LocationBudapest, Central Hungary Hungary map
Vehicle1993 Citroen Xantia
ICE was 1.8 l petrol engine, 75kW.
Hidropneumatic suspension I. generation.
Servo brake and servo steering system.
MotorKostov DC 6,3/7,5/14 11 Series Wound DC
11" Balkancar forklift motor from 1970.
93 kg 6.3 kW at 80V 1400 RPM. The
4 poles in series have been connected
in parallel (2-2)for higher speed. The
brushes are also advanced. The original
transmission is assembled by home made
adapter plate. The system is clutch-
less. The original clutch plate is used
for coupling.
DrivetrainManual 5 gears
ControllerOpen ReVolt 500A
Planned to build. FETs, capacitors and
freewheel diodes are purchased for PWM
controller.
Batteries45 Tornado, 3.20 Volt, Lithium Iron Phosphate
100Ah cells form Tornado Science Groups
Limited (tnd-battery.com)
System Voltage144 Volts
Charger
Home made is planned. Analog distributed
BMS.
DC/DC Converter
Not decided. Original 12V lead acid is
still used.
Top Speed80 MPH (128 KPH)

Curb Weight0
The original weight was 1250 kg. I hope
the original weight will be kept.
Conversion Timestarted: 18.04.2012
Additional FeaturesThe hydraulic pump for suspension,servo brake, and the
servo steering originally were driven by belt from ICE. Now
an auxiliary permanent magnet DC motor is used. Brushed DC
motor (from treadmill). It is 180V 3LE at 4000 RPM. The belt
gear is 11:6 having enough torque for 175 Bar
pressure(tested an worked from 24V).
Under construction
02.10.2012 The project is running. The series wound DC
attached to the transmission gear by home made adapter
plate and mounted into the car. The hydraulic pump assembled
with auxiliary DC motor.

25.04.2013 The 40PCS of batteries arrived. The bouild of BMS
and Charger is in progress.
