|Location||Redmond, Washington US map|
|Vehicle||1972 Volkswagen Karmann Ghia |
Well maintained but un-restored coupe, originally from Canada's west coast.
|Motor||Netgain Warp9 Series Wound DC|
Using the CanEV VW adapter kit.
(De-iced and re-mounted in a day!)
|Drivetrain||Original stock transmission.|
|Controller||Logisystems 144V-156V, 1000amp|
Died after 4yrs and was replaced with 750A I found used.
|Batteries||12 Deka 8G31, 12.00 Volt, Lead-Acid, Gel|
Going with a slightly used set of Deka group 31 gels for the first set of batteries.
There are 6 in the front and 3 on either side of the motor at the back.
|System Voltage||144 Volts|
|Charger||Delta-Q Technologies 2x 72V|
The Delta-Qs are fully featured and well supported. I have the programing dongle so I can mess with them if the need arises.
|Heater||Electric heat (ceramic) and battery blankets.|
Richard at REV has crafted a nice combination of relays that can switch from AC to DC for the heating element. The fan/control will be driven by AC, via a small 12V inverter. A programmable lighting timer is used to pre-heat the cabin while the car is on charge.
|DC/DC Converter||Go Power GPC-45|
45A, more than enough for the old VW wiring!
|Instrumentation||Westach 120-180VDC analog|
Westach 1000A analog
Both a motor and battery 1000A shunt, DPDT microswitch for the ammeter.

Equus Tachometer (noisy signal)
|Top Speed||87 MPH (139 KPH)|
67 mph at 96V.
87 mph at 144V.
|Acceleration||Marginally better than stock @144V, but the Gels don't put out more than 600A.|
|Range||21 Miles (33 Kilometers)|
33 miles was the top range attempted when the batteries were newer.
Down to 21 miles now that they have a few cycles / thousand miles on them.
|Watt Hours/Mile||233 Wh/Mile |
It draws just under 100A at 140V at 60mph: ~233Wh/m in cold weather.
One day, all lubricants will be upgraded to synthetics.
|Seating Capacity||2 + 2|
|Conversion Time||Less than one year.|
