EV Home Charging Calculator

The cost depends on your electricity tariff, battery size, and how often you charge. On a standard day/night plan, a typical 60kWh EV charged from 20% to 80% costs roughly €6–€8 per charge at night rates. With an EV-specific boost tariff (as low as 5–9c/kWh), the same charge can drop to €2–€4.

Use the calculator above to get a personalised estimate based on your exact provider, tariff, and driving habits.

An EV boost rate is a special discounted electricity rate offered by some Irish providers specifically for EV charging during off-peak hours. Typically this window is 02:00–05:00 (though it varies by provider), and rates can be as low as 5.45c/kWh compared to standard day rates of 30–40c/kWh.

Providers like Pinergy, Bord Gáis, Electric Ireland, Energia, and Flogas all offer EV-specific plans with boost hours. Select a provider above to see the interactive rate timeline.

In most cases, yes. If you charge at home regularly (2+ times per week) and can schedule your charging during boost hours, switching to an EV-specific plan can save you €300–€800 per year compared to a standard tariff.

Use this calculator to compare your current plan against all available EV tariffs and see your exact potential savings.

A home EV charger installation typically costs €800–€1,500 including the unit and electrical work. The SEAI offers a grant of up to €300 toward installation, bringing the net cost down to €200–€900 for most homes.

A 7kW wallbox is the most common choice for Irish homes. Read our complete home charging guide for more details.

Home charging is significantly cheaper. Public rapid chargers typically cost 45–60c/kWh, while home charging on a night rate costs 15–20c/kWh and an EV boost rate can be as low as 5–12c/kWh. That's up to 10× cheaper than public rapid charging.

The cheapest window is during boost hours (typically 02:00–05:00) if your provider offers an EV tariff. The next cheapest is during night rate hours (23:00–08:00). Select a provider above and the interactive timeline will show you exactly when each rate applies.

Most EVs let you schedule charging from the car's infotainment system or app. A 7kW charger can add roughly 35kWh in the 3-hour boost window — enough for most daily driving needs.

Yes. A typical 5kWp solar panel system in Ireland generates around 4,500–5,000 kWh per year. If you charge your EV during daylight hours (weekends, working from home), you can offset a significant portion of your charging costs. Adding a home battery increases self-consumption further.

Use the solar and battery options in the calculator above to see the impact. Irish providers also pay 15–25c/kWh for electricity you export back to the grid.

The calculator uses real tariff data from Irish electricity providers (verified March 2026) and actual EV battery specifications from our database of 205 vehicles. Household usage estimates are based on CRU averages for Irish homes.

For the most accurate results, enter your exact rates from a recent bill, select your specific car model, and adjust charging habits to match your actual routine.
