| Vehicle | 1984 Porsche 944 Named after my dad who is from Stuttgart. I drove the 944 as gas for a few months and then converted it over two months in Oct 2010. I did the electrical myself and had another shop make the battery boxes and mount the motor. We cut out the trunk area where the spare normally is and a little of the front frame area behind the bumper to add the batteries (7 in the front and 17 in rear). I have about $15k in parts and at least $5 in time in this project. This was our show car in two conventions held at the CDA Resort r- charge.net It has a full body wrap that always causes everyone to look while driving and come over in parking lots. I have all the power I need. Clutch is removed. Has good snow tires with studs, which I drove daily through the winter in snow (was good to have weight in back for winter). | ||||||||
| Motor | Netgain Warp 9 Series Wound DC | ||||||||
| Controller | NetGain Controls Warp 9 | ||||||||
| Batteries | 24 Trojan T-105, 144.00 Volt, Lead-Acid, Flooded With hydro caps. I never had to replace the water in 1.5 years of usage (driven daily). | ||||||||
| System Voltage | 144 Volts | ||||||||
| Charger | Renaissance RC-20A144 The Renaissance Charge charger found at r-charge.net allows me to keep my batteries and actually gain in capacity over time. When I first got the batteries in Oct 2010 starting voltages on the batteries fully charged were 163 and have now risen up to 193V. This means I can drive 10 miles and my resting voltage will still be considered fully charged. | ||||||||
| Heater | Used water from controller into the heater core which is enough to keep the frost off the windows in colder temps. Park inside always. | ||||||||
| DC/DC Converter | Not used. Use battery pack which works fine unless temp is 0F. | ||||||||
| Top Speed | I don't have anywhere to test the top speed. I wouldn't care to push it past that speed. | ||||||||
| Acceleration | I usually start it in second gear and can lay rubber in second. I don't want to push the 944 transmission though. | ||||||||
| Range | 80 Miles (128 Kilometers) In warm temps fully charged driving 55 mph. | ||||||||
| Watt Hours/Mile | I typically drive the car at around 80Amps average in the city and hyway. Only once pushed it 600Amps for extended time to see what it could do up the mountain. | ||||||||
| EV Miles |
| ||||||||
| Seating Capacity | 4 adults. Interior not modified beyond behind the back seat. | ||||||||
| Curb Weight | 0 Didn't check the final weight. We removed the gas motor parts, spare tire and added 100 pound motor, battery frames, 1500 lbs of batteries so it is about 1000 lbs over original weight. | ||||||||
| Tires | Regular | ||||||||
| Conversion Time | 100 hours approx. | ||||||||
| Conversion Cost | $20,000 | ||||||||
| Sold at r-charge.net | |||||||||
