kW
Kilowatt. This is a measurement of power, in a petrol or diesel car if 50mph is your speed then you have to maintain that for an hour to travel 50 miles. In an electric car 40kW is how much power you’re using and you’ll have to maintain that consumption for one hour to use 40kWh.
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’.
