Charging the vehicle
MOBILITY
Charging the vehicle
Level 1 charging is possible via a household
socket with a voltage of 120 volts.
Vehicle features and options
For optimal use of the energy from the power
grid, charging at a Level 2 charging station, such
as BMW i Wallbox, is recommended.
This chapter describes all standard, country-spe‐
cific and optional features offered with the series.
It also describes features that are not necessarily
available in your vehicle, for instance, 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 ob‐
served.
Charge current
General information
The charge current strength is indicated in am‐
peres.
The vehicle cannot automatically detect the max‐
imum permissible charge current strength of the
power grid during charging via a household
socket or charging station.
Concept
The vehicle can be charged using various charg‐
ing cables at charging stations or household
sockets. Control and monitoring of the charging
process are handled completely automatically.
The charge current strength can be set via
iDrive.
Level 1 charging
Prior to the first Level 1 charging at your own
household socket, or at other household sock‐
ets, the permitted charge current strength must
be determined by a qualified electrician, for ex‐
ample.
General information
The charge current strength for Level 1 charg‐
ing, refer to page 198, can be adjusted in the ve‐
hicle in three levels.
High-voltage battery
At delivery, the charge current for Level 1 charg‐
ing is set to the lowest level.
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.
Depending on the country-specific version, one
of several ampere ratings is printed on the
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. De‐
pending on the charging cable, the charge cur‐
rent strength may vary when lower levels are set.
In order to operate the high-voltage battery opti‐
mally, charge the vehicle regularly and fully using
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.
