Calculadora de Carregamento de VE Online Grátis
Calculate EV battery charge time, added range, and cost with various charger levels
The EV Charging Calculator tells you exactly how long it will take to charge your electric vehicle and what it will cost, based on your battery size, current charge level, charger type, and local electricity rate. It's built for EV owners planning overnight home charges, road-trip fast-charge stops, and cost comparisons between charger speeds.

Sobre Esta Calculadora
Electric vehicle ownership comes with a new set of calculations that petrol car owners never had to think about: charging time, electricity cost per mile, and how charger speed affects your schedule. This calculator makes those figures instant and concrete.
Enter your battery capacity, current charge percentage, target charge level, and the power output of your charger (Level 1 is a standard household outlet at ~1.4 kW; Level 2 home chargers run at 7–11 kW; DC fast chargers reach 50–350 kW). The result shows charge time, kWh consumed, cost at your local electricity rate, and estimated range added.
The calculator works for any EV — car, motorcycle, or van — as long as you know the battery capacity in kWh.
A Calculadora de Carregamento de VE diz exatamente quanto tempo levará para carregar seu veículo elétrico.
Exemplo Resolvido
Home charging a Tesla Model 3 (75 kWh) from 20% to 90%
Entradas:
- Battery capacity: 75 kWh
- Starting charge: 20%
- Target charge: 90%
- Charger power: 7.2 kW (Level 2 home)
- Electricity rate: $0.14/kWh
Passo a Passo:
- Energy needed: (90% − 20%) × 75 kWh = 70% × 75 = 52.5 kWh
- Charging time: 52.5 ÷ 7.2 = 7.29 hours ≈ 7 hours 17 minutes
- Charging cost: 52.5 × $0.14 = $7.35
- Added range (assuming 4 mi/kWh): 52.5 × 4 = 210 miles of range added
