Here's the car on day one.
OwnerGavin Shoebridge
LocationNew Plymouth, Taranaki New Zealand map
Web/EmailWebPage email image
Vehicle1987 Mitsubishi Tredia
Classic 80's square shape. Excellent Brickodynamics. :)
MotorAdvanced DC FB1-4001A Series Wound DC
I think the motor install was the hardest part of the whole conversion. Once that was complete the rest was easy.
DrivetrainOriginally a 1.6 Litre, 4 Cylinder Planet Killer, Front Wheel Drive.
ControllerCurtis 1231C
The Curtis controller gives excellent performance for low cost and I've decided to love the noise it makes. :)
Batteries12 Hella Endurant, 12.00 Volt, Lead-Acid, Flooded
85 A/hrs, Deep Cycle, 515 CCA.
System Voltage144 Volts
ChargerZivan NG3
I used to have a charger-per-battery method with a 32-pin plug but it was too slow. This Zivan charger takes only 2hrs 45mins from 50% empty to completely full. Love it!
HeaterA standard 230V household ceramic heater element has been modified to fit and is installed. It works ok and takes the chill off the car though next time I'll use a 110V US element and get it blazing hot. I measured a max of 60 deg C (140 Deg F) coming out of the vents after a few minutes.
DC/DC ConverterThermaltake 450
I modified a 450W computer power supply to put out 12.7 volts. It's replaced the accessories battery completely. I wish I'd done it from the start!
I've included instructions on my website for those keen to copy me and save money on a DC/DC converter.
InstrumentationA digital display 500A Ammeter and separate 200V Voltmeter are installed.
Top Speed85 MPH (136 KPH)
It sits at 62mph effortlessly. Must be because the battery pack is fairly small & light.
AccelerationExcellent acceleration under 35mph. For example 0 to 35mph in 2nd gear takes only 5 seconds on a freshly charged pack! I wasn't expecting acceleration that good.
Range50 Miles (80 Kilometers)
Range is not important as our town is small and so is my 144V battery pack.
I estimate I should be able to squeeze a maximum of 50 miles from my little pack but that would be completely flat.
EV Miles
Start:118,396 Miles (190,499 Kilometers)
Current:120,914 Miles (194,550 Kilometers)
Total:2,518 Miles (4,051 Kilometers)
    As of 9/30/2008
Seating Capacity4 adults
Curb Weight2,600 Pounds (1,181 Kilograms)
1180 Kilograms. That's exactly 200 kilograms (440lbs) above the original weight.
TiresI had 2 new tyres put on the front. They were the cheapest I could find in the whole town.
Conversion Time9 months of occasional weekends. About 4 months of that was just waiting for things/people/money.
Conversion CostApprox $9000 USD. Quite high but a lot of that figure is just shipping and taxes.
Feel free to check out the webpage for photos & videos of the EV Conversion process as it unfolded!
