The vehicle can be conveniently charged at home at a conventional household 230 volt power socket, and has a "full tank" after less than four hours. The car's charging port is located behind a flap on the front left side panel. All that is needed for charging is the specially designed cable, which can be stored safely and compactly under the luggage compartment floor. A special seal protects the charging port and plug from the elements. LED light rings on the charging port make the charging status visually clear.
Instead of a normal power socket, a BMW i Wallbox can also be mounted as a charging station. It offers increased charging power, significantly shortening charging time. A display in the specifically tailored instrument cluster informs the driver about the high-voltage battery's current level of charge. Depending on various factors, for example the strength of the charge at the power source, devices actively consuming electricity in the car during the charging process and the use of a Wallbox, it takes less than three hours for an empty high-voltage battery to recharge completely. During external charging, the passenger area can be pre-heated or cooled without affecting the charging status of the high-voltage battery.
