Anyone have any idea how many kWh of charge is required for the
"electric range" of 40 miles?

From the chevy web site, it looks like ~ 13kwh.
That's from their $1.50 a day and 12c a kwh.

<http://www.chevrolet.com/pages/open/default/future/volt.do>

But, I hear the Prius's batteries tend to become unbalance after a few
years, and they need to be painstakenly charged and balanced.

I'm not convinced yet.

BTW, the Volts battery capacity is rumored to be between 25% and 75% of
the actual cell capacity. Otherwise the batteries will not last.
Probably due to heating during discharge (25%) and heating during charge
over 75%.
Wonder if they are still having 'Thermal' Events' ;)

I smell a business opportunity for a younger Techie.

In a few years there will be a supply of these things around that will
not have a market value that exceeds the cost of a new set of
batteries. A replacement power system that costs less than a battery
set may do well.

Watch out for new laws that may restrict such things. A niche may
exist under all circumstances. Any one for Steam Power? After all the
Stanley Steamer held speed records for a long time!

I suspect it costs more per mile to operate electrically than via
gasoline. But I can't find anything on the Volt website other than
obfuscated "specifications".
