How Do You Calculate the EV Charging Time? - The Formula

Do you want to do the calculation manually? No problem.

Here is the formula (for AC charging) to calculate the charging time of your EV:

Charging Time of Your Electric Car =

battery capacity / charging power of the electric car

Let’s assume you have a car with a 66.5 kWh battery capacity and a three-phase on-board charger that has a max power transfer capacity of 22 kW.

If you charge it with our go-e Charger Gemini flex 22 kW, the battery will go from zero to full in about 3 hours. It is important to remember that the fuller the battery, the slower it charges. Once the battery is 85-90% charged, the charging process becomes extremely slow. Given this, it makes sense to add about 30 minutes to the amount of time you get after using the above formula.

66.5 kWh / 22 kW ≈ 3 h (+ ~ 30 min)
