Electricity consumption is, in fact, measured in killowatthours, i.e. the number of kilowatts per hour.
Home charging stations do not show the amount of energy supplied.
However, when you use a standard Electric Circuit charging station, you receive a receipt by e-mail that indicates the number of kilowatthours consumed. Fast-charge stations also indicate the number of kilowatthours supplied, but on the station display at the end of a charging session.
