This is our prototype, finished in august 2010.
We did 15 more Smarts since then.
Motor N50 3-Phase AC
25kW Motor, 130Nm,
enough for excellent acceleration in 3rd gear!
Drivetrain25kW AC, we can shift at standstill between 2-3-4 gear. I
hardly ever need anything else that the 3rd.
ControllerCurtis 1238-7501
Very reliable AC controller. This model is limited to 120V. Programmable via VCL.
Batteries64 CALB/Skyenergy SE70Ah, 3.40 Volt, Lithium Iron Phosphate
Cells have 76Ah at delivery. All same voltage
System Voltage109 Volts
ChargerElcon PFC 3000
With CAN-Option.
HeaterDBK ceramic heating element
DC/DC ConverterZivan CP3
InstrumentationCurtis 840, Guantuo BMS Monitor, custom user interface
Top Speed70 MPH (112 KPH)
At this speed the range is reduced.
Range86 Miles (138 Kilometers)
140km in summer, 110km in the winter
Watt Hours/MileIn the city with regen the Smart takes under 10kWh.
Country and highway driving is about 12-14kWh/100km.
EV Miles
Start:86,572 Miles (139,294 Kilometers)
Current:134,107 Miles (215,778 Kilometers)
Total:47,535 Miles (76,483 Kilometers)
Seating Capacity2 adults
Curb Weight1,900 Pounds (863 Kilograms)
The last one we built had a pack of panasonic 18650ies and
the weight was about 1800 lbs (820kg).
TiresBrabus rims, aluminum
Conversion Timearound 8 Months. New conversions are done in one month.
Additional FeaturesWe build a new middle console that houses a button interface and the BMS display.
Regen works in 2 phases: step off the accelerator (15%), touch the brake panel (65%).
Regen is off when roads are slippery, especially in winter.
TURN-E converts ICE cars to electric drive in southern germany.
The Smart was our first encounter and we love to drive it every day.

We will do a highend version with 80-100kW motor and enough capacity to do 250 kilometers.

We finished work on a Speedster Replica with 100kW Brusa Drive train and a 48kWh battery pack. We did close to 8.000mls with the Speedster this year. Part of that distance was the WAVE Electric Car Rallye through Germany, Austria an Switzerland.
