I'm new to this list having followed a link from the electric auto association on Steve's tractor #12, so little introduction and some G stuff:

I've been into organic food and living ideas for a long time, before the legal definition, involved with NOFA when I lived up north. Along the way went to many workshops with presenters I now know as permaculture authors. I'm also into alternative energy and electric vehicles, on-road and electric tractors. I started out with a converted S-10 pickup truck and a GE Elec-Trak. After getting into the Elec-Traks, the parts supplier of 30 years in Wisconsin retired from that business and... it ended up with me, so I have a warehouse full of parts and blueprints etc. which I'm slowly listing on-line. Since moving to VA got lucky with some state rebates so have 12KW of solar on the shop roof and 2 KW on the house.

It is nice to find a place with others who share all the same intersecting interests. In response to the Electric G comments, I've worked on a G conversion, starting out with the Niekamp kit after visiting Ron on his farm (before he sold off that tractor). I ended up with a different design, but still have that kit sitting around unused. I'd love to find someone who wants it - I can get some of my money back and the new owner gets it way faster than 4 months turnaround since siting here ready to go. Also have a matching motor and controller if desired.

Old thread but like to add that I am a bit of an EV nut. 72 or 96 volts is not enough for a truck. First on-road EV I had was a converted S-10 truck. Started out at 120 volts, I eventually crammed in more batteries, tried 176 volts, then ran 132 volts with a bigger controller (1000 amp till I blew and I went to 600amp). And I loved that truck - great for running around town, including building half a house - hauling wood, mulch, gravel, scafolding, etc. The bigger controller made a huge difference to getting the low end torque needed to get it moving.

Then "upgraded" to one of the few factory built S-10 electrics (same drive train as the EV1 as in Who Killed The Electric Car). Nice truck when it worked, but way too finicky with all the computer systems always throwing error codes. Then came a used Solectria Force. Currently needs rebuilding, so missing my on-road EV fix.

Using a van will reduce your range. It all about the ratio of battery weight to total weight. If doing basic lead acid batteries, aim for at least 1/3 of the weight in batteries, better if can manage 50%. To get an idea of how a particular configuration will perform, there is an on-line EV calculator:

It is getting old at this point so doesn't list any of the newer controllers etc. This one

appears to be a somewhat newer tool, but I haven't used it.

Grant, That is a very nice, clean conversion!
