The charging time of an electric car is easy to calculate. To make this calculation, you need the battery capacity and the charging capacity of the car. If you divide these, you know how long it takes to charge an electric car.
If your car has a capacity of 60 kWh, around 55 kWh of this will be used effectively. If you charge the battery with a 1-phase connection that has a charging capacity of 7 kW. The calculation: 60kWh/7kW = about 8 and half hours charging time.
