[ausev] Fwd: Good sources to get started?

[Sarah & Erik]

A well built EV will take less than 250 WH/mile, a more common number
is probably higher than that, say 300-350. This is probably
appropriate numbers for around town use. Depending on aerodynamics
your highway energy consumption could be much higher, maybe twice that
at 60 mph.

To take a stab at whether lead acid batteries will work, look at the
total capacity which will be given at the 20 Hour rate, and multiply
by .57 to get how much energy you can count on at the 1 Hour rate.
Generally with Lead acid, aim for 50-60 % discharge on your normal
run. Sorry for the short email, feel free to ask questions if this
doesn't make sense.

Please feel free to pipe up if you think my numbers are bogus.
