Battery capacity tells you how much energy an EV can store; range depends on how efficiently the vehicle uses that energy.
What to Consider
Two EVs with similar battery capacity can have different ranges because mass, aerodynamics, tires, drivetrain and auxiliary loads affect efficiency.
Practical Perspective
Temperature, highway speed, heating, air conditioning, traffic and terrain can materially change consumption. Ownership planning should therefore consider normal routes, charging access and usable capacity.
Expert Perspective
The U.S. Department of Energy's Alternative Fuels Data Center provides educational information on EV efficiency and charging.
