What do you mean by Nominal Capacity of an EV Battery?

Nominal capacity refers to the amount of energy an EV battery can store and subsequently release under optimal conditions. It serves as a fundamental indicator of a battery''s performance, providing insights into the driving range, efficiency, and overall capabilities of an electric vehicle. Nominal capacity is denoted in ampere-hours (Ah) or kilowatt-hours (kWh).
