Dfinitly, I have been doing some searching.
I found this 2 seater:
Electric Motorsport :: Electric GPR
60 Mile range (economy not performance) for $8500.
It is a 3.3kwh Lithium pack.
So this vehicle weighs in at 285 lbs without a driver. Giving it about 18 Miles/kw. This is phenomenal.
However, if you double the pack, you add another 90 lbs. What does that do to the miles/kw? It won't double it, as the added weight will cut into your range. A third pack and you have added 65% (about) to the curb weight.
Then add the weight of two more wheels, a larger frame, the seats (no matter how cheap).
Now, I was going under the assumption this would be a street legal vehicle capable of highway speeds.
I do believe you could make a beach style dune buggy for 12k, but I don't see a street legal car for anywhere close to that.
Unfortunately the only prices I have found are at Wiki, $2.8-$5/watt. So if we need 200 miles and can get 5 miles/kwh (the Th!nk City gets about 4mile/kwh but could be trimmed down some), we need a 40kwh pack.
At those prices, the pack would cost ... ok, those wiki numbers must be out of date. I can't see them costing as much as my math comes out to, or I am tired and have really messed up my math
I'll keep searching for some accurate costs of large lithium ion batteries.
Rob, if you see this, could you further define 'car' for us? Are you asking about a street legal, highway capable car, or something else?
