Evcharging Time Calculator
Free Evcharging time Calculator for fuel & energy. Enter your stats to get performance metrics and improvement targets.
Formula
Charging Time = (Battery kWh x (Target% - Current%) / 100) / (Charger kW x Efficiency)
The energy needed is the battery capacity multiplied by the difference in state of charge percentages. This is divided by the charging efficiency to account for energy losses. The result is divided by the charger power in kilowatts to get the time in hours. DC fast chargers taper above 80% SOC, requiring separate calculations for energy delivered above and below that threshold.
