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
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.
Batteries64 Winston LYP90AHA, 3.20 Volt, Lithium-Polymer
Exide Sonnenschein Traction battery made in Germany :-)
Expected to last for 50-60.000km
As of 2013/14: They did those 50.000km.
Almost. But died anyway.

Today, 2014-08-09:
64 Cells 3.2V/90Ah, 32 in series, two strings in parallel get me 102V/180Ah and stripped about 300kg off the car's weight.
System Voltage102 Volts
2.2kW Charger to work on 220V.
100% Charge in 8-10 hours.
Can be accessed by software to be configured to charge any battery type available.

Charger is used to charge the Winstons without any change. It still charges CC/CV and works perfectly.
Solid State Relay added to turn off the charger via EMUS BMS when charging is complete.
HeaterDiesel powered Eberspaecher.
Consumes about 300-400mL/h
8 liter reservoir is filled from the original gas inlet.
DC/DC ConverterSiemens
built into the controller
InstrumentationBattery SOC instead of Gas-meter.
Idiot-Lights for temperature, charging and charging status

EMUS Battery management can show a lot of info on Android device.
Cool, Bond-like gadget :-)
Top Speed63 MPH (101 KPH)
Does 100km/h in standard configuration.

Now - 300kg less in weight - does 100 easily :-)
Acceleration0-50km/h in about 11s.
Not a racing car but most reliable :-)
Range70 Miles (112 Kilometers)
Watt Hours/Mile250 Wh/Mile
Uses about 13-15kWh/100km including thermal battery management to heat the battery compartment.
EV Miles
Current:83,000 Miles (133,547 Kilometers)
Seating Capacity4 adults
Curb Weight2,663 Pounds (1,210 Kilograms)
1510kg empty with lead-gel batteries on board
1210kg empty with Li-Ions
1890kg maximum allowed
Tires4. All black, round and full of air :-))

Larger allowed but doesn't make sense.
Filling up to 3 bar 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$
