2015 BMW I8 battery

A SUSTAINABLE COMBINATION:
INTELLIGENT ENERGY MANAGEMENT
FOR INSPIRING PERFORMANCE AND
OPTIMUM EFFICIENCY.
BMW has been pursuing its EfficientDynamics strategy for more than
a decade. However, no other vehicle combines driving pleasure and
sustainability like the BMW i8. Equipped with innovative BMW eDrive
technology that intelligently combines an internal combustion engine
with an electric drive system, the BMW i8 offers maximum perfor-
mance and sustainable efficiency.

In an urban environment, the BMW i8 offers a range of up to 37 kilo-
meters when traveling on electric power only. For longer distances,
support is provided by the BMW TwinPower Turbo engine – with an
especially intense boost feature in SPORT mode or maximum efficiency
in ECO PRO mode. A predictive power management system developed
specifically for the BMW i8 ensures optimal settings for the two drive
units at all times.

Additionally, every driver can also help to optimize sustainability when
recharging the car: if renewable energy is used to charge the battery,
CO² emissions are reduced even further. Therefore, BMW i recom-
mends green electricity suppliers to make an even greater contributi-
on to environmental protection.

on the lighting system … ,” the following
words should be read as preceding that
passage: “It is strongly suggested that
you … .”
20. At page 181, under the “Battery replace-
ment” section, the text should be disre-
garded and in lieu thereof the following text
should be read:
Use of recommended vehicle batteries
The manufacturer of your vehicle recom-
mends that you use vehicle batteries that it
has tested and recommends for use in your
vehicle; otherwise the vehicle could be
damaged and systems or functions may not
be fully available.
After a battery replacement, the manufac-
turer of your vehicle recommends that you
have the battery registered on your vehicle
by a service center to ensure that all com-
fort functions are fully available, and that
any “check control” messages of these
comfort functions are no longer displayed.

BMW eDRIVEVehicle 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 car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
BMW eDRIVE Special features of the BMW i
High-voltage system
This BMW i is a hybrid vehicle. In addition to
the combustion engine, the vehicle features a
high-voltage system that consists of an elec‐
tric motor and a high-voltage battery among
other things.
Carbon bodyThe vehicle consists of two different functional
units: the drive module made from aluminum
and the life module made from carbon fiber re‐
inforced plastic (carbon).At a glance1Vehicle battery2Electrical drive unit3High-voltage battery4Fuel filler flap5Combustion engine6Charging port
The concept
The hybrid system makes it possible to opti‐
mize fuel consumption and driving characteris‐
tics.
An electric motor assists the combustion en‐
gine. In certain driving situations, the vehicle
can also be driven using only electric power,
thereby reducing fuel consumption.
In addition to this, the electric motor acts like
an alternator: during braking and coasting, it
converts the vehicle's kinetic energy into elec‐ tricity. The current is stored in the high-voltage
battery and is used to drive the electric motor.
Functions
Acceleration boost: ASSIST and eBOOST
Driving off and accelerating require a lot of en‐
ergy. To reduce fuel consumption during high
acceleration and to optimize acceleration, the
electric motor supports the combustion en‐

gine. For this purpose, the electric motor is
supplied by the high-voltage battery.
Electric driving: ePOWER
Under certain conditions, refer to page 64,
the vehicle is powered only by the electric mo‐
tor.
Variable drive configuration
The electric motor drives the front axle and the
combustion engine the rear axle. Depending
on the operating condition, the vehicle has the
options of front-wheel drive, rear-wheel drive
or bundled for four-wheel drive.
Follow instructions for electric driving eDRIVE, refer to page 64, driving with the combustion
engine DRIVE, refer to page 65, and driving
stability, refer to page 109.
Acoustic pedestrian protection
Depending on the country variant, the system
generates continuous driving noise, refer to
page 65, during electric driving up to approx.
20 mph/30 km/h.
Driving with the combustion engine: POWER
The combustion engine provides the perform‐
ance to move the vehicle. If necessary, the
high-voltage battery is charged at the same
time.
The hybrid system always starts the combus‐
tion engine automatically.
Energy recovery: CHARGE
The high-voltage battery is charged while driv‐
ing through energy recovery.
The electric motor acts as a generator and
converts the kinetic energy of the vehicle into
electric current.
Charging can take place in various situations
while the vehicle is in motion:▷When the vehicle is rolling if the accelera‐
tor pedal is not pressed.▷During vehicle braking.
When exerting gentle pressure on the brakes,
the vehicle is only braked by the electric motor.
When the brake pedal is depressed further, the
brake system is activated additionally. This is
why only part of the brake energy is used to
charge the high-voltage battery when exerting
firm pressure on the brake.
The mark in the instrument cluster is located
within the CHARGE range.
Sensible driving and early speed reduction are
important to make full use of the energy recov‐
ery feature.
Display The eDRIVE displays, refer to page 75, pro‐
vide information about the current state of the
drive and visualize the system's use in a dia‐
gram.
Energy-saving driving To save energy while driving, read the follow‐
ing information:
Before driving eDRIVE allows using the air conditioner even
before driving off. The stationary climate con‐
trol, refer to page 127, provides more range
than full air conditioning while driving.
Parked car ventilation during the charging
process can provide maximum range when
driving off.
During driving
▷General driving tips, refer to page 144, for
increasing the range.▷Use the eDRIVE system efficiently, refer to
page 138, for an optimized driving style.▷ECO PRO mode, refer to page 145, for in‐
creasing the range.Seite 32At a glanceBMW eDRIVE32

ment, arrow 1.3.Remove the cover of the battery compart‐
ment, arrow 2.4.Insert a battery of the same type with the
positive side facing up.5.Press the cover closed.
Take the used battery to a recycling
center or to your service center.
New remote controls New remote controls are available from the
service center.
Loss of the remote controls Lost remote controls can be disabled by your
service center.
Emergency detection of remote
control
Also in the following situations, radio-ready
state and drive readiness can be established:
▷Interference of radio transmission to re‐
mote control by external sources e.g., by
radio masts.▷Empty battery in remote control.▷Interference from radio transmissions
through mobile devices in close proximity
to remote control.▷Interference of radio transmission by
charger while charging items such as mo‐
bile devices in the vehicle.
A Check Control message is displayed if one
attempts to turn on the radio-ready state or ac‐
tivate engine readiness.
Activation of drive readiness via
emergency detection of the remote
control
If a respective Check Control message ap‐
pears, hold the remote control with its back
against the marked area on the steering col‐
umn. The BMW logo on the remote control
should be at the same height as the marked
area. Press the Start/Stop button within
10 seconds while pressing the brake pedal.
If the remote control is not recognized: slightly
change the height position of the remote con‐
trol and repeat the procedure.
Personal Profile
The concept Personal Profile provides three profiles, using
which personal vehicle settings can be stored.
Every remote control has one of these profiles
assigned.
If the vehicle is unlocked using a remote con‐
trol, the assigned personal profile will be acti‐
vated. All settings stored in the profile are au‐
tomatically applied.
If several drivers use their own remote control,
the vehicle will adjust the personal settings
