Vehicle1972 Volkswagen VW Van
120 volt DC drive EV.
MotorAdvanced DC FB1-4001 Series Wound DC
9 inch diameter motor
Weighs 143 lbs
DrivetrainStandard VW manual transaxle
ControllerCurtis 1231C
Batteries10 Deka AH marine/RV, 12.00 Volt, Lead-Acid, Flooded
ust replaced the old battery pack (August-2010)
System Voltage120 Volts
Lester Charger 110vac/220vac input, 120volts DC output. The 220VAC
setting really pounds the amp-hours into the battery pack, brings up an
almost discharged pack to "full" in three hours or so!
HeaterNone at this time, I have a small "milk shed" portable heater to adapt to
the front cabin of the van. This will take 120 VDC off the drive pack. I
also have a 12 volt plug in "defroster unit" from Harbor Freight that
does take the frost off the inside windshield nicely. As I ride a
motorcycle in the Colorado winters, I'm just happy to be riding in an
enclosed compartment!
DC/DC Converter None at this time
I run the accessory battery as a "dead loss" set up. I have a one-amp
solar PV panel on the van roof to keep it charged. I also "top off" using
a 12 volt charger.
Instrumentation120 volt meter (the "gas guage"), 12 volt meter to monitor accessory
battery, ammeter ("power meter") reading off a shunt in motor drive
Top Speed55 MPH (88 KPH)
Runs very smoothly!
AccelerationGood, but REALLY pulls the amps!
Range40 Miles (64 Kilometers)
That's with a fresh, fully charged set of batteries. After a year of
operation, I'm down to 20 miles of range. (Still adequate for most trips
in town)
EV Miles
Start:165 Miles (265 Kilometers)
Current:890 Miles (1,432 Kilometers)
Total:725 Miles (1,166 Kilometers)
Seating CapacityTwo in front seats. Three more in the rear seat. The five batteries in the
rear compartment are covered with a wooden bench seat. The original
three pairs of seatbelts are still in place.
Curb Weight0
Unknown at this time
TiresNothing special - what came with the van.
Conversion TimeSeptember 2007 to March 2008.
Just about all mechanical/electrical work is done.
Conversion Cost$5,000 for the van
about $6,300 for EV parts
I purchased the van from a woman in the Aspen area in Colorado. I purchased all my EV components
from Bob at EV America, in Wolfsboro, New Hampshire.
I cannot say enough about his friendly, knowledgeable and helpful manner! "Held my hand" when
needed, very supportive of my first full-scale EV conversion project
In 2015, I sold the van to a nice couple in San Antonio. It was time to renew the batteries and I just
could not afford to do it. They came up with a tow rig, took it back and had it driving around in a
couple of days! Sorry to see it go but it has a nice, new home!
I also have a three-wheeled motorcycle EV. See 1094 for that one!
