Charging the vehicle
Vehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your vehicle, e. g., due
to the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and
systems, the applicable laws and regulations
must be observed.
Concept
The vehicle can be charged using various
charging cables at charging stations or house‐
hold sockets. Control and monitoring of the
charging process are handled completely au‐
tomatically. The charge current strength can
be set via iDrive.
General information
High-voltage battery
The high-voltage battery is used as an energy
accumulator. The high-voltage battery can be
charged by energy recovery during the trip or
via the power grid.
In order to operate the high-voltage battery
optimally, charge the vehicle regularly and
completely on a compatible charger.
When charging via the power grid, you can
chose between the following variants.
Level 1 charging via a household socket.
Level 2 charging via a Level 2 charging sta‐
tion.
Level 1 charging is possible via a household
socket with a voltage of 120 volts.
For optimal use of the energy from the power
mains, charging at a charging station, e.g.,
BMW Wallbox, is recommended.
Charge current
General information
The charge current strength is indicated in am‐
peres.
The vehicle cannot automatically detect the
maximum permissible charge current strength
of the power grid during charging via a house‐
hold socket or charging station.
Level 1 charging
Prior to the first Level 1 charging at your own
household socket, as well as when charging at
external electrical power sockets in Level 1,
the allowed charge current strength must be
determined, for instance by a qualified electri‐
cian.
The charge current strength for Level 1 charg‐
ing, refer to page 281, can be adjusted in the
vehicle in three levels.
At delivery, the charge current for
Level 1 charging is set to the lowest level.
Depending on the country-specific version,
one of several ampere ratings is printed on the
enclosed Level 1 charging cable. This ampere
rating is the limit which must be adhered to for
the vehicle if the charge current is set to the
highest level. Depending on the charge cur‐
rent, the change in charge current strength
varies when lower levels are set.
