| Other Notes: | | The car was already converted when I bought it. It was using lead acid batteries. I retrofitted the batteries from lead acid to lithium and upgraded the speed controller, DC-DC converter, and gauges and installed a battery monitoring system for the new lithium batteries. The car uses 2 Ah/mile average at freeway speeds between 65 to 75mph. The car could go more than 90mph. I hit 90mph and still had more acceleration.
- 10/1/2010 upgraded the charger to Elcon 5KWh charger.
Top speed reached 100mph. Update on 5/8/2011, total EV miles with lithium batteries = 18k miles. Drive 100 miles a day commuting to work. Estimate 25K miles a year. 8/31/2011, EV miles = 24.5K. The car spent four weeks in the paint/body shop getting make over. The new color is championship white. The car looks new from the outside.
Update on 11/03/2011
CellLog 8 Battery Monitoring System = Works great, so far no issue, protects all the cells from overcharging, and of course from overdischarging as the throttle is reduced from max 100% to 50%. It's up to me how far I have to drive the car slowly to a safe place as I still could drive it in this mode, and the cellLog 8(s) would beep non stop. The cellLog 8 itself is very accurate and reliable.
LiFePO4 batteries = All 44 cells perform the same as new. The capacity remains the same.
EV Display (new version) = Pretty accurate tracking the battery pack state of charge/discharge. It's not expensive for all the features that it has. I recommend this EV Display.
MOTOR up-to-date mileage = 40k miles, 10k miles with lead acid batteries. 30K miles with LiFePO4. Motor Still runs strong as the same performance when was starting with a fresh LiFePO4 pack. The Advanced DC motor brushes should last about 100k miles. By then I should be able to feel the difference in motor performance.
1231S Curtis controller = 30K miles, still runs smooth
1231S is a 750A factory modified version.
Curtis controller is air-cooled and super reliable. My car odometer has logged 30k ev miles to prove.
Kelly DC-DC converter = Still works when the key ignition is turned on. I have it connected to a 20A, 5-220VDC solid state relay. This solid state relay so far could handle the inrush current of the electrolytic capacitors inside the Kelly.
Elcon PFC5000 = Still charges the batteries every time is plugged in to the wall.
PB-6 throttle = About two months ago, the accelerations felt jerky when pressing the pedal. Suspected might be the pot inside the stainless steel box went bad. Replaced the 5K pot inside the box with the OEM part which is Curtis part number. The motor runs smooth, even smoother than before. The jerkiness was caused by a bad pot. The bad pot had about 36k ev miles. Let see how many miles this replacement OEM part will get before starts acting up. On 1/30/2012, the motor stopped spinning while driving on the freeway at 70mph. A strong burning smell came from the motor. Had to tow the car back home. Inspected the motor and took some pictures. One pair of brushes were disintegrated, only the brush wires left. Replaced with a new motor (the same ADC). Made some improvement by relocating 5 cells on top of the motor to the back. Had the car back up and running on 2/27/2012. The motor had 46K miles on it when the brushes were worn out.
The brushes of the 8" ADC motor would not last up to 100K as mentioned above when running at a higher voltage than it is rated (72-96V). The motor is also being stressed due to the use of lithium batteries as I could drive up to 100 miles straight at freeway speeds. The motor brushes would last much longer if I ran at 96V pack of lead acid batteries as I would have to recharge the batteries after 30 miles of driving. 6/23/2012, EV miles with LiFePO4 = 45,019 miles. I use EV CLUB site to accurately track my ev miles. https://secure.mr2ev.com/evclub/
