Voltage, Current, AmpHours, State-of-Charge, Temperature
Top Speed70 MPH (112 KPH)
On a flat road surface. Hills cause a significant decrease in performance depending on incline.
Acceleration0-100km/h in 20sec.
Using only 3rd Gear. Gear-shifting without a clutch takes a bit more practice, but 2nd to 3rd gear starts should get about 3-5 seconds decrease with practice.
Range25 Miles (40 Kilometers)
Worst case due to the very hilly road conditions in Vogtland. Low charge at 50% shut-down to keep battery from running too low.
Watt Hours/Mile225 Wh/Mile
24.6Ah after a total of 35km.
Average speed 60kmh on my local hilly test track in Heinsdorfergrund.
EV Miles
Start:35,543 Miles (57,188 Kilometers)
Current:35,935 Miles (57,819 Kilometers)
Total:392 Miles (630 Kilometers)
Seating CapacityCurrent weight is 740Kg, orginal Trabant was able to have a max capacity of 1000kg so with conversion there is 260Kg.
Seating capacity is 4.

If needed I could send BOM and information to get parts.
Additional FeaturesCustomized rear spring for additional battery weight.
New steering column assembly - lucky find in my spare parts collection.
Re-built transmission.
This car was originally ordered in the DDR and delivered on Oct 15. 1987 by my now mother-in-law, and since the first registration always garaged. During the DDR there was very long leadtime for ordering. We have been keeping it with care, and wanting to convert it now since I first road it in the summer of 1990.

The current configuration and performace results are in conjuction with Kelly controller KDH12600. The current performance with this controller are similar to the original 2-Stroke (26HP) ICE. This motor is well known to be very loud and very stinky, hence my desire to convert.

German TÜV inspection has been passed without difficulty in Oct 2009. Still trying to find the time to change the controllers from Kelly to Zapi controller with regenerative braking. This should have significant effect on top speed, acceleration and range of vehicle.
