(from BMW Press
Release) The next step towards emission-free mobility:
The BMW ActiveE.
With the world premiere
of the BMW Concept ActiveE at the beginning of 2010, just a year
after presenting the MINI E, the BMW Group underscored the rapid and
consistent continuation of its intensive research and development
activities in the field of electric mobility. This concept has now
become perceptible and tangible reality in the form of the BMW
ActiveE.
project i - research and
development of tomorrow’s mobility.
The BMW ActiveE is the
BMW Group’s next systematic step towards an emission-free,
mass-produced electric vehicle. Within the framework of project i,
the BMW Group is carrying out research and development work on the
realisation of electrically powered vehicles. The main focus is on
the concept of a Megacity Vehicle (MCV) that meets the demands of a
sustainable mobility solution for congested urban areas. For this
purpose, the BMW Group is conducting field tests on an
internationally unparalleled scale for the use of purely
electrically driven vehicles in everyday road traffic.
Ongoing field tests in
the USA and Europe involving more than 600 MINI E cars are already
providing vital knowledge about the demands on future electrically
powered production vehicles. Starting in 2011 in the USA, Europe and
China, a test fleet of over 1000 BMW ActiveE vehicles, produced at
the Leipzig plant, will provide further valuable insights into the
everyday use of the vehicle. The findings will serve to deepen the
knowledge already gained on the everyday use of electric vehicles
and to learn more about customer requirements. The feedback from
customers testing the MINI E and the
BMW ActiveE will be fed directly into series production of the MCV,
which the BMW Group will be launching under a new sub-brand in 2013.
With the BMW ActiveE,
the BMW Group is extending field tests on electric mobility with a
clear perspective of series-production capability and is
intensifying research into electric mobility in everyday road
traffic. For this reason, the drive components and energy storage
units that will be used in the MCV are being tested on the BMW
ActiveE at a pre-production stage. The knowledge gained will be fed
directly into series development of the MCV. With the BMW ActiveE,
the future of individual mobility combining driving pleasure with
CO2-free driving is one step closer.
Electric mobility as a supporting
pillar of the EfficientDynamics development strategy.
In the development of
groundbreaking vehicle concepts and drive technologies within the
framework of the EfficientDynamics strategy, the BMW Group attaches
key importance to electric mobility. With EfficientDynamics the BMW
Group has for some time now been very successful in reducing fuel
consumption and emission levels through new and highly-efficient
engine generations, enhancement of aerodynamics, the use of
innovative lightweight construction and intelligent engine
management - and with better performance into the bargain. For
instance, CO2 emissions of the entire vehicle fleet were reduced by
around one third in the years 1995 to 2009. Thanks to
EfficientDynamics, the company is now able to realise additional
economy advantages through the further electrification of the drive
train and hybridisation. In the medium term, the BMW Group is
developing vehicle concepts for emission-free mobility in larger
urban areas. In the long term, EfficientDynamics means the
transition to emission-free mobility - using both battery power and
regeneratively produced hydrogen.
On the way to
sustainable, CO2-free mobility, the BMW Group now presents the next
major milestone - the BMW ActiveE. Following the MINI E, the BMW
ActiveE is the BMW Group’s second electric prototype. With a power
output of 125 kW/170 bhp and maximum torque of 250 Nm, the car
accelerates from 0 to 100 km/h in 9 seconds, demonstrating the
dynamic and agile characteristics of a BMW, and as is typical of
electric vehicles, straight from a standstill. At the same time,
newly conceived lithium-ion energy storage units facilitate a
vehicle range of around 160 kilometres (100 miles) in everyday
operation.
Just like the MINI E,
the BMW ActiveE is a conversion car, an electric vehicle based on
the body shell of a vehicle with a combustion engine. The BMW
ActiveE integrates all electric drive components such as energy
storage unit, electric motor and power electronics in a vehicle body
that was not originally intended for this purpose - and without
compromising on space or comfort in the interior. Therefore, the BMW
ActiveE is the BMW Group’s first electric vehicle to offer four
fully-fledged seats and a 200-litre luggage compartment. This
achievement by BMW developers is even more impressive in terms of
the vehicle’s role during the initial testing phase. The BMW ActiveE
incorporates a pilot series version of the drive train and energy
storage unit from the MCV with a partly identical, partly similar
geometry in a vehicle from a different concept so that these
components may undergo preliminary testing. However, except for a
small scoop in the bonnet and a smaller boot, the exterior and the
interior design is virtually the same as that of the series
production vehicle.
Intelligent utilisation of
construction space to ensure optimal functionality.
The BMW ActiveE is
equipped with three large energy storage units that are positioned
in the area where the engine block, power transmission to the rear
wheels and the tank are to be found in a vehicle with a combustion
engine. The drive train of the BMW ActiveE - i.e. the electric motor
with gear and power electronics - directly on the rear axle in order
to save space. Thanks to this measure, the BMW ActiveE corresponds
to a conventional
BMW 1 Series Coupe with
regard to available interior space. Driver and front-seat passenger
as well as passengers at the rear have the same amount of space at
their disposal as in the BMW 1 Series Coupe and do not have to
suffer any disadvantages at all with regard to headroom, legroom or
shoulder room. This is due to the ideal positioning of the power
electronics, which are located for functional reasons above the
rear-axle mounted electric motor. With a volume of 200 litres, the
boot offers sufficient space for bottle crates or two 46-inch golf
bags.
Crash safety has top priority.
Within the framework of
the conversion of the BMW 1 Series Coupe into the BMW ActiveE, 350
newly developed body components, which are invisible to the
observer, ensure that the car fulfils the same high standards with
regard to crash safety, construction space and comfort as the
original vehicle with a combustion engine. One of the major
challenges in this respect was the intelligent integration of the
energy storage units and drive components into the space made
available due to the omission of combustion engine components. At
the same time, it was necessary to ensure that the three large
energy storage units located at the front end as well as the tunnel
and tank could not be damaged or destroyed.
The front end: crash structure and
energy storage units instead of a combustion engine.
In order to achieve the
best possible range, the BMW ActiveE is the first limited production
electric vehicle in which part of the high voltage storage units is
integrated into the front end of the vehicle at the cowl. There, one
of the three energy storage units of the BMW ActiveE takes up around
half of the construction space normally occupied by the combustion
engine. Extensive measures implemented in this area guarantee
optimal passenger safety in the event of a crash and also ensure
that the high-voltage storage unit, ancillary components and battery
fluid containers remain undamaged. Hence the BMW ActiveE meets the
same high safety standards as a BMW 1 Series with combustion engine,
fulfilling not only crash safety requirements stipulated by the
government, but also the stringent BMW corporate demands on passive
safety, some of which are even higher than those required by law.
Construction space measures and
weight optimisation.
In addition to passenger
crash safety, BMW Group engineers focused in particular on the
integration of the required battery capacity without having to
compromise on interior space. Many of the well-thought-out solutions
are to be found in the details. For example, a modified tunnel
housing in the undercarriage facilitates a larger tunnel volume
without reducing the amount of space available to passengers. In
another area, a slightly modified centre console angle provides more
construction space resulting in increased battery capacity.
Moreover, in order to
increase the car’s range even further, it was necessary to keep the
overall weight of the vehicle down to a minimum. The conversion
concept sets certain limits for weight optimisation as the concept
necessitates the incorporation of more parts, nevertheless the
engineers working on the BMW ActiveE have managed to achieve the
best possible reduction in weight. Throughout the entire development
process, all new components were constantly optimised with regard to
function and weight. Consequently, the BMW ActiveE offers the best
possible solution in terms of weight reduction within the framework
of a conversion concept. However, weight-optimised electric mobility
can only be demonstrated in the form of a purpose-built car such as
the MCV, as it is ideally adapted to the conditions and requirements
of electric mobility.
The design: clearly a BMW, clearly
a very special concept.
The BMW ActiveE is based
on the BMW compact-class model known for its outstanding agility and
efficiency - the BMW 1 Series Coupe. With its powerful-looking
proportions, the BMW ActiveE stands for compact agility, the
convex-concave design vocabulary giving the vehicle an even more
dynamic appearance. However, specific visual interior and exterior
accents give indication of the exceptional character of the purely
electrically powered BMW. Silver coloured, circuit-inspired graphic
elements on an Electric Blue background run over the entire Alpine
White car body. The intentional asymmetry of the graphic elements
gives the vehicle a uniquely distinctive and agile appearance, the
blue shadowing providing additional depth.
Furthermore, the flowing
design of the scoop in the bonnet differentiates the exterior design
of the BMW ActiveE from a conventional BMW 1 Series Coupe. It
provides space for the energy storage unit located beneath it. The
completely closed rear apron is a distinctive feature of the BMW
ActiveE. As the ActiveE does not have a combustion engine, there is
no need for tailpipes and an exhaust system. Where the tailpipes are
normally located, the BMW ActiveE boasts a silver-blue accentuating
trim in the completely closed rear apron that indicates that the
vehicle is free of emissions. Further differentiating features are
the logo “ActiveE” on the back of the car and the “eDrive” logos on
the side panels as well as the high-quality chrome kidney grille.
In order to increase the
vehicle’s range even further, the BMW ActiveE rides on wheels of the
latest generation of tyres with optimised rolling resistance. This
results in a rolling resistance that is up to twenty percent lower
compared to previous series production tyres. The wheels of the BMW
ActiveE are complemented with by far the lightest 16-inch alloys by
BMW and boast a double V-spoke design. A more sporty 17-inch aero
wheel rim with a five-spoke design is also available.
In the interior the
features of a BMW 1 Series Coupe are also combined with individual
details that emphasise the unique BMW ActiveE concept. Blue
contrasting seams accentuate the Dakota Leather seats in exclusive
Pearl Grey. Dashboard and door linings are fitted with interior trim
in Alpine White, which is available for the first time, and sport a
high-quality “ActiveE” appliqué that transfers the exterior graphics
into the interior of the car. The shift lever plaque in black and
blue complements the overall graphic concept.
BMW eDrive - the BMW ActiveE’s
control display concept.
The instrument cluster
und the control system iDrive were adapted to the electric drive
concept of the BMW ActiveE and enhanced by specific display
functions. Instead of indicating the engine speed, the instrument on
the right of the cluster shows the amount of energy being taken from
the battery or the current amount being supplied to it through
recuperation. When the vehicle is at a standstill, the middle
position of the needle indicates that the vehicle is ready to drive,
as the BMW ActiveE has no engine sound to inform the driver whether
or not the engine is ready to be started. If the vehicle is not
ready to drive, the needle rests at the bottom left of the
instrument. The “fuel gauge” below it indicates the battery charge
level. Furthermore, the onboard computer provides additional vital
information such as the remaining vehicle range, for example.
The eDrive display
functions on the Central Information Display depict vehicle energy
flows to make electric mobility even more perceptible and
comprehensible. During the journey an active schematic
representation of the vehicle informs the driver whether energy is
currently being taken from the battery or being fed in to it via
recuperation. Moreover, the driver can see the current charge state
of the battery and also check whether the air conditioning or the
heating system is working. This representation can, if required,
also be shown as a spilt screen to allow the simultaneous display of
additional infotainment contents or the route guidance of the
navigation system. When the vehicle is at a standstill, it is also
possible to see on the display whether the vehicle is currently
being charged or whether the battery and interior are being
conditioned. In addition, a special battery information menu
provides information on the battery energy level as well as the
current and remaining vehicle range. During charging it also
indicates the remaining charging time.
Optimum comfort, optimum
efficiency - the ECO PRO Mode.
If the driver wishes to
increase the range of the BMW ActiveE even further, it is now
possible to do this via the ECO PRO Mode. As soon as the driver
activates the switch on the centre console, the vehicle’s drive
configuration and comfort functions are modified to facilitate an
even more efficient driving style. Due to an adapted accelerator
pedal characteristic, less power is demanded in the ECO PRO Mode
than in the normal driving mode, but with the same pedal travel.
Also, the heating and cooling characteristics of the heating and air
conditioning systems have a flatter setting and therefore use less
energy. The driver is also provided with tips on how to reduce
energy consumption even further for the best possible motoring
efficiency.
Emission-free, powerful and
compact: the drive system of theBMW ActiveE.
The BMW ActiveE
represents typical BMW driving pleasure in a new, emission-free
form. The heart of the BMW ActiveE is the powerful electric
synchronous motor, the components of which were designed with the
requirements of the MCV in mind and which are now being tested in a
pilot production series. Maximum power output of the electric drive
system is 125 kW/170 bhp. Maximum torque of 250 Nm is - as is
typical of electric vehicles - available from a standstill and, for
the first time, remains utilisable across an exceptionally broad
load range. As a result, the BMW ActiveE accelerates from 0 to 100
km/h in just 9 seconds, the 60 km mark being reached in less than
4.5 seconds. Top speed is electronically limited at around 145 km/h
(90 mph).
The permanent-magnet
hybrid synchronous motor and the power electronics of the BMW
ActiveE were developed entirely in-house and are characterised in
this combination by exceptional efficiency, optimised power
development and a compact design. The innovative character of the
electric drive system is reflected above all in the relation between
engine output and space requirement. The entire power pack including
power electronics and transmission with differential is integrated
into the modified rear-axle support of the BMW ActiveE, and with a
125 kW output, still has a total weight that falls below 100
kilograms.
Drive and slow down with the
accelerator pedal.
Not only does the
spontaneous response enhance the intensive driving experience in the
BMW ActiveE, but also the possibility to slow down using the
accelerator pedal. When the driver takes his or her foot off the
pedal, the electric motor assumes the function of a generator that
feeds the electricity gained from kinetic energy back into the
vehicle battery. At the same time, braking torque is created, which
effectively slows the vehicle down. In this way, the accelerator
pedal becomes a “drive pedal”. In urban traffic around 75 percent of
all deceleration processes can be performed without using the brake
pedal. Intensive use of this so-called recuperation of energy via
the motor also results in a range increase of up to 20 percent. Only
when the driver wishes to slow the vehicle down faster by stepping
on the brake pedal does the conventional braking system of the BMW
ActiveE additionally intervene.
Gliding - “coasting” along the
road.
Unlike the MINI E, the
BMW ActiveE features a distinctive “intermediate position” of the
accelerator pedal, allowing the vehicle to “glide”. As a result, the
vehicle does not immediately recuperate when the driver decelerates,
but “de-clutches” using the electric motor’s zero momentum control,
thereby utilising its own kinetic energy to move forward. The BMW
ActiveE then “glides” along the road without using energy. In
addition to foresighted driving, gliding offers a most convenient
way of increasing the vehicle’s range. A further result of the
modification of the accelerator pedal characteristic curve is a
significantly more precise pedal response and there are virtually no
noticeable load changes.
Intelligent vehicle dynamics
through Stability Management for Regeneration.
When the driver releases
the accelerator pedal in order to slow down, the recuperative brake
torque only has an effect on the rear wheels. For this reason the
BMW ActiveE features an adapted drive-active vehicle dynamics
interface, “Stability Management for Regeneration”, in order to also
ensure adequate vehicle stability during recuperation. The familiar
traction control system ASC and Dynamic Stability Control (DSC) have
been adapted to the specific characteristics of the electric drive
train. Based on various parameters, Stability Management for
Regeneration adapts the recuperation level to each driving
situation, combining the highest level of recuperation with best
possible vehicle stability when decelerating in any situation.
Should a situation arise that is critical for vehicle stability when
using recuperative or hydraulic brakes, the optimised DSC function
ensures constant vehicle stability by means of targeted intervention
into the braking system and engine management. Furthermore, the ASC
system ensures that the rear wheels are able to transfer the high
torque of the electric drive into maximum propulsion when starting
off.
Well-adjusted: the lithium-ion
storage unit with its own liquid cooling system.
Specially developed
lithium-ion storage cells ensure the energy supply of the drive
system and all further functions of the BMW ActiveE. These
high-voltage battery units excel above all through their high
storage capacity. The BMW ActiveE features storage cells, which are
being used for the first time and were jointly developed by the BMW
Group and its associate partner SB LiMotive exclusively for
automotive use. The technological competence of the cooperation
partner SB LiMotive ensures that the high storage capacity and cycle
stability of the lithium-ion batteries are also guaranteed under the
exceptional conditions of automotive use and the associated demands
with regard to lifespan, operational stability and safety.
With the BMW ActiveE
developers are testing the storage cells and the storage
electronics, which are to be installed later in the MCV. Combined
into modules of six, eight or ten storage cells, they fit literally
perfectly into the available construction space in the BMW ActiveE.
Construction space, which is reserved in vehicles featuring a
combustion engine for components the electrically powered BMW 1
Series Coupe does not require, is intelligently utilised. The large
battery unit of the BMW ActiveE takes up the space in the lower area
of the vehicle normally intended for the conventional drive train.
In order to accommodate additional storage cells, the space at the
rear that has become available through the omission of a fuel tank
is utilised. Further lithium-ion cells are located at the front end
in front of the cowl.
The BMW ActiveE’s three
large storage modules are each protected by a specially constructed
steel-plate battery housing with integrated liquid cooling system.
The cooling system constantly maintains the ideal operating
temperature of the energy storage units, thereby significantly
contributing towards an increase in the service capability and
lifespan of the battery cells. The air conditioning/heating system
tempers the liquid running through the storage unit housing via a
heat exchanger. If necessary, the liquid can also be heated in order
to bring the energy storage units up to the ideal temperature of
approximately 20° Celsius even during the winter.
Thanks to these
measures, the BMW ActiveE achieves a range of around 160 kilometres
(100 miles) with a full battery charge and auxiliary consumers
switched on. According to the American consumption cycle FTP72, the
vehicle has a range of up to 240 kilometres (150 miles). Intelligent
battery management especially developed for the BMW ActiveE ensures
that this range can be achieved as far as possible independently of
external climatic conditions.
Fast and flexible retrieval of
fresh energy.
The consistent
development of electrically driven series production vehicles also
encompasses innovative solutions for flexible, convenient and
user-friendly charging of the vehicle’s energy storage systems. The
lithium-ion battery units featured in the BMW ActiveE can be
supplied with fresh energy from the most diverse external power
sources. The vehicle is not dependent on a specific battery charging
terminal and, depending on availability, electricity of varying
current strength can be fed into the storage unit. The respective
transformation is guaranteed by the integrated, highly efficient
comfort battery charger. As a result the driver has a significantly
higher degree of flexibility.
In addition to using the
so-called wallbox, a 32-ampere power supply terminal, installed at
the user’s home and optimised to obtain the shortest possible
charging times, the driver can also connect the vehicle to a
conventional power socket or a publicly accessible charging station.
The standardised
US plug SAE1772 on the vehicle constantly ensures unvarying access
to the charging point and special battery charger leads with
corresponding standardised adapters ensure trouble-free connection
in every country in which the system is available.
The energy storage units
can be fully charged within four to five hours using the wallbox at
32 amperes. A range of around 40 kilometres is possible after just a
one-hour charge at the wallbox. Using a conventional socket in
Europe, the energy storage unit is fully charged over night.
The power electronics - greater
efficiency, enhanced development of power.
The BMW ActiveE’s power
electronics developed by BMW regulate the required strength and
voltage of the supply of electricity to the electric motor. They
ensure full utilisation of the drive system’s full dynamic
potential. Only the correct power supply to the aggregate will
release the high output and guarantee homogeneous development of
power. As in the future MCV, the BMW ActiveE’s power electronics are
located above the rear axle on the electric motor, forming a
complete unit together with the aggregate.
Apart from controlling
the electric motor, the power electronics also ensure the power
supply to the onboard electrical systems. With the aid of a voltage
transformer and incorporating intelligent battery management, they
ensure the reliable supply of electricity to all vehicle functions
including the comfort and infotainment features. Central control
functions, which are integrated into both the power electronics as
well as the energy storage system, permanently monitor all
components. The driver is immediately informed of any possible
malfunctions, in the event of which the system is automatically
secured and switched off if necessary.
Everything from a single source -
BMW Group drive technology competence.
The performance of the
drive system in the BMW ActiveE is typical of a BMW. The exceptional
dynamics, agility and efficiency are the result of intensive
development efforts. With the exception of the storage cell, BMW
Group engineers develop everything that constitutes an electric
vehicle – the energy storage module and its wiring, the electric
motor, the power electronics and the transmission. After all, the
BMW Group wishes to continue upholding its claim to producing the
world’s best drive systems - drive systems that stand out from the
competition through efficiency, performance and running smoothness,
even when electric power and not fuel is being transformed into
movement. The harmonious interaction between drive train and power
electronics, road performance and range demonstrate the BMW Group’s
high degree of competence in this field.
Superior and comfortable - typical
BMW, even with regard to handling.
On the road, the BMW
ActiveE offers the typical BMW driving experience. Weighing a total
of approximately 1,800 kilograms, the coherent overall concept
comprising drive train, handling characteristics and package
guarantee the familiar supreme and agile road performance of a
BMW 1 Series Coupe. The positioning of the energy storage units
results in a beneficial lowering of the vehicle’s centre of gravity.
Moreover, the flexible distribution of the storage units facilitates
the well-balanced 50:50 axle load distribution so typical of BMW
automobiles. Thanks to the dynamic wheel load shift, more weight
bears down on the drive wheels, facilitating enhanced traction and
power transfer of the high torque.
In addition to the
adaptation of the rear axle to accommodate the electric drive, the
BMW ActiveE’s suspension-related modifications are mainly restricted
to components. For example, steering characteristics, springs and
dampers are adapted to the higher weight in comparison to the series
production version in order to reproduce typical BMW 1 Series
handling in combination with the electric drive train. The
suspension setting was chosen with a special focus on comfortable
and superior driving in cities and the urban environment for which
the BMW ActiveE is predominantly designed.
BMW ConnectedDrive remote
functions for the BMW ActiveE.
With BMW MyRemote, BMW
enables the user to access the extensive range of BMW ConnectedDrive
functions via an app for the Apple iPhone (from 3G) and the iPad.
The user has at his or her disposal all BMW ConnectedDrive remote
functions using the CE device such as locking and unlocking the
doors, the activation of the horn or headlamp flasher for locating
the vehicle within sighting or hearing range, the CarFinder for
locating the car within a radius of up to 1,000 metres as well as
the Google Local Search function.
In addition, new remote
functions developed especially for the BMW ActiveE for battery
charge control and vehicle preconditioning have been incorporated
into the range of functions. Via the customer’s Connected Drive
Account the iPhone application establishes a unique connection with
the vehicle and automatically displays the additional range of
functions as soon as the Connected Drive Account has been
identified. This kind of connection between remote controlled
services and electric mobility is unique. However, prerequisite for
all remote functions is that both the vehicle and the user are
receiving a signal. Of course, the driver has access to the BMW
ConnectedDrive functions without using an iPhone. This serves solely
as a remote control and information device.
eCommand: charge level, range and
preconditioning at a glance.
The specific electric
car functions - eCommand in short - comprise both charge control and
control of the preconditioning of the energy storage unit and with
it the air conditioning of the interior. The charge control function
allows the user to start and finish the charging process as well as
the setting of the charge starting time via the charge timer inside
the vehicle. Via charge control the user can view the charge level
at any time and see whether the vehicle is currently being charged.
Users are informed of the battery charge level (SoC - State of
Charge), the vehicle’s current travel range with a full battery
charge and the time remaining until the batteries are fully charged.
A further display function informs users how far away they are from
work or the destination that has been predefined as their home, so
that they are able to make a best possible estimation of the
distance they are still able to travel. Moreover, the app informs
users where the nearest battery charging stations are, offering at
the same time the possibility to add these directly to the
navigation system’s routing function as an interim destination. A
statistics function with historical data pertaining to consumption
and range enables BMW ActiveE drivers to compare consumption with
other drivers on a special website.
Preconditioning for enhanced
vehicle range.
Unlike the MINI E, the
BMW ActiveE offers the user for the first time the possibility to
cool or heat both the energy storage unit and the car interior using
intelligent preconditioning, thus bringing them up to the ideal
operating temperature even before setting off. A preconditioned
vehicle offers two advantages: firstly, the ideal operating
temperature of the energy storage unit guarantees highest possible
power output and hence a longer range. Secondly, the interior is
already adjusted to a pleasant temperature prior to starting a
journey - both in the summer and the winter. Intelligent
preconditioning of the BMW ActiveE automatically determines
according to the ambient temperature to what extent the vehicle and
the battery should be pre-cooled or heated.
Preconditioning can be
activated directly or the user can determine via the timer when
preconditioning should start. For instance, he or she can ensure
that the vehicle is pre-cooled or heated in the mornings before they
use the car. However, it is only possible to precondition the car if
it is connected to a charging terminal via a battery charging lead.
This ensures that the vehicle’s range is not shortened due to the
comfort function. On the contrary, it actually increases it. Due to
the heating and cooling process while the vehicle is connected to
the power supply, the energy required for this is no longer drawn
from the battery during the journey. Charging and preconditioning
functions are, of course, also directly accessible and controllable
from inside the vehicle.
BMW ConnectedDrive assists in
assessing field test results.
Access to the vehicle
via BMW ConnectedDrive remote functions is also BMW’s feedback
channel for the data recorded during field tests. When the charging
process has finished and/or when network connectivity is
established, the vehicle sends the vehicle data history recorded
during the previous five hours to the BMW Backend for further
analysing. Here, only development-related data such as distance
travelled, maximum vehicle ranges as well as charging times and
behaviour is collected, transferred and allocated to each respective
vehicle. The objective is a comprehensive vehicle-specific
documentation in order to obtain knowledge that can be used for
further development. Anonymity of recorded data is, of course,
guaranteed at all times.
