BMW Group has announced the introduction of bidirectional charging capabilities that allow for both electric energy storage and supply in the BMW Neuer Klasse series, set to launch in 2025.
During the first reveal of the Vision Neuer Klasse X, BMW introduced this innovative bidirectional charging feature that will signal the start of a new era for the next-generation series. With bidirectional charging technology, the battery of electric vehicles can be widely utilized as an energy storage device.
The basic bidirectional charging function to be applied in the BMW Neuer Klasse allows electric energy stored in the electric vehicle’s battery to be used as a source of power for homes, or even sold through the electricity market to generate revenue. Additionally, it can be used as a high-voltage large-capacity auxiliary battery during outdoor activities like camping. BMW customers will find it easier to transition to the electric vehicle era and contribute more readily to using renewable energy and practicing sustainability.
Bidirectional charging technology can be utilized in three main ways.
From Vehicle to Home, V2H (Vehicle to Home)
The first method is V2H (Vehicle to Home), which utilizes the vehicle’s high-voltage battery as an energy storage device to serve as a power source within the home. For instance, power generated from a solar system can be stored in the car’s battery via the ‘BMW DC Wallbox Professional’ and used to power household electronic devices, reducing energy costs.
Supplying electricity to the Grid, V2G (Vehicle to Grid)
The second is the V2G (Vehicle to Grid) method, which allows for leftover electric energy in the car battery to be supplied to the electricity grid and sold in the energy market after driving. In Europe, this process is managed by BMW’s partner E.ON, enabling customers to generate revenue. This feature is available in markets where the necessary regulations and procedures are in place.
Serving as a large-capacity high-voltage auxiliary battery, V2L (Vehicle to Load)
Lastly, V2L (Vehicle to Load) refers to using the stored electric energy in the vehicle as a power source for external electronic devices. The BMW Neuer Klasse can be utilized as a portable large-capacity high-voltage auxiliary battery to charge electric bicycles or provide power for electronic devices during camping. The My BMW app allows users to conveniently and intuitively control the V2L function and manage the ‘BMW Connected Home Charging’ ecosystem with ease.
Bidirectional charging technology is expected to enhance power supply stability, increase the use of renewable energy, and reduce the operation of fossil fuel-powered plants. This technology will make electric mobility an indispensable element in the energy revolution, contributing to reducing carbon emissions throughout the mobility and power generation processes.
