BMW Neue Klasse models scheduled for launch in 2025 will be equipped with technology for bidirectional charging. Functions such as “Vehicle to Home”, “Vehicle to Grid” and “Vehicle to Load” will be available to BMW customers for the first time. This move also underlines the ongoing expansion of the BMW Group Charging offer.
“Starting this summer, we will be offering cost-optimized 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”, says Frank Weber, member of the Board of Management of BMW AG, responsible for Development.
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.
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.
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.
