I'm looking right now for a better motor & battery pack for the Karmann Ghia. I know very well that "More" is a slippery slope. I started with an electric bicycle in 1995 and step by step have moved up the vehicle food chain to have a car. Anyway.. the car as it stands is not fast enough nor enough range. I've been driving it for two weeks and it will make it to 40 miles/hr (eventually) whereas I have a bit of driving on a 45+ miles/hr expressway that must be traversed to get to the office. Further the range tends to be less than 10 miles (and that's with a 150AH battery pack so I'm thinking there's a weakness in the battery pack maybe). Anyway.. "More".
From looking at the EV Album listings the 120+ volt range will give this car enough pep to be reasonable and even with lead acid the range is respectable. If I can afford it I'll be getting a lithium pack however. And as noted before I'm looking towards making this car "more" enough that it might be my primary vehicle for around the SF Bay Area trips.
I have access to a Netgain Impulse9 motor at a great price. One of the Karmann Ghia's has this motor paired with a 144v 1000a controller (!!!!) and claims an 85+ miles/hr speed. That sounds, um, adequate. Sheesh over 100kw peak.
..but.. Maybe I'm over analyzing but I'm interested in the options. All vendors are being added to the vendor directory as I go..
Some of the vehicles use this...
Advanced DC #FB1-4001A http://www.evparts.com/prod-MT2120.htm
At 144 VDC, 28.5 HP continuous, 30.4 HP for one hour, 48.8 HP for five min., 100 HP peak
Price $1750.00 (motor only.. controller would be $1000 or so)
This series of AC motors looks interesting. The biggest one (AC50) is more powerful than the Impulse9, AND more compact, AND more efficient. It runs at only 108 volts max. It's over $4000 for the motor and controller. Oofda.
AC Induction Motor and Controller Kits
Electro Automotive carries Azure Dynamics (Solectria) AC motor systems
The AC24 is smaller than the AC50 above, less powerful, lower max amps, lower HP, and is a whole slew of parts that must be bought together at more $$$'s than the AC kit that EMS carries.
