Electricity costs

assume $0.1/kWhr = 10 cents per killowatt hour

Del Sol

using the performance documented at http://www.evalbum.com/1250

=> 0.5 kWhr/mile \times $0.1/kWhr = 10 cents/mile

batteries = 18 US Battery US-8VGCHC, 8.00 Volt, Lead-Acid, Flooded = @ $170 each => $3060

If batteries last 600 charge and recharge cycles and you get 50 miles per cycle =? $3060/600/50 = $0.1 /mile

Then total cost per mile is $0.2.

A posting about miles/charge

70 miles at highway speeds in my force (at 2100 lbs) (a very very efficient ev) is about 52 100ah Lifepos i can do a tad more than 70 (im in waterford, mi) in the winter that goes down 20% with having to use the heat and the cold.

Trackers are not as efficient. You are going to need 48 200ah lifepos to get 70 miles at 60mph no heat.

Heres my math 350wh a mile x 70 miles 24500watts (24.5khw)

24.8 /.8 (to get life from the cells) 80% dod) = 30.6 wkh

30600 / 3.2 (nominal on lifepo4;s) = 9562 / 200 = about 48 cells.

Now, this gives you really nothing in case something happens and you need to go 75 miles so perhaps 52 cells would be better.

so 48 x 200 ah cells = about $12500 shipped

Assuming you can mount them you would have a 70-80 mile ev depending on speed.

I still think you need 52 if you want to drive in the winter and use heat.

make it $13,500 ish for 52.

An example of how efficient the force is:

I have a saturn as well. Its about the same weight.

I use 48ah round trip 54 miles (45mpg max) down woodward and back to waterford in the summer no heat in the force.

With the saturn I use 66ah round trip (same speeds same route same careful hypermiling driver)

Id say the tracker would be 2x the force for watt hours a mile.
