KWh
KiloWatt Hour. It’s a unit for measuring how much electricity (or energy) you’re using and the size of a battery is measured in kiloWatt hours. For example the least expensive battery on the Volkswagen ID.3 is 48 kWh, which means it can store a maximum of 48 kilowatt hours of electricity. It’s time to stop thinking about your miles per gallon (MPG) and start thinking about ‘miles per KwH’.
