EV Charging Time Calculator.

A typical Level 2 charger (7.6 kW) takes 6-8 hours to charge a 75 kWh battery from 20% to 80%. Use the calculator for your specific vehicle and charger.

Level 2 charging (7.6 kW) adds ~25-30 miles of range per hour. A full charge takes 4-10 hours depending on battery size and charger power.

DC fast chargers (50-350 kW) can charge 20-80% in 20-60 minutes. A 150 kW charger adds ~200 miles in 30 minutes.

On a 7.6 kW Level 2 charger, 8 hours adds ~60 kWh — enough to fully charge most EVs. Level 1 adds only ~11 kWh overnight.

Model 3 (75 kWh): ~8 hours on Level 2, ~25 min 20-80% on Supercharger. Use the calculator with your Tesla's battery size for precise times.

Charger power, battery size, current charge level, temperature, and BMS all affect speed. Charging slows above 80% to protect the battery.

Yes: Time = (Battery kWh × Charge % Needed) ÷ Charger kW. The calculator does this instantly — just enter your numbers above.

kWh needed = Battery × (Target% - Current%) ÷ 100. For 75 kWh from 20% to 80%, you need 45 kWh. Shown in the calculator.

Yes — the last 20% (80-100%) can take as long as the first 80%, especially on DC fast chargers. This protects battery health.
