Vehicle1995 Volvo 850
MotorAdvanced DC FB-4001a Series Wound DC
19 HP continuous, 85 HP peak. This motor has a shaft on
both ends: one drives the transmission the other drives the
accessory assembly.
ControllerAuburn Scientific PWC600-144 Kodiak
Water cooled
Batteries12 Deka 8A31DT, 12.00 Volt, Lead-Acid, AGM
Each battery is rated at 105aH so the pack is rated at 15
kWh. However, with the Peukert effect, I am getting about
60% of that, or about 10 kWh.
System Voltage144 Volts
ChargerZivan NG3
I used to have 12 individual Soneil 3 amp chargers, one for
each battery. The advantage of this arrangement is that
each battery is charged exactly how much it needs. The
disadvantage is that it only adds about 1 mile per hour of
charging, so it can take over a day to fully charge. Another
disadvantage is that two of the chargers burnt out and
those batteries were damaged before it was discovered.
DC/DC ConverterIota DLS-55
This is actually a 120VAC to 12VDC converter, but it works
fine with the 144VDC battery pack as the source.
Top Speed70 MPH (112 KPH)
Probably will go faster, but this is the fastest I have gone so
Range25 Miles (40 Kilometers)
This was done with 5 miles of freeway driving and the rest
around town with a maximum speed of 40 MPH.
Watt Hours/Mile400 Wh/Mile
Battery to wheel, gets about 2.5 miles per kWh. However the
Soneil chargers are not very efficient so plug to wheel it gets
only 1.6 miles per kWh (625 Wh per mile).
Seating Capacity5 Adults
Curb Weight4,300 Pounds (1,954 Kilograms)
This is the same car as Ben Sharpe had, and has just had the batteries and charger
replaced. (I added the DC-DC converter.)

The car was originally converted by Ken Bancroft in Houston, TX from a brand new 850.
