Charge Time = Battery Capacity (Ah) / Charging Current (A) This formula is a straightforward way to estimate charge time. For instance, if you have a battery capacity of 50 Ah and a charger that provides 10A, the battery would theoretically take 5 hours to charge. However, this doesn’t account for inefficiencies in the battery charging process.
Enter the current charge level of your battery as a percentage. Enter the desired charge level you want to achieve as a percentage. Enter the charging power of your charging station in kilowatts (kW). Click on the “Calculate” button to get the estimated charging time.
An empty battery will take longer to charge than a battery already at 50%. Interestingly, the rate at which electricity is accepted declines as the battery gets closer to full. In other words, a depleted battery typically adds more miles in 20 minutes of EV charge time than a half-full battery.
Electric vehicles (EVs) often have batteries with capacities ranging from 40kWh to 100kWh. Using a home charging station that delivers 7kW, a 70kWh battery would theoretically take 10 hours to charge. However, many EVs have fast-charging capabilities at commercial stations, where higher currents can reduce this time significantly.
To use this EV Charging Time Calculator, please follow the instructions below: Enter the total battery capacity of your electric vehicle in kilowatt-hours (kWh). Enter the current charge level of your battery as a percentage. Enter the desired charge level you want to achieve as a percentage.
Based on your battery being a lithium battery and the charge rate being relatively slow, you assume a charge efficiency of 95%. With that, you can plug your values into Formula 2. In this example, your estimated charge time is 8.42 hours. Using Formula 1, we estimated this same setup to have a charge time of 8 hours.
