One argument against charging e-cars from normal sockets is that Loading timewhich is measured by the low flow rate of 2.3 kW per hour. Depending on the battery capacity of the vehicle, it can be up to 24 hours pull it in (e.g. with a 100 kWh battery). During this time, the can is continuously loaded and emits heat. The following bill This illustrates the charging time: an electric car battery with a capacity of 38 kWh needs more than 15 hours for a full charge with 2.3 kW, whereas with eleven kW it is 3.5 hours. On the fast charger, the battery draws 80 percent of its energy in 40 minutes. However, slow charging is also particularly gentle on the car battery.
