Re: [EVDL] commuting costs

For most EVs, the cost of battery depreciation dwarfs the cost of energy.
It varies with the battery type, type of vehicle, how you drive, and how
well you maintain the battery.

With what batteries cost these days, 6 cents per mile is about as cheap as
it gets in a small car, and 15 to 40 cents per mile wouldn't be at all
surprising for AGM batteries, larger vehicles, etc.

About 8 years ago, I calculated the cost per mile of gel batteries for a
2100lb Solectria Force (Geo Metro) at 20 cents per mile. For Trojan 27TMH
batteries I figured 8 cents per mile, and flooded golf car (if they would
fit, which they wouldn't) would have been about 4 cents per mile. Remember
these are at 8-years-ago prices for batteries.

Minor correction : Battery costs are four times AS HIGH, or three times
HIGHER.

The difference isn't just academic, there's an accuracy issue here. Misuse
and misunderstanding of these two non-equivalent English expressions is
pretty common. It may be safer to avoid using "as high as" or "higher than"
altogether when explaining EVs' capabilities to the public - or anything
else, for that matter.

No doubt about that!

Good catch, David. But you missed the huge math error, so there!

Actually, I can claim I put these errors in on purpose just to see if anyone is paying attention

Lee, do you have a file that you pull all of these quotes from? If so, I'd like a copy. (I'm not saying that I need a different quote line ;-) )

I glean 'em from all over the place. I attached a few files with them
that I have on my computer. Others are from books, or calendars, and
various other printed sources.

Actually, I'm flattered that anyone would want to quote me!

Sorry gang; I got bit by the new EVDL listserver again. I see "From: Tim
Humphrey" so I think it is from him. But when I hit "Reply" it goes to
the EVDL, because Tim sent it through the EVDL, not directly.

At least we know that attachments are now being properly stripped.
