EnglishCharging the vehicle -> Service life of high-voltage battery for your BMW i5 2023-2025
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 325.
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 311.
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 325.

MOBILITY
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.
