<DIV><FONT face=Arial size=2>To further muddy the waters, I have recently seen
the approach to quantify electrical power performance in terms of
horsepower. </FONT></DIV>

<DIV><SPAN class=031553416-14032011><FONT face=Arial>I am researching a GT PV
installation to power an EV charging station at a new car dealership nearby.
After researching l-ion technology and charging information on the www, I see
that most references to l-ion and EVs in general refer to battery capacity in
kWh instead of Ah. </FONT></SPAN></DIV>
<DIV><SPAN class=031553416-14032011><FONT face=Arial>Is kWh the new standard
for battery propulsion in cars or is it used muddy the conversion
from Ah similar to the cold-cranking amps standard for starter
batteries?</FONT></SPAN></DIV>
<DIV><SPAN class=031553416-14032011><FONT face=Arial>I know kWh battery
capacity could be calculated assuming a constant charge/discharge rate
but cars will seldom be operated at a constant discharge
rate.</FONT></SPAN></DIV>
<DIV><SPAN class=031553416-14032011><FONT face=Arial>Thanks for some clues
