Home vs Public Charging Costs
Annual Savings: EV vs Gas

Recarga no Brasil

Em casa (R$0,70/kWh bandeira verde): R$0,10-0,15/km. Posto público AC: R$0,15-0,25/km. Posto rápido DC: R$0,25-0,40/km. Comparação com gasolina a 12 km/L e R$5,80: R$0,48/km. O carro elétrico custa 3-4× menos por km que gasolina em casa. Recarregue durante a madrugada (tarifa branca) para economizar ainda mais.

Instalação em Casa

Wallbox 7 kW: R$3.000-8.000 instalado. Uma tomada industrial 220V (R$200-500) é alternativa econômica para uso moderado. A rede de carregadores no Brasil está crescendo rapidamente — Tupinambá, Zletric e WEG são as principais redes.

⚡ CalcWolf Insight

Installing a Level 2 home charger costs $500-2,000 (equipment + installation) and qualifies for a 30% federal tax credit (up to $1,000). It charges 25-30 miles of range per hour vs 3-5 miles on a standard wall outlet. Most EV owners consider it the single best EV-related investment.
