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.
