High-voltage battery
The high-voltage battery serves as energy stor‐
age. The high-voltage battery can be charged by
energy recuperation during a journey or from the
mains.
For optimum operation of the high-voltage bat‐
tery, charge the vehicle regularly at a suitable
charging point.
The following different options are available for
charging from the mains:
▷ Domestic socket outlet.
▷ Industrial socket.
▷ AC charging station.
▷ DC charging station.
For optimum use of energy from the grid, charg‐
ing at a charging station, for example BMW Wall‐
box, is recommended.
The BMW Wallbox must meet the following
technical requirements:
▷ Three-phase charging power of at least
11 kW.
▷ Charge current intensity of 16 A.
Charge current
General
Charge current intensity is specified in amps.
The vehicle cannot automatically detect the max‐
imum permitted charge current intensity of the
grid when charging at a domestic socket outlet.
Safety note
WARNING
If the charge current intensity is set incorrectly,
the power supply of the domestic socket outlet
can be overloaded and overheat. There is a risk
of fire. Before charging at domestic socket out‐
lets, adapt the charge current intensity to the
power supply. Set to the lowest level if the
power supply is unknown.
Charging at a domestic socket outlet
Before charging for the first time at your own do‐
mestic socket outlet, and when charging at other
domestic socket outlets, first find out the permit‐
ted charge current intensity, for example by con‐
sulting a qualified electrician.
Current limitation
General
The current limitation for charging with the
Mode 2 charging cable and the Mode 3 charging
cable can be set via iDrive.
Depending on the electrical mains, the set charg‐
ing current strength may have to be rechecked.
Determination of the approved charging current
strength before using a domestic socket outlet
for charging, for example by a qualified electri‐
cian.
If the approved charging current strength is un‐
known, set the current limitation to the lowest
level.
