Vehicle1995 Volkswagen Golf III
1995/96 Volkswagen built less than 150 cars like this in cooperation with Siemens
MotorSiemens 3-Phase AC
22kW liquid cooled 3ph permanent magnet synchronous machine
DrivetrainManual transmission with clutch. Five gears, most of the time only 1-3 in use.
ControllerSiemens Simovert refit
IGBT-Based.
Siemens took the Simovert concept and rebuilt this to suit the needs of a car.

Can be accessed by proper software to configure drive parameters like max. current.
This Controller includes the DC/DC-Converter for the 12V on board supply as well.
Batteries16 Sonnenschein EXIDE 6V/180Ah C5, 6.00 Volt, Lead-Acid, Gel
Traction battery made in Germany :-)
Expected to last for 50-60.000km
System Voltage96 Volts
ChargerSiemens
2.2kW Charger to work on 220V.
100% Charge in 5-6 hours.
Can be accessed by software to be configured to charge any battery type available
HeaterDiesel powered Eberspaecher.
Consumes about 300-400mL/h
8 liter reservoir is filled from the original gas inlet.
DC/DC ConverterSiemens
13.2V/60A
built into the controller
InstrumentationBattery SOC instead of Gas-meter.
Idiot-Lights for temperature, charging and charging status
Top Speed63 MPH (101 KPH)
Does 100km/h in standard configuration.
Acceleration0-50km/h in about 11s.
Not a racing car but most reliable :-)
Range44 Miles (70 Kilometers)
Goes 70km in town during summer.
Can do 85km on country roads with a lot of slipstreaming ;-)
Gets down to about 50@ -10°C
Does not like frozen batteries so keep it connected during cold times
Watt Hours/Mile320 Wh/Mile
Uses about 20kWh/100km including thermal battery management to heat the battery compartment.
EV Miles
Current:37,500 Miles (60,337 Kilometers)
Seating Capacity4 adults
Curb Weight3,324 Pounds (1,510 Kilograms)
1510kg empty
1890kg maximum allowed
Battery weight about 480kg
Tires4. All black, round and full of air :-))

175/70/13
Larger allowed but doesn't make sense.
Filling up to 3bar to decrease energy consumption works great!
Conversion TimeThis car was an EV from the beginning.
No conversion done
Conversion CostNew car in 1995 was 50.000 Deutschmarks, roughly 25500Euro, 34000 US$
Additional FeaturesThermal battery management.
As long as the car is connected to the grid, battery compartments are kept warm. At least about 12°C.

Car cannot be driven as long as the charger is online.
Foolproof :-)
Great car but in 95 too expensive.
Bought this in May '07 completely reworked.
New motor, new inverter, new charger, new batteries
with 33.000km on the meter.

And my company has EV-parking areas with electricity for free :-)

Batteries were new when I bought the car.
Time will tell what happens if replacement becomes necessary.

Nanosafes?
Li-Tecs?
Thundersky?
Europositrons?
Maybe Fortus ??
Or an EEstore ????

Who knows......

Today (January 2010) it looks like Thundersy.
24kWh/120V/140kg gets in the range of slightly above 5k€.
