[RE-wrenches] Lithium-ion battery charging

Wrenches
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.
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?
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.
Thanks for some clues
