Electric vehicle charging costs significantly higher on public networks than at home

Charging an electric vehicle at home is significantly cheaper than using public networks in Portugal. According to calculations by Galp, charging a 35.5 kWh battery at home costs approximately 7.81 euros, based on a rate of 0.22 euros per kWh. This equates to an estimated 2.60 euros per 100 kilometers.

In contrast, the same 35.5 kWh charge at a public station can cost up to 14.36 euros. This higher price is due to several factors, including operator fees (approximately 4.05 euros), network access tariffs, and taxes such as the Special Consumption Tax (IEC) and VAT.

ERSE notes that home charging does not require a specific mobility contract; it is treated as standard household electricity consumption. While using a conventional domestic socket is cheaper, it is slower than using a dedicated wallbox or three-phase charger, which can replenish 100 km of range in as little as 40 minutes.
