Some prices and indicative examples

To give you an idea without going crazy with numbers, here are some real (approximate) examples:

• A city car with a small battery (such as Dacia Spring EV) can have about 27 kWh.
• A compact car like the Peugeot e-208 or Fiat 500e is around 40 kWh.
• An SUV like Kia EV6 or Tesla Model Y can be at 60 to 77 kWh.
• And cars with very large batteries (such as some Tesla Model S) can reach 100 kWh or more.

And about the charging points:

• Normal plug (domestic): 2.3 kW → slow, enough to leave it overnight.
• Home wall charger (wallbox): 7.4 kW → quite well.
• Fast Public Point: 22 kW or more → ideal for charging while you shop.
• Ultra-fast charging: 50, 100 or up to 350 kW → for long trips, but not all cars accept it.

And about the price of electricity,

• At home (with normal or night tariff): it is usually between €0.20 and €0.30/kWh
  → The most economical, especially if you charge at night.
• At "normal" public points: it can range from €0.40 to €0.60/kWh
  → Good for occasional recharging, but more expensive than at home.
• On ultra-fast chargers: can exceed €0.80/kWh or more
  → Fast for emergencies or travel, but the most expensive per km.

More useful info to understand the results

• Battery capacity (kWh): It's like a car's tank, but electric. The more kWh, the more range. You don't need to know the exact number: if you know if it's a small, medium or large car, you can get an idea.
• Charger power (kW): This is the "speed" at which you put energy into the car. The more power, the faster it charges. But be careful, not all cars accept high power.
• Price per kWh: This is what you pay for each "litre of electricity". If you charge at home, it will probably be cheaper than at a public point.

How is consumption measured in an electric car?

In petrol cars we look at the litres per 100 kilometres (l/100 km). In electric cars, consumption is measured the same, but in kilowatt-hours per 100 kilometres (kWh/100 km). In other words, how much electricity the car needs to travel 100 km. For example, if an electric car consumes 15 kWh/100 km, it is as if it used 15 "litres of electricity" to travel that distance. The most efficient cars are usually between 12 and 16 kWh/100 km, while the largest or heaviest can go over 20 or even 25 kWh/100 km, especially if you are driving fast or in the cold.
