I've been considering a different approach for an electric conversion project.

Now that the lighter weight large scale Li-Ion Batteries are starting
to become available, a different type of electric vechicle becomes
practical. So, I would request your thoughts on the idea of taking a
lightweight 4wd such as a Rav-4 or CR-v, disconnecting the rear
differential from the FWD tranny, and attaching a motor. Run the
vehicle on Li-ion electricity until it poops out then use gas.

It would seem that even with a range of 20-30 miles, this would make a
great conversion plug-in hybrid. So we would desire have a
high-voltage, low AH battery system.

Do you think that the additional electric motor weight and Li-ion
would work in a small SUV?

Do AC or DC electric motors have a significant amount of drag or
rotational friction when un-powered?

I've read of only one other conversions that connect directly to the
differential, an on-going BMW 7-series conversion. Any have
experience with this type of coupling?

I was considering the first phase of conversion to run the motor at
idle to power the power steering/brakes & 12V, and strap a motor
directly to the rear differential.

Thanks for your consideration.
Mark.

Mark,
I am working on a diesel hybrid plug in using a VW pickup and retaining the
front wheel diesel drive, and adding electric drive to the rear axle. It
can be pure electric, parallel hybrid, or diesel. This is a very small, and
light pickup and in diesel, gets nearly 50mpg.
