Vehicle1976 Reliant Kitten Estate
Barn find. The car has been completely
rebuilt with a galvanised
chassis, twin circuit disc brakes upgraded
suspension, Can-based
wiring and so many micros I have lost count!
MotorKostov From a G-Wiz car that was modified for Top Gear! Separately Excited DC
DrivetrainStandard gearbox/transmission. Motor
drives through modified clutch plate. Gearstick still there so I
can select a lower gear for acceleration at busy junctions. Also
allows me to disconnect the motor from the drive train if necessary.
ControllerCurtis 1274
From a scrapped G-Wiz. The standard setup is
a good match for the the Kitten. Comes with
regen and economy mode and the various
safety interlocks.
Batteries48.00 Volt, Lithium-Ion
Lead acid removed. Now running 14x18650 based
13s8p LiiON PACKS. Cells from recycled laptop batteries. Each
pack has its own BMS and external current monitor that chceks that
the packs are charged/discharged at similar rates. 22x 2600F ultra
capacitors to help with regen and smooth
out heavy transients.
System Voltage48 Volts
Charger Eaton APR48
2x 750W 48v battery chargers (from a GSM
base station). These are due to be replaced
with 2KW versions when more Liion packs
are added. These supply 3-4 KW charging rates. About to be
upgraded to go higher with 3 phase.
HeaterTwo 12v hairdryers feeding demisters in the
dash.
DC/DC Converter
Separate 12v 18650 based li ion battery
with own charger.
Designed to run all the ancillaries for a
couple of hours.
Automatically charged when Transport
battery pack is charged.
InstrumentationDigital using Can bus for main dash and
control. RFID controlled power up. Fuel
gauge is a Chinese coulomb counter that
displays the volts and amps taken by the
motor, power consumed so far, and AH
remaining for the motor and individual
battery packs. Chargers have similar
meters to measure how much power has been
used to recharge the batteries.
Top Speed52 MPH (83 KPH)
Cruises comfortably at 30-40mph.
Hit a new top speed of 52!
AccelerationReasonable. Can improve by selecting 1st or
2nd gear and then doing a clutchless change
up.
Range40 Miles (64 Kilometers)

reduce weight and extend range. Did a 37 mile round trip with
power to spare the other day.
