To optimise the service life of the high-voltage battery in your BMW electric car, BMW recommends maintaining a state of charge between 10 and 80% in everyday use. Charging an electric vehicle with alternating current (AC) may take longer, depending on the infrastructure available and the capacity of your high-voltage battery. On the other hand, direct current (DC) charging can be significantly quicker. In everyday use, you should prioritise charging at AC charging stations, Wallboxes and DC charging posts with a lower charging power of up to 100 kW. This optimises both the charging efficiency and the service life of the battery in your BMW electric vehicle. Enjoy convenient, rapid and safe charging with a Wallbox, which makes the charging process significantly quicker compared to a domestic power socket. The BMW Wallbox has a charging power of up to 22 kW.⁵
