Electric Vehicle Conversion
by GREMCO OnLine

We converted a 1978 Datsun Kingcab pickup to an electric vehicle. Originally, we had planned to put a prototype of a new controller being developed by SAJE into this conversion. For right now, we are using an Auburn "Kodiak" water-cooled controller. Last year, we upgraded the system to 144 VDC, using 12 Optima Group 31 Yellowtops, Russco charger with boost transformer and Rudman Regulators. Eight of the batteries are under the bed of the truck, which slides back and tips up for access. We also installed an electric heater core in the original ductwork, as well as other minor improvements.   EV Photos

We are now finishing up a 1986 Metro Sprint upgrade. This car was originally converted by the Howe brothers of Brooks, and until Oct., 2006 held the 72-volt street conversion record speed for NEDRA, the National Electric Drag Racing Association. We have upgraded it to 120 volts, redesigned the layout, added an electric heater core, Rudman Regulators, and an 8" ADC motor to replace the original 6.7" which was too small and burned up! We also added an E-Meter and a tach, as well as a 12V gauge for the accessory system, which now runs off an Optima Redtop and a Hughes DC/DC converter. This car will be for sale as soon as we are satisfied with its performance. If you are interested, contact us!

We had a 48-volt go-kart at the 1999 Woodburn EV Show; some of you no doubt have seen it! It features a bright yellow Indy car body (with decals), Optima Yellowtops, Curtis 1209 controller, chain drive (3.3:1 ratio), and an ADC 5" motor. The German film crew that was at Woodburn starts their video with a sequence of this kart taking off down the dragstrip!

Our aim is to do conversions for people in the wintertime, when our regular work is slow. Not too many people wanting to irrigate their fields or lawns in the winter around here!
