Home vs public charging in Portugal — the 5 cheapest EVs to charge
Public and DC fast charging in Portugal is billed per session by each network and varies widely, so we model it the way the kernel does on every cost page: 2.5× the home rate — about €0.69/kWh against €0.28/kWh at home. That is a planning estimate, not any network's tariff. Here is what it does to the 5 cheapest-to-charge models we price in Portugal:
| Electric model | Per 100 km at home | Public (≈2.5× home) | Extra per year if all-public |
|---|---|---|---|
| Tesla Model 3 RWD | €4.10 | €10.24 | +€737 |
| Tesla Model Y Standard | €4.13 | €10.32 | +€743 |
| Mercedes-Benz CLA 250+ (EQ Technology) | €4.16 | €10.40 | +€749 |
| Mercedes-Benz CLA 350 4MATIC (EQ Technology) | €4.29 | €10.71 | +€771 |
| Renault 5 E-Tech Five 95 40 kWh | €4.60 | €11.50 | +€828 |
- Tesla Model 3 RWD is the cheapest EV to charge in Portugal — €4.10 per 100 km at home — and at the public estimate (€10.24) it still beats the €13.17 of petrol a 7 L/100 km car burns over the same distance.
- A Tesla Model Y Standard draws 13.1 kWh per 100 km, so home charging runs €4.13; at the public estimate (€10.32) it still beats the €13.17 of petrol a 7 L/100 km car burns over the same distance.
- For the Mercedes-Benz CLA 250+ (EQ Technology), public-only charging would add about €749 a year at 12 000 km/year over charging at home (€4.16 vs €10.40 per 100 km); even then it stays under the €13.17 a 7 L/100 km petrol car needs.
- A Mercedes-Benz CLA 350 4MATIC (EQ Technology) draws 13.6 kWh per 100 km, so home charging runs €4.29; at the public estimate (€10.71) it still beats the €13.17 of petrol a 7 L/100 km car burns over the same distance.
- For the Renault 5 E-Tech Five 95 40 kWh, public-only charging would add about €828 a year at 12 000 km/year over charging at home (€4.60 vs €11.50 per 100 km); even then it stays under the €13.17 a 7 L/100 km petrol car needs.
Even at the 2.5× public estimate, all 5 of these models still undercut the €13.17 of petrol a typical 7 L/100 km car burns per 100 km — in Portugal the charging case survives without a driveway. Our 5-year totals on each model page assume 80% home / 20% public charging at this same multiple — these two columns are the ends of that range.
