Electric car kW figures explained
The total battery capacity of an electric car is measured in kilowatt-hours (kWh or kW-h). This rating tells you how much electricity can be stored in the battery pack. It''s a unit of energy, just like calories, and one kWh is equal to 3600 kilojoules (or 3.6 megajoules). Unlike kW it is not a unit of power.
