EV Charging Time Calculator

This EV Charging Time Calculator estimates how long it takes to charge an electric vehicle based on battery size, charging percentage and charger power.

Battery size (kWh) Starting battery percentage (%) Target battery percentage (%) Charger power (kW)

Enter your details above to calculate charging time.

How charging time is calculated

Charging time = Battery size × (Target % − Start %) ÷ 100 ÷ Charger power

Example

Energy added = 60 × (80 − 20) ÷ 100 = 36 kWh

Charging time = 36 ÷ 7 = 5.14 hours

Approximately 5 hours 9 minutes
