| Vehicle | 1984 Pontiac Fiero SE | ||||||
| Motor | Advanced DC FB1-4001A Series Wound DC | ||||||
| Drivetrain | Original 4 speed trans axle with electric motor replacing the gas engine. | ||||||
| Controller | DC Power Systems DCP-600 Raptor | ||||||
| Batteries | 20 Trojan T-125, 6.00 Volt, Lead-Acid, Flooded 235 Ah each. Battery age is first quarter 2003 batteries (getting really old!). | ||||||
| System Voltage | 120 Volts | ||||||
| Charger | K and W BC-20 BC-20 is 108 volts and with the LB-20 booster transformer it outputs 120 Volts | ||||||
| Heater | Proportional Temperature Controlled Thermistor Grid | ||||||
| Instrumentation | A) Speedometer B) Tachometer C) Traction Voltage D) Traction Amp E) Accessory Volts F) E-Meter G) EV Dash | ||||||
| Top Speed | 85 MPH (136 KPH) Top speed listed is the top speed on the speedometer. Using radar on a closed track by the previous owner the car has clocked over 112mph. (Batteries were NOT happy though.) I would say the usability speed/power is approx 75 MPH. Anything after that speed take time to achieve. | ||||||
| Acceleration | Using only 2,3 and 4 gear (normal use) 0-60 is about 25 seconds. See the stats image for all of the performances. | ||||||
| Range | 45 Miles (72 Kilometers) I needed to update this because after my cleanup projects of the batteries and adjusting some settings on my eMeter, I am now getting different results. Consistently get 45 Miles at 45 mph and 40 miles at 60 mph. I believe how I have the eMeter programmed now, it is more precise. The battery pack is 2003 First Quarter Stock, so its is almost 7 years old now. This measurement is only to 50% DOD. | ||||||
| Watt Hours/Mile | 400 Wh/Mile This measurement is the wall to wheel measurement with the K&W charger (which as far as I can tell is probably only 50% efficient with the LB-20). 13 Amps from the wall and only 6 amps going into the battery. | ||||||
| EV Miles |
| ||||||
| Seating Capacity | 2 adults | ||||||
| Curb Weight | 3,400 Pounds (1,545 Kilograms) Currently 500 lbs heavier than a stock Fiero. But the suspension and brakes have been upgraded to compensate for the extra weight. | ||||||
| Tires | Goodyear Invicta Need new tires now, the Invictas are getting old. Need to research whats the best LRR tires now. | ||||||
| Conversion Time | Previous owner took 6 weeks, evenings and weekends to do the initial conversion. | ||||||
| Conversion Cost | For everything, including tools, optional metering, suspension and creature comforts - $10314.73 Non-EV Stuff and above and Beyond EV Stuff: PISA Wrap Around Dash - $1325 Automatic Top off Watering System - $1000 (Removed) 12 Volt AGM Battery - $50 Automatic Smart 12 volt Charger - $50 LED Lights - $130 Palm IIIc (& accessories) - $40 Coming Soon a Capacitor Bank - $500 | ||||||
| Nov 07 : The LED lights I ordered have helped. I don't hear as much whine in the DC/DC converter. Its actually almost non-existent now. The replacement flasher didn't work so for now I have to manually blink the turning signals. I wish I would have done an amperage check to see how much of a difference it made switching to LEDs. I also have a 5 farad capacitor in place of the dead 12 volt battery. I still get power sags when I first take off, it just isn't as much as before. Nov 07 : I had one battery go bad. The battery developed corrosion under the terminal connection and over heated and melted the terminal while I was driving. So I am currently driving the car on only 19 batteries. I don't see any mileage difference with one battery short. But I still plan on replacing the one bad battery. Dec 07 : I have the one bad battery replaced and I never did really see any difference with 1 battery short. Battery prices have really jumped recently. I paid 125 dollars for a new Trojan T-125. But once I got the new battery in place, I have driven the car pretty lightly to break in the new battery. I have been getting over 60 miles regularly. Jan 08 : I just had the car painted Glossy Black. It now looks like a new car again. If you are going to get your car painted be sure to check what they paint. It turned out that the door jams were extra. Feb 08 : I just bought a 12 volt AGM battery. I took out the DC/DC converter and 5 farad capacitor. I also bought a 12 volt smart charger to charge the new AGM battery. Since the 12 volt system is now totally separate from the main pack. Preliminary testing shows about 1 to 2 mile increase per charge but I am still going to call it 60 MPC. Apr 08 : I just had the rear brakes totally replaced. They were starting to scrape the rotors. The calipers were getting shot and the rotor was worn down past usability. The brakes have actually been dragging causing the motor to work harder than needed. At 45 MPH I have seen amperage drops of 10 to 15 amps. Thats a HUGE drop! I will start keeping track of mileage for the month do recalculations of mileage and KW/Mile. May 08 : I just completed a highway speed test. Before when the brakes were bad, I had such high amp draw that its highway mileage was cut in half. Now that the brakes are fixed, I just averaged 61 MPC averaging 60 MPH. I was doing 60 MPH and only pull 115 amps in 3rd gear. Before it was almost 200 amps to do 60 MPH, so a huge difference on brakes. People check your brakes before they start making noise! Jun 08 : I picked up on old PDA and got EVDash installed on it and have it interfacing with the E-Meter. I am hoping to log my drives and data and how some comparison data to see. Another cool feature of the EVDash program is alerts to let you know when low voltage (from sag) and high amps occur, so you have some sort of audio indicator to let you know to pull back some. I have also been playing around with different driving techniques and also building a cheap DIY AC system using a cooler and a bilge pump. Jul 08 : I was on vacation most of the month but I have gotten accelerometer data using Dynolicious program using an Apple iPhone. It it suppose to be pretty close to a full dyno run but in real world usage. Here is what the car did: Acceleration (starting in 2nd gear and WOT after 5 seconds): 0-10 : 1.72 Sec 0-20 : 4.21 Sec 0-30 : 7.34 Sec 0-40 : 12.06 Sec 0-50 : 19.61 Sec Didn't make it to 60 ran out of road, will do more runs Elapsed Time : 60' : 3.84 Sec @ 17.7 MPH 330' : 10.21 Sec @ 35.8 MPH 1/8 Mile : 15.64 Sec @ 44.3 MPH 1000' : 20.48 Sec @ 50.8 MPH 1/4 Mile : 24.47 Sec @ 57.2 MPH Miscellaneous Data : Max Speed Achieved : 57.4 MPH (got close to 60 but ran out of road) Max Acceleration : 0.36 G's Peak Horse Power : 50 HP (At the wheel HP, not Flywheel like gas car) Passengers : 2 Weight Used : 3900 (2 heavy passengers, so compensated extra for weight) Temp : 95 Degrees I've got video of this run, they are post on my website, next time I will also do the run with my EVDash program running in the screen shot to see Volts and Amps pulled. You can also see these videos on my YouTube WebPage . Aug 08 : I just got my own digital camera so I will do a few more videos and post them up on my YouTube site. Nothing much else going on this month. Sep 08 : I just finished taking out all of the battery racks, grinding them down and repainting. I painted the racks with bed liner spray. I am hoping to cut down on the corrosion I clean up every month. I also took out the Battery Watering system to see if that is what is causing all of the corrosion that I get every month. While I was cleaning the battery racks, I also took out the battery heater system. It is not needed in Texas, it hardly ever gets below 50 degrees and the car is always in the garage. I also built 15 battery desulfators and installed them onto the battery pack. I will be recording voltages over a few months to see if the batteries start recovering. I am updating my website to have pictures of the cleanup and before and after pics. Oct 08 : The desulfators have worked well, the batteries are taking a better charge. I've even had to adjust the charger because the batteries are working better. I also ordered a Zivan NG3 charger. Since the batteries are responding well, I think a high efficient charger like the Zivan will keep the batteries alive even longer. It is getting close to two months and the batteries are still clean, it was definetly the battery watering system that was causing the problems. So its been great having the batteries stay clean. Nov 08 : I have lowered my miles per charge down to 45 miles (was 60 miles). After my cleanup project and me messing with the programming of the eMeter, I think it now better represents how the car is performing on its almost 7 year old batteries. This month is the 2 month mark of my desulfators and I am pleasantly surprised, all but 5 of my batteries have reached the 100% charged voltage of 6.37 volts. Two of those batteries are at 6.36 volts which is 98% charged, so there is still good hope for these two batteries to hit 100% charged. Another two could possibly hit 100% if given enough time (they are at low to mid 90's%) and I will be watching that, there is still hope for those two. The last one is really weak, I don't think it will fully recover, it is sitting about mid 80's on its percent of charge. All of the batteries will remain on the desulfators, but I think that battery is just not going to recover. Dec 08 : The Desulfators have been on my battery pack for 3 months now. With the batteries being healthier, I have been turning up my charger's voltage more and more. My pack now hits full charge voltage. As expected from the weaker batteries, they haven't recovered any further. It does look like 1 lb of lead per day on the desulfators. I just started some aero dynamic changes to the car, I will probably finish those up in Jan 09. I started using my heater in the car this month but it hasn't really heated the car up very well. Will probably look at that some time to see if there is a problem or just needs to be upgraded. Future : My next project for the car will be a full Belly Pan. I have a cardboard one started but I need to pick up some corplast from somewheres. I will also like to redo the front grill so it directs the air flow below the car. I would also like to do the side skirts for the back tires. Also thought about shaving off the side mirrors and moving them inside of the car. Anything to help the aerodynamics will help the mileage. Jan 09 : Got a new project for a performance enhancment. I helped a friend wire up a small bank of capacitors into a Ranger EV. I did the test driving and could actually feel a performance gain. So I decided to build one for my car but I will be building a larger capcitor bank. Hopefully I will have good news to report back on that at the end of the month. I'll be sure to take lots of pictures. Many thanks to North Texas Electric Auto Association ( NTEAA WebPage ) for all the help and tips. | |||||||
