Installing a home charging point for an electric vehicle usually costs between 900 and 2,000 euros for a standard setup, though communal garages and long cable runs can push that figure closer to 3,000. The final price depends heavily on the distance between the electrical panel and the charging spot, the length and thickness of the wiring, and whether the installer has to cut through walls or perform additional construction work. While the equipment itself is a cost factor, the labor and civil work often make up the bulk of the budget.

Most homes use alternating current for charging. A standard monofásic installation typically delivers 7.4 kilowatts, which is roughly 32 amps at 230 volts. To reach 11 or 22 kilowatts, a three-phase system is required, usually involving 16 amps or 32 amps per phase, respectively. The actual speed of charging depends on the weakest link in the chain, which is the vehicle’s onboard charger. If a car like the Kia EV3 or the BYD ATTO 2 only supports 11 kilowatts, connecting it to a 22 kilowatt point won’t make it charge any faster. Similarly, the Dacia Spring is limited to 7 kilowatts regardless of the outlet size.
Drivers often feel pressured to install the highest possible power rating to save time, but for overnight charging, a lower power level is frequently sufficient. For example, recovering 40 kilowatt-hours takes just over five hours at 7.4 kilowatts and slightly less than four hours at 11 kilowatts. Even accounting for energy losses and real-world variability, this difference usually fits within a standard overnight sleep cycle. Unless you drive extensively during the day and rely on a quick top-up, upgrading to a 22 kilowatt system for a single vehicle might not offer a practical return on investment.

Homeowners do not always need to increase their contracted electrical power to install a charger. A smart management system monitors real-time consumption and adapts the charging power to ensure the home does not exceed its limit. This dynamic load balancing allows the vehicle to charge even when the rest of the house is using electricity.
