It has approx 22000 total miles, mostly pure EV.

The car is driveable right now, but the battery pack is tired.  Some
of the batteries have reduced capacity (maybe a third of the pack).
Many of the rest of the batteries seem to be in good shape, although
I can't vouch for their remaining life expectancy.  Optimas do better
with individual monitoring and preferably individual charging.  I had
a long-term project running to build individual battery chargers but
never found the time to finish them (it's too close to what I do at

A possible idea for the buyer would be to use the charging system
that Richard Rau has designed on a Porsche EV.  See the EV Album
entry at http://www.evalbum.com/1638.  Basically, a PFC charger for
bulk charging and individual Soneil chargers for the finish charge.

Another option might be to buy the charging system from Belktronix
(charger, DC/DC and battery monitors) and use this in place of the
PFC-20.  The Belktronix web page is http://www.belktronix.com/
It might be interesting to use the complete Belktronix system (with
controller, charger, battery monitors, etc.

If you were to buy the listed equipment new, the price would come

tires, nor the significant amount of installation work.

I'm asking $10,000 for everything.

I'm also open to offers to remove some of the "EV stuff" and sell
the glider.  One approach would be for me to remove the controller,
charger, DC/DC, batteries and misc support hardware.  This would
leave the motor and it's adapter plate and the battery boxes in the

I'm fairly motivated to sell the car so I can use my garage for other

I'll bring the Prizm to the OEVA meeting tomorrow.
