Vehicle1989 Volkswagen Polo 86C
Originally 760kg, 1675lbs, 1.3l, 40kw (55hv),
MotorKostov K9 144 volt Series Wound DC
Drivetrain4-speed clutchless
ControllerEvnetics Soliton Jr.
Batteries49 Thunder Sky 90ah, 3.20 Volt, Lithium Iron Phosphate
System Voltage157 Volts
TcCharger (Elcon) charger
Heater230V AC heating element in the original heater
core. It has only ~800 watts of power with
this voltage, but it is enough to defrost the
DC/DC ConverterElcon 400w
Also TcCharger, same as Elcon
InstrumentationEv Display
Top Speed105 MPH (168 KPH)
I have driven 80mph or 130kmh (with 200
battery amp limit). Calculated top
speed is 105mph/170kmh. Calculated by YAEC
(Yet another EV calculator).
AccelerationIt accelerates pretty fast with only 200
battery amps. After I add water cooling to
Soliton I'm going to tweak it and add
50-80 bamps and maybe go to 500 motor amps.
It is clutchless so it's kinda hard
to do fast shifting..
Range60 Miles (96 Kilometers)
Calculated range is 60 miles, 100km. I have
actually driven a bit less than 50 miles,
80km in a one charge.
Watt Hours/Mile350 Wh/Mile
TBD slower speed consumptions.. When
travelling at top speed 130kmh
the voltage is around 140V IIRC and
Soliton draws 200 amps from battery.

Highest consumption is:

140v x 200a / 130km/h = 215whrs per km

Or 350whrs per mile.
EV Miles
Start:134,557 Miles (216,502 Kilometers)
Current:134,744 Miles (216,803 Kilometers)
Total:187 Miles (300 Kilometers)
    As of 7/15/2018
Seating Capacity2 adults
Curb Weight1,960 Pounds (890 Kilograms)
890kg, car got 130kg fatter. Still quite
Tires155/70 13"
Conversion TimeStarted planning in 2012.. 2013 gas motor out
and electric in. Then ~4 years of idling. And
final conversion was in 1 year.
Conversion Cost+10 000 euros.
Additional FeaturesIt has sunroof and pretty good audio devices.
Also Grumpy cat hates your Prius.
The car was inspected succesfully in
11.5.2018. I drove 350km in two days and
rear shock absorber decided it was its time
to quit its job.. Now waiting for new shock
absorber to arrive. This one is a cheap one (I
just want to get as quickly as possible back
on the road), but I'm going to replace all
shocks and
springs with Koni absorbers and H&R springs
later in the autumn/winter 2018.

22.5 Back on road. 700km driven and around 70
euros saved on gas.
