General information  
Warning  
Damaged or worn charging equipment, e.g.,  
worn contacts, can become hot. There is a  
risk of fire. Only use chargers that are in good  
condition.  
The vehicle can be charged using various  
charging cables at charging stations, domestic  
socket outlets or industrial sockets.  
Control and monitoring of the charging process  
are handled fully automatically. When charging  
with AC, the charge current level can be ad-  
justed via iDrive.  
Warning  
Even when it is indicated that the high-volt-  
age battery is discharged, the high-voltage  
system is always still under high voltage.  
There is a risk of fire or a risk of injury. Do  
not touch or change live parts, e.g., orange  
high-voltage cables, even when the batteries  
are discharged.  
Safety information  
Warning  
Working with electrical current improperly can  
lead to electric shock due to high voltages or  
high currents. There is a risk of fire or danger  
to life. Observe the general safety regulations  
when working with electrical current.  
Warning  
Contact with live components can lead to an  
electric shock. High voltage is present at the  
charging connection. There is a risk of injury  
or danger to life.  
Warning  
It is recommended that work on the charg-  
ing connection, for example cleaning, is per-  
formed by an authorized service center or an-  
other qualified service center or repair shop.  
A faulty or incorrectly designed charging de-  
vice at the charging location can cause dam-  
age to the vehicle and overload the power  
supply at the charging location. There is a

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. Adjust the charge  
current strength to the power grid prior to  
charging on domestic socket outlets. With un-  
known 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.

General information  
The current limit for charging with the Mode 2  
charging cable and the Mode 3 charging cable  
can be set via iDrive.  
Safety information  
Warning  
When charging at domestic sockets on another  
power grid, the set charging current again  
may need to be checked again. The permitted  
charge current strength must be determined,  
for instance by a qualified electrician, before  
charging with a domestic socket outlet.  
Incompatible charging cables, adapters, or  
unsuitable charging stations can heat up,  
cause damage to the vehicle, or lead to an  
electric shock. There is a risk of injury, dan-  
ger to life, and risk of damage to property.  
Use only charging cables, adapters, or charg-  
ing stations that are recommended for the  
respective vehicle type.  
If the approved charging current strength is un-  
known, set the current limit to the lowest level.

nector is completely inserted in the charging  
socket.  
DC charging cable  
The DC charging cable that is permanently  
installed at the charging station makes is  
possible to charge at DC charging stations.  
Charging is performed with direct current  
at designated DC charging stations. At the  
higher dimensioned electrical connection of a  
DC charging station, the charging time is nor-  
mally substantially shorter compared to a do-  
mestic socket outlet or AC charging station.  
AC charging cable  
Mode 2 charging cable  
Mode 2 charging cables can be used to charge  
the vehicle from grounded domestic socket  
outlets. Charging at domestic socket outlet  
electrical connections is performed with alter-  
nating current.  
While charging at a DC charging station, an in-  
dication in the instrument cluster is displayed.  
When a Mode 2 charging cable is used, the  
efficiency values may differ from those stated  
on the energy label.  
Charge the vehicle only with a DC charging ca-  
ble with a length less than 98 ft/30 m.  
The DC charging cable is also referred to as  
Mode 4 charging cable.  
The Mode 2 charging cable is also referred to  
as standard charging cable.  
Storage  
Flexible Fast Charger, Mode 2  
charging cable  
The Flexible Fast Charger is a special mode 2  
charging cable.  
For the outbound delivery, the charging cable  
is stowed in the luggage compartment, for in-  
stance under the cargo floor panel or in a bag.  
Stow charging cable after use in the same  
place again.  
The interchangeable mains plugs of the Flex-  
ible Fast Charger allow you to charge flexi-  
bly using domestic socket outlets or industrial  
sockets with protective conductors.  
If the charging cable is stowed in a bag, fasten  
the bag at an open lashing eye in the luggage  
compartment.  
Roll up the charging cable loosely and make  
sure that it is not damaged when stowed, e.g.,  
cable becomes bent.  
Mode 3 charging cable  
The Mode 3 charging cable makes it possible  
to quickly recharge at sockets of designated  
AC charging stations using a special connec-  
tor. Charging is performed with alternating cur-  
rent at designated AC charging stations. The  
charging process can be completed faster than  
at domestic socket outlets.  
If required, store the charging cable with the  
connector cover attached in order to keep  
moisture out of the charging cable plug.  
Connecting the charging cable  
Depending on vehicle equipment and national-  
market version, a maximum charge current  
level of 16 A to 32 A is possible.  
General information  
Before connecting, if necessary clean the  
charging cable plug and the area between the  
charging socket flap and charging socket, e.g.,  
remove snow.

Plug & Charge  
Principle  
With Plug & Charge, data from multiple charg-  
ing contracts with different charging providers  
can be saved to the vehicle. At compatible  
charging stations, the vehicle automatically  
sends saved data to the charging station. This  
makes it easier to charge at public charging  
stations that are settled by charging contract.  
Once the charging cable is connected, charg-  
ing can begin immediately.  
Charging process  
Principle  
The charging process can be adapted to con-  
straints such as the cost of electricity, available  
current sources, or a low ambient temperature.  
The vehicle controls the charging process in  
such a way that the charging process is com-  
pleted if possible at the departure time. A de-  
parture time must be set for this purpose.  
General information  
A contract with a charging service provider is  
usually required for public charging stations.  
To log in at the charging station, enter your  
contract information into the charging station,  
e.g., by using a charging card. With Plug &  
Charge, there is no need to manually log in at  
the charging station any more.  
General information  
High or low outside temperatures can cause  
longer charging times.  
When charging the vehicle, a charge target can  
be set, thereby shortening the charging dura-  
tion.  
More information on Plug & Charge is  
provided in the My BMW App or online:  
If the Mode 2 charging cable is exposed to  
high temperatures and direct sunlight, this may  
interrupt the charging process. Charging will  
resume automatically.

If the function is enabled, the icon  
indicates the location-based settings,  
which are automatically saved and en-  
abled.  
Principle  
Various settings can be selected for charging  
at charging stations.  
To simplify recharging at known charging loca-  
tions, some changed settings such as charging  
mode can be saved based on location.

Discharged high-voltage  
battery and vehicle battery  
Before charging, ensure that the settings en-  
abled match the desired charging station,  
e.g., charging mode.  
General information  
When the vehicle leaves a known charging lo-  
cation, the settings are automatically set to  
factory settings.  
In addition to the high-voltage battery, the ve-  
hicle has a 12 volt vehicle battery, which is re-  
quired for operation of the onboard electronics.  
With a discharged vehicle battery, no operation  
of the vehicle is possible.  
Functional requirement  
To use the function, a GPS signal must be re-  
ceived.

Charging the vehicle  
MOBILITY  
Recharge the high-voltage battery as close  
to a planned departure as possible. A time  
frame can be set for charging.  
Service life of high-voltage  
battery  
Charging in the time frame, refer to  
page 323.  
General information  
Reduce the load on the high-voltage bat-  
tery by using an efficient, anticipatory driv-  
ing style.  
The performance of the high-voltage battery,  
and thus the vehicle's range, decreases over  
its service life. The service life of the high-volt-  
age battery can be optimized by how it is used.  
Increasing the range, refer to page 309.  
Avoid direct sunlight at high outside tem-  
peratures.  
Charging instructions  
Charging habits have a significant effect on the  
high-voltage battery's service life:  
Long stationary periods, vehicle  
shutdown  
If planning to leave the vehicle stationary for  
long periods of time, note the following:  
If the vehicle is stationary for long periods  
of time with a battery charge of over 80 %,  
this may negatively affect the battery's usa-  
ble energy, charging time, and charging  
power during quick charging.  
If the vehicle is to be stationary for more  
than 6 months, park the vehicle with a  
battery charge between 50 % and 80 %.  
Check the battery charge every 6 months.  
Quick charging often with a charging power  
greater than 100 kW may negatively affect  
the battery's usable energy, charging time,  
and charging power during quick charging.  
If the vehicle is stationary for less than 6  
months, park the vehicle with a charge level  
between 30% and 50%.  
If the vehicle has been charged several  
times in a row with DC, this system may  
temporarily reduce the charging power to  
protect the high-voltage battery. If reduced,  
the charging capacity is reset after a few  
hours. Quick charging again can extend this  
time.  
Do not park the vehicle for longer than  
14 days if the electric range is depleted.  
Do not leave the charging cable connected.  
Maintenance  
The high-voltage battery is maintenance-free.  
Optimizing the high-voltage  
battery's service life  
Proper use can optimize the high-voltage bat-  
tery's service life:  
End of high-voltage battery service  
life  
If unrestricted driving can no longer be ensured  
because the high-voltage battery is exhibiting  
very advanced aging, Check Control messages  
appear to indicate power and range restric-  
tions.  
Charge high-voltage batteries with a low  
charging capacity at an AC charging station  
or Wallbox.  
For daily use, operate the vehicle with a  
charge level between 10% and 80%. A  
charging target of 80% can be set for this.  
The vehicle must be inspected by an author-  
ized service center or another qualified service  
center or repair shop.  
Charge target, refer to page 323.

If, in this case, no inspection is conducted by  
the authorized service center, it may no longer  
be possible to put the vehicle into operation.  
A system error appears before it be-  
comes impossible to put the vehicle  
into operation.  
It is not necessary to interrupt the current trip,  
which can be ended as planned.  
However, it will no longer be possible to  
continue driving the next time the vehicle is  
started.
