Munich. BMW Neue Klasse models scheduled for launch
in 2025 will be able to store electricity and function as a power
outlet. They are equipped with technology for bidirectional charging –
i.e. the ability to both accept and supply electricity.
With the latest design studies, the BMW Vision Neue Klasse sedan
and the BMW Vision Neue Klasse X SAV, the BMW Group is showing what
the next generation of core vehicles from the BMW brand will look
like. They represent the range of technological innovations with which
the company is showcasing its future viability.
With the world premiere of the BMW Vision Neue Klasse X, BMW is
now announcing another innovation set to enter series production: the
ability to charge bidirectionally. This technology makes it possible
to use the high-voltage battery of an all-electric vehicle as an
energy storage device and to return the cached electricity to either
your own household supply or the power grid at a later stage.
This makes it even easier for BMW customers to actively
contribute to the energy transition and promotes the sustainable
generation and use of renewable energy. Functions such as “Vehicle to
Home”, “Vehicle to Grid” and “Vehicle to Load” will therefore be
available to BMW customers for the first time. This move also
underlines the ongoing expansion of the BMW Group Charging offer.
“We are constantly improving our range of charging products and
services in order to maximise the benefit to the customer,” says Frank
Weber, member of the Board of Management of BMW AG, responsible for
Development. “Starting this summer, we will be offering cost-optimised
charging together with our partner E.ON in a number of markets. And
with the Neue Klasse we will be taking the next step: bidirectional
charging. Vehicle to Home and Vehicle to Grid, all fully integrated
into our comprehensive charging ecosystem – BMW Connected Home
Charging. Using the vehicle, the My BMW App, the BMW backend – plus a
BMW DC Wallbox Professional and their photovoltaic system, customers
will be able to control the energy flow in such a way that home
charging is possible off grid at times. And, of course, they will also
be able to lower their charging costs by feeding the electricity
stored in their BMW back into the power grid.”
Vehicle to Home: electricity for your household
In the technology’s initial stage, bidirectional
charging will enable customers to essentially use their vehicle’s
high-voltage battery as a stationary energy storage device. Here, the
carbon-neutral electricity generated by the customer’s photovoltaic
system is temporarily stored in the vehicle’s battery with the help of
the BMW DC Wallbox Professional and then subsequently fed back to
power other consumers in the home, making the customer independent
from the external power grid for a time and reducing their energy costs.
Vehicle to Grid: feeding into the network
The second stage of bidirectional charging will allow
customers to make a portion of their battery’s capacity available
externally. This energy capacity can be used for both charging from
the grid and discharging electricity into it at appropriate times.
Access to the energy market is provided by BMW cooperation partner
E.ON. To do this, customers will need the dynamic electricity tariff
from E.ON, who will manage the charging process together with the BMW
backend to enable revenue generation from the energy
exchange.
This function will only become available in the
various markets once the necessary regulatory measures have been adopted.
Vehicle to Load: the car as a power bank
The vehicle to Load function allows energy stored in
the vehicle to be used for powering external electrical equipment.
This means the Neue Klasse can double as a form of mobile power bank
for charging an e-bike, for example, or supplying energy to electrical
equipment while camping.
Regardless of which type of bidirectional charging is used, the
customer's desire for mobility always comes first. This is ensured by
intuitive and easy operation in the My BMW App, which can be used to
control the entire BMW Connected Home Charging ecosystem.
Accelerating the energy transition
Bidirectional charging not only ensures greater
supply security. By both accepting and supplying electricity, electric
vehicles can make a significant contribution to the share of
electricity consumption coming from renewable sources. Using the
storage capacities provided by high-voltage batteries allows supply
and demand in the area of green electricity to be better coordinated.
For example, electric vehicle storage systems can selectively absorb
peak wind and solar energy generation and release the electricity
again during periods of low generation (night, lulls) in supply. This
makes it possible to reduce the start-up of fossil power plants and
their emissions during such periods. In this way, electric mobility is
becoming an ever more integral part of the energy revolution. With
bidirectional charging, CO2 emissions can be reduced both
in the area of mobility and in power generation overall.
