  I went to your site but I didn’t find the info that I have been wondering about.
  How much will it add to your electricity to charge up your electric car?

If you mean gm-volt.com, that site is not mine. Dr. Lyle Dennis runs it. I've just been a long-time regular visitor to it.

A full charge will be about 8KWhrs (assuming you didn't have any charge left over from your last use). Multiply 8 times your rate for electricity and there's the cost for a charge.

Of course, after the charge is used up, the range extender kicks in. You are not stranded after 40 miles.

Also, if you haven't already, I suggest you check out the forum portion of gm-volt.com (click "Forum" in the menu bar at the top the page). If you don't find the information you want somewhere in there, by searching it, you can always post a question. People there are eager to help provide answers.

If someone STEALS your batteries, just what MILEage does the RANGE, ahem, extender do BY ITSELF?
