Motor and transmission
Owner's Other EV1991 Chevrolet S-10
LocationSaskatoon, Saskatchewan Canada map
Vehicle1990 Chevrolet Sprint
Motor Unknown Separately Excited DC
Tentatively 21 HP, 120VDC
ControllerOpen ReVolt 500A
Purchased with a Kelly controller, which failed due to a power resistor (no pre-charge = capacitor goes BANG). Open ReVolt from another project
Batteries10 Mismatched, 12.00 Volt, Lead-Acid, Flooded
2 old floor sweeper batteries, 2 used deep cycle marine batteries, 2 yellow-tops, 1 red-top, 1 AGM, 2 fork truck batteries
System Voltage120 Volts
ChargerRussco SC 18-120
An adjustable output voltage charger with constant current and float modes
HeaterNone so far
DC/DC Converter None
None so far. I have a VICOR power supply that may work
InstrumentationSpeedometer. Perhaps an Arduino to show amp-hours, tach
Top Speed25 MPH (40 KPH)
In first gear, with a 500 amp controller, I may be able to get to 25 mph by the time I get to the end of my driveway
AccelerationExpected to be
- good in first gear with a low top-end
- OK in second gear
- golf cart in third gear
Range5 Miles ( 8 Kilometers)
The car has frame rust and is not likely to pass an inspection for road worthiness. 5 miles is up and down my driveway 25 times.
Watt Hours/MileNot good. The gearing will be low. For the weight of the car it should be 300. I would expect 500 - 700 based on poor battery performance
EV Miles
Start:335,106 Miles (539,185 Kilometers)
Current:335,106 Miles (539,185 Kilometers)
Total:0 Miles (0 Kilometers)
    As of 2/10/2013
Seating Capacity4 initially, 1 for testing, perhaps 1 when I'm done.
Curb Weight0
Guess at 3000. Will check once I get enough parts into the car for it to run.
Tiresdonut spares. They roll, and they were C-H-E-A-P!
Conversion TimeWas already done by someone else - motor to transmission was done, some cables routed. Not sure of his time. Mine is about 8 months very part time
Conversion Cost$650 for the car, $250 total for the surplus/used batteries, $250 in parts for the battery cables, $350 for the Kelly controller (half price purchase after the first one failed - my fault), $300 for misc parts (contactors, fuses, relays, etc)
Additional FeaturesUsed to test the individual parts (high voltage junction box, low voltage junction box, field current monitoring, emergency disconnects) for the WIKISPEED electric motor module project

Will likely donate most of it's useful parts to a WIKISPEED build after testing is complete
Someone else's project - I'm finishing it off. Using it for a test bed. Trying things.

One of those 'things' should be a 5 HP 230V surplus AC induction motor on a plywood adapter plate. Driven by a surplus AC drive, plugged into a 200 foot extension cord ... because I want to try it. It should move in 1st gear ...

Recently acquired a surplus 9 inch netgain series wound DC motor. I will try to mount it on the adapter plate that the old aircraft generator is using now, just to see what the difference in performance is

I have GREAT plans ... not so good with the follow through ...
