Charging the vehicle  
MOBILITY  
Charge current  
NOTICE  
The charging cable connected to the vehicle  
and the charging cable connections may be  
damaged due to mechanical load. There is  
a risk of damage to property. Do not apply  
mechanical loads to the charging cable and  
the charging cable connections. Route the  
charging cable to the vehicle freely and avoid  
stress due to pulling or bending.  
General information  
The charge current strength is indicated in am-  
peres.  
There are differences in the maximum permis-  
sible charging current depending on the local  
power grid.  
Before charging, set a suitable current limit for  
the charging current.  
When charging at charging stations, the per-  
missible charging current is automatically de-  
tected and a current limit is set.  
Charging the high-voltage  
battery  
When charging at a domestic socket outlet, set  
the current limit yourself.  
The high-voltage battery serves as energy  
storage. The high-voltage battery can be  
charged utilizing energy recovery during the  
trip or via the power grid.  
Safety information  
Charge the vehicle at a suitable charging de-  
vice.  
Warning  
If the charge current strength is adjusted  
incorrectly, the power grid of the domestic  
socket outlet can be overloaded and over-  
heat. There is a risk of fire, injury, and  
property damage. Adjust the charge current  
strength to the power grid prior to charging  
on domestic socket outlets. With unknown  
power networks, set on the lowest level.  
Charge the high-voltage battery regularly so  
that it operates optimally.  
When charging via the power grid, you can  
chose between the following variants:  
Domestic socket outlet.  
Industrial socket.  
AC charging station.  
DC charging station.  
Charging on a domestic socket  
outlet  
The permitted charge current strength must  
be determined, for instance by a qualified elec-  
trician, before first charging with your own do-  
mestic socket outlet or when charging with  
third-party domestic socket outlets.  
For optimal use of the energy from the power  
grid, charging at a charging station, e.g., at a  
BMW Wallbox, is recommended.  
The power grid and charging station should  
enable a charging capacity of at least 11 kW.  
A lower charging capacity will extend the  
charging time.  
Ensure that the charging station is installed  
according to the technical requirements of the  
power grid, e.g. by a qualified electrician.
