| Motor | ABM 4 DGF132Md-4 3-Phase AC Semi-custom low voltage AC motor from ABM Greiffenberger used in the forklift industry. Bought from ABM Drives Inc. in Ohio, ABM P/N 191.635.000. With an 84V battery and 550A controller, each motor will put out about 45Hp. Peak torque is about 110 ft-lbs each. Max rpm is about 6000rpm. | ||||||||
| Drivetrain | Mid engine, Dual AC electric motors belted together and connected to a clutch and the original 5 speed transmission. | ||||||||
| Controller | Curtis 1238-6501 48-84V 550A 3 phase AC induction motor controller. One is used for each motor. | ||||||||
| Batteries | 14 Odyssey PC2150, 12.00 Volt, Lead-Acid, AGM Two strings of 7 in parallel. | ||||||||
| System Voltage | 84 Volts | ||||||||
| Charger | Manzanita Micro PFC-30 Universal input 30A in, 40A out | ||||||||
| Heater | None. | ||||||||
| DC/DC Converter | Curtis 1400E 72/96-1211 22A output | ||||||||
| Instrumentation | Speedometer Tachometer Main battery voltmeter 12V battery voltmeter Motor/Controller temperature Battery state of charge gauge Shift light (programmable) Check Engine light for fault codes All the instrumentation is OEM and driven through an opto-isolator by the Curtis 1238-6501 controller. | ||||||||
| Top Speed | 90 MPH (144 KPH) Not yet tested. Highest speed run so far is 90 mph and it was still accelerating pretty quickly. | ||||||||
| Acceleration | 0-60 mph in about 11 sec Will do a modest burnout in first gear. NEDRA SC/G record set on 17-Nov-07 with both battery packs in. I ran 4 runs with no charging (the fouth was just as quick as the first) and still could run over 20 miles afterwards. 1/8th mile: 11.409 sec @ 59.824 mph 1/4th mile: 18.028 sec @ 74.269 mph | ||||||||
| Range | 30 Miles (48 Kilometers) About 30 miles at 45-55 mph in stop and go traffic. | ||||||||
| Watt Hours/Mile | 370 Wh/Mile Measured at the wall for normal driving at 60 mph including full accelerations. | ||||||||
| EV Miles |
| ||||||||
| Seating Capacity | 2 adults | ||||||||
| Curb Weight | 3,780 Pounds (1,718 Kilograms) Front 1670 lbs, Rear 1710 lbs, Same 44%/56% weight distribution as original but about 1000 lbs heavier. | ||||||||
| Tires | Still what I bought the car with. | ||||||||
| Conversion Time | About 500 hours spread over 2 years. | ||||||||
| Conversion Cost | Total around $16k. Motors $1k each. Batteries $3k Donor car $4k Controllers $1k each Charger $2k Suspension and brake upgrades $2k | ||||||||
| This car was built using 84V AC forklift motors and controllers which are cheaper than some other AC options. I got this on the road for the first time in August 2007. Since then I have had to improve the motor mounts after the motors ripped themselves loose and replace the battery they damaged. I am slowly working on the rest of it, but driving it as I go. I have had some problems with the Odyssey 2150 batteries. I vented one when running around 1400A from one pack repeatedly for relatively short cycles (~30seconds) with short rests (~30 seconds). I also damaged one due to charging imbalances. I installed Rudman regulators on the front pack and the powercheq dc/dc balancers on the rear pack and have had no problems since. | |||||||||
