its size than AC. If their motor had interpoles or a sepex field, it could also have done regen as easily as an AC motor. I don't think your hybrid control problems will be nearly as difficult as you think. The Mustang just has a carburetor and simple throttle linkage. Add the EV controller's potbox to the accelerator linkage. Then add some kind of mechanical link that disconnects the throttle linkage from the carburetor when you switch to EV mode (so you're not "pumping" the gas and flooding the engine when it's not running). Then, provide a manual switch to select: - ICE mode: Carburetor linkage connected, EV controller off. - EV mode: Carburetor linkage disconnected, EV controller on. Shift to neutral so you're not forcing the ICE to rotate. - Hybrid: Bot enable at once. In hybrid mode, both the ICE and EV motor will naturally provide an amount of torque controlled by the accelerator pedal. They won't fight each other; their torques will just add. If you're in ICE mode and driving at some particular speed and accelerator pedal position and turn on hybrid mode, the EV motor will add torque, and you will speed up. But your natural response to lift the gas pedal slightly will correct for it. If the EV motor/controller has regen, you will get it just by letting up the gas pedal. You could also shift the transmission to neutral, so as much as possible of your braking is done by the EV motor. It won't matter for your car, but in a vehicle with power steering, power brakes, air conditioning, etc. one could also leave the ICE idling in EV mode (since the throttle linkage is disconnected). This way, the ICE powers all the accessories, using a minimal amount of gasoline, while you EV motor does all the "driving". Thus, you can drive it manually with only a little "finesse". It only gets complicated if you want a system that automatically starts and stops the ICE, and switches between modes based on some criteria. -- The definition of research: Shoot the arrow first, and paint the target around where it lands. -- David Van Baak -- Lee Hart's EV projects are at http://www.sunrise-ev.com/LeesEVs.htm _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
