Don Price passed away in 2007. He was an avid EV enthusiast and NBEAA member. He drove a 1980 Plymouth Horizon that had been converted to electric approximately when it was new. He knew he was going to die, and donated the car to the NBEAA because he got so much help from the club. The club wouldn't take it for insurance reasons, so Chris Jones the chapter president took it and sponsored its refurbishment, done by SRJC alternative fuel lab classes as a learning experience in exchange for free labor and as the prototype to be documented for a modern economy EV conversion as part of the NBEAA Open Source Electric Vehicle Project.
The original equipment was dead or damaged and very old low performance -- flooded lead acid batteries, SCR controller and off-board ferroresonant traction and accessory battery charger -- so only the EV motor was retained and rebuilt. The new equipment includes low cost lithium iron phosphate cells, a 96V DC MOSFET drive system, and on-board MOSFET traction and accessory battery chargers.
Once completed -- documented, heavily tested, improved, shown to other organizations and the community, hopefully by the end of 2009 -- it will then be auctioned off with a starting price of the investment made by Chris, estimated to be approximately $9K. This prototype will be offered first to students who worked on it at this price, and if only one student bids it will go without auction.
The goal is to make a blueprint for a common kit except for mount adapters specific to model run that in volume would cost less than $5,000 before tax, take less than one weekend to install once ICE parts were removed, and reliably propel any subcompact front wheel drive car greater than 30 miles on average for at least 5 years at top speeds greater than 55 MPH with battery replacement and charging costs similar to or less than gasoline price given the same number of miles driven, with a full shop manual such that any shop could troubleshoot it to the component level quickly and can easily obtain parts overnight.
