Energy added to the battery
A 60 kWh usable battery charged from 20% to 80% gains 36 kWh before charging losses.
Supply energy can be higher
The charger may draw more from the supply than the battery stores. AutoCifra lets you choose a loss assumption instead of forcing one figure.
Price matters
Home and public charging can have different p/kWh prices.
