|Location||Cairns, North Queensland Australia map|
|Vehicle||2003 Proton Jumbuck Ute |
Standard Proton Jumbuck ute, vehicle
basically a Mitsubishi Lancer front end,
assembled in Malaysia. Chosen for low
weight, good payload capacity,
|Motor||Advanced DC 203-4001 Series Wound DC|
Standard ADC 8 inch dual shaft. Brushes
advanced 7 degrees
|Drivetrain||Standard 5 speed gearbox, clutchless. Use |
2nd gear to 80kmhr then shift to 3rd.
Shifting easy, up or down no problem,
fingertip force only. Synchro's in box
make it smooth.
|Controller||Logisystems 750 amp|
Turned way back to max 300 amps, gentle
ramp. Previous setting (600amps) was a
real tyre shredder, de-tuned in the
Update: Swapped out linear for
logarithmic potbox, so much smoother on
takeoff, reversing not so inclined to
launch unexpectedly. All round better
performance. Made up heat exchanger for
water cooled controller - controller is
slightly warm to the touch after 20 km
trip at 100km/h, this is the way to go
for peak controller performance.
|Batteries||12 Haze Ultimate UL12-100, 12.00 Volt, Lead-Acid, AGM|
These are a budget AGM made by Haze
(Germany) in China. So far so good.
Dual auto/threaded post type lugs.
100Ah@c20,63Ah@C1. Good AGM's can
really pack a punch.
Update: These batteries are holding up
really well. I have not had them below
60% DOD, would have at least 100
charge/discharge cycles now.
|System Voltage||144 Volts|
Set to single voltage profile, with
custom made shunt type regulation for
each battery. So far pack is staying
perfectly balanced. Gentle profile
should prolong life of pack, charging
takes an additional 20% longer to full
than the 3-step profile. Charger still
pumps the amps in (17amps) up to approx
80% full, then floats off current at
Update: Balancing system working really
well, all cells within 0.05 volts after
resting overnight after fully charging.
Max shunt current 3 amps per battery.
|Heater||Tropical North Queensland... However |
retained air-con to act as window demister
in the steamy hot wet season here.
|DC/DC Converter||Meanwell (similar), EV-Power 350 watt|
Switch mode power supply set at 14.4
volts, 36 amps max. Charges a 12V 18Ah
sealed battery for usual vehicle loads
(lights, wipers, keyless entry etc.)
|Instrumentation||TBS E-Meter. Well worth the dollars.|
|Top Speed||90 MPH (144 KPH)|
140kmh easily, however amps were getting
up there and road was running out.
100km/hr highway speeds no problem, max
approx 120+kmh with present controller
|Acceleration||Awesome with higher settings on |
controller. 0-100km/hr in under 10
seconds. Now probably 15 seconds as
settings have been tuned down on
controller. Very dependent on battery
state of charge
|Range||60 Miles (96 Kilometers)|
40km driving like a maniac, 80km driving
like Grandpa. Comes down to speed and
terrain. Cant wait for some lithiums...
|Watt Hours/Mile||60 amps @ 60-70km/hr|
100-120 amps @ 100km/hr
Getting better with practice.
Update: Using tacho, ammeter, and gear
selection, once up to speed I can
achieve 1 amp per km/h on flat ground
|Seating Capacity||2 adults|
|Curb Weight||2,700 Pounds (1,227 Kilograms)|
1320kg all up. 200kg heavier than
standard. 370 kg payload. Ute drives so
much better with a bit of weight, too
skittish before. Weight distribution
perfect - 4 batteries over front axles,
8 in rear tray
|Tires||Crap, getting some good ones shortly. |
Lightweight alloy rims. Running at 40 psi
|Conversion Time||8 months waiting for parts, 3 weeks |
evenings and weekends to get it on the
road, BMS etc another couple of weeks part
time. Still tinkering and tweeking...
|Conversion Cost||AU$9500 plus car. Ordered parts ex USA |
when Aussie dollar was really good last
October, saved heaps.
|Additional Features||Power steering (on small 1hp permag DC motor, 3amps@144V), |
air-con. Daily driver for 40km commute, 70% at 100km/hr, 30%
city driving. Having a tonneu cover for tray made for
aerodynamic improvement, also plan on installing belly-pan
and blocking off grill. Impact cut-out switch, 12 volt MES
vac pump (ex Sweden) for brakes - super quiet, Andersen
battery disconnect. Liquid cooled motor controller. Huge EV
grin on driver.
|Awesome car. My diesel Nissan Navara feels prehistoric to |
