If you're thinking about switching to an electric vehicle (EV) or already own one, you're probably wondering: how much will it cost to charge at home?

Good news—charging at home is usually much cheaper than filling up a petrol or diesel car. That said, the exact cost depends on a few factors. Let’s break it down.

🧮The Simple Formula

To estimate your charging cost at home, use this formula:

Battery size (kWh) × Electricity price (€/kWh) = Charging cost

For example:
A 60 kWh battery × €0.30 per kWh = €18 for a full charge

→ That’s the cost to charge from 0 to 100% (in theory).

In real life, you likely never charge from 0%, so a full charge often costs a bit less.

⚡What Affects Charging Costs?

Your Energy Tariff

• Fixed, day/night, or dynamic rates can make a big difference.

• Charging at night is often cheaper.

Charging Efficiency

• A bit of energy is always lost as heat—typically ~10%.

Solar Panels

• With solar, you can often charge for free during sunny hours.

• Smart chargers — like Smappee — can automate this to maximize savings.

  • Smart charging - solar only

  • How does smart charging - schedules only work?

🔌 What About Public Charging?

Home charging is usually the cheapest. Public chargers can cost:

• €0.40–€0.70 per kWh at AC chargers

• €0.60–€1.00 per kWh at fast DC chargers
  And often come with additional fees (per session or per minute).

Make sure you always the check the Public Charging (EMSP) map in the Smappee App to properly know the prices before you start charging.
