|Location||Columbia, New Jersey US map|
|Vehicle||1988 Pontiac Fiero |
OK, so there's not much original from my 1988 Fiero. This is a ground-up EV project which may eventually become a plug-in hybrid. The concept is essentially the same as the Chevy Volt. However, since I decided I MUST use lithium Ion batteries, and they're so expensive, I'm also focusing on low weight and high efficiency
|Motor||ABM 4DGF132Md4 3-Phase AC|
This is a specially wound low voltage 3 phase AC motor
|Drivetrain||Custom single speed direct drive with a Gearbelt and 6:1 ratio. Solid rear axle with tandem rear wheels on a trailing arm.|
3 phase AC Motor Controller. Best in the business, IMHO.
|Batteries||30 Thunder Sky LPH200, 3.30 Volt, Lithium Iron Phosphate|
I finally gott a set of 200AH lithium ion cells. I'm very pleased with them. Internal impedance is very low, and the cells seem to stay in balance when new. I plan to add a cell balance circuit soon.
|System Voltage||100 Volts|
These are telecom/industrial chargers made by TDI power. Lightweight and high efficiency. 110 or 220VAC input, 54V/80A (2, one on each half of the pack)
|Heater||pair of hair dryers (series/parallel for low/high speed)doubles as defroster. Works very well.|
|DC/DC Converter|| |
The Vicor brick did not hold up, so I'm using a Syncor block now. good for 228watts, seems to be enough as long as I don't blast the radio on a dark rainy night.
|Instrumentation||digital panel meters for volts and amps. Rest is TBD|
|Top Speed||68 MPH (109 KPH)|
Geared and plenty of power for the top end of 68MPH.
|Acceleration||0-60 in 12 seconds|
|Range||90 Miles (144 Kilometers)|
90 miles and full performance as a pure electric with the new lithium ion batteries. I originally planned to add a gas engine and alternator to generate 13KW continuous, allowing for continuous cruising on gasoline.
|Watt Hours/Mile||280 Wh/Mile |
this is based on rough road testing. Hope to instrument the car soon and find a nice long level stretch of road.
|Seating Capacity||2 adults|
|Curb Weight||2,050 Pounds (931 Kilograms)|
this is my current weight for the finished car with lithium ion batteries.
|Tires||General Altimax 185/65R14|
|Conversion Time||3 years|
|Additional Features||The motor controller has Regenerative braking which works extremely well. I've tweaked the parameters for regenerative braking. The way I have it set up, it feels as though you're driving a car with a manual transmission in second gear. I can drive it to work (18.5 miles/30 minutes) without ever touching the brake pedal.|
Had to add motorized struts to raise and lower the gull wing doors. Eliminated the door latches and associated alignment problems. Also added a driver to activate the brake lights whenever the regen current is above 60 amps.
|I've got it registered now and started driving it to work. Check out my website for the running build diary. WebPage />
