MotorD&D Motor Systems, Inc. ES-31 Series Wound DC
a bit small, but it works OK. I'm worried about it getting too hot.
Drivetrainstock 4 speed, no clutch
ControllerCurtis 1231C
Batteries20 Exide GC2-H, 6.00 Volt, Lead-Acid, Flooded
Basic golf car batteries supplied through NAPA. They sag a lot (IMO).
System Voltage120 Volts
ChargerQuickcharge 120v/12a
big heavy transformer based semi-smart charger. Seems to be isolated. No user adjustments to voltage or current. Pulls 17-18 amps from the outlet, not good for 15A circuits!
HeaterTwin hair dryers modified always on high heat/high speed ducted into the body heater tubes under the rear seat. 3600 watts of heat ought to warm it up quick!
DC/DC Converter HWZ 120->12V 300W
Isolated 300W converter. So far so good. Seems ok when the output is short circuited (whoops).
InstrumentationLink-10, voltmeter, ammeter (Westach).
The voltmeter seems to stick a little.
Top Speed50 MPH (80 KPH)
still unknown. I've had it up to 50 a couple of times.
Accelerationseems the same as the old ICE
Range30 Miles (48 Kilometers)
expected range. I've had it as far as 20 miles in start-stop traffic on 35 and 40 MPH roads to 60% DOD.
Watt Hours/Mile262 Wh/Mile
From the battery, average speed. 332 Whr/mile form the wall.
EV Miles
Start:66,000 Miles (106,194 Kilometers)
Current:66,042 Miles (106,261 Kilometers)
Total:42 Miles (67 Kilometers)
Seating Capacity2 adults
Curb Weight0
I'm sure it's a little over the GVW of 2844lbs with two adults in it! I need to find a scale.
TiresBig O M+S 165R15 86S
Conversion Time180 hours
Conversion Cost$11,000
Additional FeaturesUpgraded to disk brakes in the front (needed).
Changed rear torsion bars to 28mm (26mm would have been better, and/or add coil-over shocks to help distribute the weight).
Spare tire is still accessible.
Insulated and covered (in the cab) batteries.
I did the conversion for a local Boise resident. She owns it and drives it now. She is very happy with it!
