Charging Time Calculator

Estimate how long it takes to charge your EV based on battery size, charger power, and current charge level

Battery Capacity (kWh)

Charger Power (kW)

Current Charge (%)

20%

Target Charge (%)

80%

Charging Efficiency (%)

Typical: 85-95% (charging losses)

Charging Time

4h 33m

(273 minutes total)

Energy needed: 45.0 kWh

Note: DC fast charging typically slows down significantly above 80% to protect battery health. This calculator assumes constant charging speed for simplicity.

For best battery longevity, avoid frequent charging to 100% and letting the battery drop below 20%.
