Rated power can be different from average power while the appliance is running.
Voltage, automatic on-off cycling and equipment condition can change real use.
Use this as a budget estimate. The appliance label, how often it runs and all charges on your tariff determine the real bill.
Battery energy added is increased for charging losses, then multiplied by monthly sessions and the entered home tariff.
Use the usable battery capacity, average state-of-charge increase and wall-to-battery losses reported for the actual vehicle and charger.
Do not multiply full battery capacity by every session when most charging starts from a partial state of charge.
Energy (kWh) = watts × quantity × hours × days × operating factor ÷ 1,000
