Motor | HPEVS HPEV AC-50 3-Phase AC | ||||
Drivetrain | Five speed | ||||
Controller | Curtis 1238-7601 | ||||
Batteries | 32 160 AH, 3.20 Volt, Lithium Iron Phosphate Bestgo From The Electric Car Company | ||||
System Voltage | 96 Volts | ||||
Charger | Quick Charge SCPX9620 Controlled with solid state relays | ||||
Heater | 1500W heater blower from Harbor Freight. I run the blower 300 cfm from a 110V inverter and the heat element direct DC from the traction pack. I used a SSR to control the DC current (~10A) from the 110VAC control. | ||||
Instrumentation | Intellitronix WebPage /> Torque App WebPage | ||||
Top Speed | 70 MPH (112 KPH) | ||||
Acceleration | Not a priority, but feels pretty good. My car wasn't running when I started, so I have no reference to the ICE. It is way better than my wife's Pirus. | ||||
Range | 70 Miles (112 Kilometers) My goal is a 44 mile round trip. So far, I have gone 25 miles on approximately 30%. I think when I get the pack tuned in with my BMS, a 50 mile daily trip will be pretty easy with a 30 or 40 % margin. | ||||
Watt Hours/Mile | 310 Wh/Mile At 65 MPH, my car pulls 210 amps At 45 MPH my car pulls 120 amps | ||||

Seating Capacity | 4 adults | ||||
Curb Weight | 1,836 Pounds (834 Kilograms) Goal is to only be over the factory weight by a couple hundred pounds. Need to go by the scrap yard scales. | ||||
Tires | Economy | ||||
Conversion Time | Weekends from Feb to Nov 2012 (trouble getting parts) A LOT of time waisted to get batteries and charger from BestGo. | ||||
Conversion Cost | An embarassing amount, but not rediculous, including buying and fixing the car as well as a few new tools along the way | ||||
Additional Features | Using an Orion BMS with an OBD2 BT adapter to get my display over my Android Phone with the Torque App. | ||||
I bought the car for $700, but the transaxle was in the front seat. I found out when I got the car home that VW's are famous for having riveted differentials that come apart after 100k miles. I cleaned up all the gears and upgraded the dif with an ARP bolt kit. Update - It is taking much longer to get parts than I expected. Update2 - The car is almost together 10/2012. I'm having a lot of trouble with my BestGo charger. Absolutely no support from BestGo (China) with likely a faulty charger. As soon as I get the charger situation resolved, I'll be driving it to work. I did manage half way around the block, but without a charger, I'm sacked. Update - November 2012 only thing left is to connect the relays to control the charger. I ditched the CAN controlled charger after two junk chargers sent from BestGo. I found solid State Relays to work with the Orion BMS to cut off the AC to the charger and properly sink the DC to cut off the contractor to prevent over and under voltage to the batteries. I wasted a lot of time with BestGo. Doing it over I would choose different batteries. I'm not sure about my plate and hub either. My test runs have pulled a lot of amps. I did notice that a short run with regen brake nearly balanced my cells. I think this is going to be a great car and on going restoration project. Hopefully I'll be able to update on the tax benefits in a couple months. Update - March 2013 I had a bad vibration so I took everything apart and found a problem with my hub. I'm still waiting for a replacement from TECC. I also found four bad BestGo cells. Those cells had bad Voltage sag and higher than average (higher than spec) internal resistance. BestGo is sending replacements on the next slow boat. I also found that there is no tax break for us DIY'ers. That ride stopped in early 2011. To do it again, I would probably pick a nicer car to start with. I like the small convertible, but I did spend some time and money to fix up this car. The positive side to an old VW is that there are tons of parts available. If I tried to fix up an old Toyota, I doubt that I could find the parts outside of a junk yard. Trust me, those parts usually take some time to gather and clean up and they aren't new and sometimes aren't cheap.. Update (July 2013): I found the main source of vibration to be the front wheel bearings. After replacement, the car is very smooth and more efficient. My round trip commute uses about 40% of total 16KW pack @ 60 MPH in fourth gear the whole time. Update (August 2015) my main summer commuter. Moved to Birmingham, AL with more hills, but a slower and shorter commute. I have top speed on my current commute of 45MPH with few stop lights. Total commute time is about 15mins one way. Total trip is about 20% of total pack. |
