What will charging cost you?
Four quick taps. You see your yearly cost at home, the cost per 100 km and the saving against petrol and diesel. Your number is only asked for at the end, if you want a price.
A Tesla Model Y doing 15,000 km a year on a night rate: about €407 a year at home, against about €1,783 for a petrol car.
How this is worked out
The energy is your car's real-world use per km, plus a tenth for what's lost while charging. The unit rates include VAT: a standard 24-hour rate of 34.38c a kWh, a night rate of 15.42c, and an EV tariff's cheap window at 8.84c. Standing charges are left out. Petrol and diesel are at pump prices of about €1.98 and €2.15 a litre. It's a guide to plan with; your own bill has your rates.
How it's worked out
A car's real-world energy use per km, plus a tenth for charging losses, times the unit rate. A Tesla Model Y uses about 160 Wh a km, so about 17.6 kWh from the wall per 100 km. You rarely charge from empty: most nights cost the price of the day's driving.
