Home vs public charging in Brazil — the 5 cheapest EVs to charge
Public and DC fast charging in Brazil 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 R$2.28/kWh against R$0.91/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 Brazil:
| Electric model | Per 100 km at home | Public (≈2.5× home) | Extra per year if all-public |
|---|---|---|---|
| BYD Dolphin Mini | R$9.93 | R$24.82 | +R$1,861 |
| BYD Dolphin GS | R$15.41 | R$38.52 | +R$2,889 |
| Renault Kwid E-Tech | R$15.41 | R$38.52 | +R$2,889 |
| BYD Atto 3 (Yuan Plus) | R$16.55 | R$41.36 | +R$3,102 |
| Volvo EX30 Plus Single Motor | R$17.58 | R$43.95 | +R$3,296 |
- BYD Dolphin Mini is the cheapest EV to charge in Brazil — R$9.93 per 100 km at home — and at the public estimate (R$24.82) it still beats the R$42.98 of petrol a 7 L/100 km car burns over the same distance.
- A BYD Dolphin GS draws 14.9 kWh per 100 km, so home charging runs R$15.41; at the public estimate (R$38.52) it still beats the R$42.98 of petrol a 7 L/100 km car burns over the same distance.
- For the Renault Kwid E-Tech, public-only charging would add about R$2,889 a year at 12,500 km/year over charging at home (R$15.41 vs R$38.52 per 100 km); even then it stays under the R$42.98 a 7 L/100 km petrol car needs.
- A BYD Atto 3 (Yuan Plus) draws 16 kWh per 100 km, so home charging runs R$16.55; at the public estimate (R$41.36) it lands about level with the R$42.98 of petrol for a 7 L/100 km car.
- For the Volvo EX30 Plus Single Motor, public-only charging would add about R$3,296 a year at 12,500 km/year over charging at home (R$17.58 vs R$43.95 per 100 km); that puts it level with a 7 L/100 km petrol car's R$42.98.
At the 2.5× public estimate, charging stays cheaper than petrol for 4 of these 5 models — without a home charger, which model you pick decides the verdict in Brazil. 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.
