How much does it cost to charge an EV at home in Spain?

A home EV wallbox draws 2,000 to 7,400 watts on a single-phase connection (up to 22 kW on three-phase). Charging is where the tariff matters most: an EV shifts a big, flexible load onto your bill, and you get to choose when it happens. Charging overnight on an off-peak tariff, or during Spain's cheap solar-rich midday on an indexed one, can cut the cost dramatically versus charging at the evening peak. Set the hours and days to match your typical charging.

How we calculate this

kWh/day = (W / 1000) × hours
cost/month = kWh/day × (days/week ÷ 7) × 30.44 × rate
cost/year = kWh/day × (days/week ÷ 7) × 365.25 × rate

An EV is a big flexible load — charge overnight off-peak or at cheap solar midday, and the tariff makes or breaks the cost.

Frequently asked questions

How much does it cost to charge an EV at home in Spain?

A 7.4 kW charger running 2 hours a day uses about 15 kWh — roughly €2.80 at an all-in rate near €0.19/kWh, but far less on an off-peak or indexed tariff overnight.

When is the cheapest time to charge an EV in Spain?

Overnight on an off-peak tariff, or during the cheap midday hours on an indexed tariff when solar floods the grid. Charging at the evening peak is the most expensive.
