Green light for a "Bidirectional Charging Management (BCM)" investigate project.

Posted on 08. Nov, 2019 by in BMW Canada

Munich. The newly launched Bidirectional Charging
Management – BCM investigate plan brings together companies and
institutions from a automotive, appetite and systematic sectors. They
have teamed adult to rise technological solutions for creation electric
mobility even easier and cheaper for users, with even reduce emissions.
By adopting a holistic approach, a project’s interdisciplinary
partners are aiming to interlink vehicles, charging infrastructure and
appetite grids for a initial time in a approach that facilitates a widest
probable use of renewable appetite – and during a same time boost power
supply reliability. The investigate plan will run for 3 years
underneath a protection of a German Aerospace Centre and with appropriation from
a German Federal Ministry for Economic Affairs and Energy. Testing
of a initial 50 BMW i3 cars versed with bidirectional charging
record (i.e. that are means of backfeeding) is approaching to start
underneath real-world bland conditions in early 2021.

Not usually will electric vehicles with bidirectional charging
capability be means to pull electrical appetite for their high-voltage
battery when plugged into a concordant charging hire or wallbox,
they will also have a ability to retreat a routine and feed energy
behind into a appetite grid. This will effectively spin a electric
vehicles’ batteries into mobile appetite storage inclination that can also
supply electricity when required. Integrating as many electric
vehicles as probable into a appetite grid in this approach calls for myriad
innovations in terms of car technology, charging hardware,
charging management, communication interfaces with appetite sector
stakeholders and authorised parameters. Bringing about these advances is
a charge of a investigate project, in that a BMW Group is behaving as
consortium leader. It is assimilated by KOSTAL Industrie Elektrik GmbH
(development of charging hardware), delivery network operator
TenneT  and placement network user Bayernwerk Netz GmbH (both
appetite complement services), a Research Institute for Energy (FfE) and
Research Association for Energy (both appetite complement analysis), the
Karlsruhe Institute of Technology (KIT; investigate into electricity
marketplace and grid repercussions) and a University of Passau (user research).

Expanding electric mobility enhances appetite supply reliability.

Although a swift of electric vehicles on a roads keeps growing,
this usually formula in a slight boost in a volume of electric power
required. However, there is a flourishing need to control appetite flows
cleverly in sequence to make best use of electricity from
renewable sources. The BMW Group has already succeeded in implementing
methods of intelligent charging control in commander projects. For several
years, intelligent charging government to accommodate a needs of both the
patron and a appetite grid has been undergoing unsentimental trials in
bland conditions in California with a swift of 300+ electric
vehicles. This has paved a approach for a BMW Group to group adult with
appetite grid user TenneT to rise an innovative resolution in
Germany that allows a charging plan for electric vehicles to
cause in a customer’s mobility schedule, a accessibility of green
electricity and a stream bucket on a appetite grid. It means
plugged-in vehicles can postpone and after resume charging when
stirred by signals from a grid operator.

The bidirectional charging record (for backfeeding power) now
being explored could lead to even larger benefits. Indeed, it allows
parked electric vehicles bending adult to a charging hire or wallbox to
be used as stretchable appetite storage devices. During durations of
quite high direct for electricity, these vehicles are means to
feed additional appetite into a grid, while their high-voltage
batteries are especially charged during times when altogether direct is lower. In
this way, electricity from renewable sources can be tapped and stored
as it becomes available. And a stored appetite can, in turn, be
deployed accurately when needed, either for electric pushing or boosting
appetite grid capacity. Electric mobility can therefore assistance to stabilise
appetite grids and extent a need to enhance them, gripping electricity
prices stable.

Bidirectional charging assists a appetite revolution.

As good as improving appetite supply reliability, intelligently
tranquil formation of electric vehicles into a appetite grid can
also serve boost a suit of renewable appetite in Germany’s
altogether electricity consumption. By utilising a storage capacities
done accessible in a high-voltage batteries of electrified vehicles,
supply and direct for immature appetite can be reconciled some-more effectively.
Using these electric vehicles as a means of aegis storage allows the
intensity of breeze farms and solar plants for carbon-neutral energy
era to be exploited to an even larger degree.

For example, a over-abundance of solar appetite can be stored in a vehicles’
high-voltage batteries and after used for driving, fed behind into the
customer’s domestic network (“vehicle to home”) or sent to a power
grid (“vehicle to grid”), so that any remarkable supply bottlenecks can be
alleviated but resorting to hoary appetite back-ups from power
stations. This adds serve abyss to a purpose of electric mobility as
an unique component of a appetite revolution. Its continued spread
serves to reduce CO2 emissions both when pushing and when
generating electricity.

Fleet exam involving 50 BMW i3 models with backfeeding capability.

In serve to devising systems for vehicles and wallboxes that are
means to backfeed power, a Bidirectional Charging Management – BCM
investigate plan is also focusing on a growth of technologies
for appetite government systems, and hardware and program for
determining charging. The authorised and regulatory parameters are being
evaluated, too. Nowhere else has such an all-encompassing approach
been actively adopted. All a applicable elements and variables for
normal operation serve down a line are being deliberate from a
holistic viewpoint and aligned. The plan will enter a practical
proviso during a start of 2021. A one-year commander theatre will see 50 private
and swift business granted with a BMW i3 with backfeeding
capability, as good as a suitable charging hardware and
concomitant digital services, so they can exam out a customer
advantages of a solutions grown so distant and their usability under
real-world conditions. This will emanate a height for subsequently
implementing a record opposite a house and so confederate electric
mobility into Germany’s appetite grid.
