FYI, the present NiMH EV1 range is up to 150 miles on a
very good day, not 180. But the recharging time is not
at least 6 hours... with a 240 volt charger, it takes
3.5-4.5 hours for a full charge unless temperatures are
very hot. On my trip to Montreal/New York, average trip
segments of 120 miles were separated by 2.5 hour recharge
stops.

While I definitely share your enthusiasm for high power
faster chargers. But personally, I'd be kidding myself to
say that 50 range miles is all I want from my primary car.
I use it a lot, but the 65-70 mile range of my Ranger EV
is not always on the winning side of convenience.

Faster charging is not a direct substitute for more range.
On the Montreal trip there were several segments where the
trip simply wouldn't have been possible in a car that couldn't
go the 100 or so miles between available recharge stops. Along
I-76 through Utah there's a stretch 105 miles long where there
literally is not a single service facilty let alone available
electricity.
