Mercedes-Benz and The Mobility House are pooling their expertise to intelligently connect the automaker's electric vehicles with the energy system. The cooperation includes charging solutions for private households that offer both unidirectional and bidirectional solutions.

The partnership between The Mobility House and Mercedes-Benz includes smart V1G and V2G charging solutions for private households. With V1G, the vehicle is charged intelligently and as cost-effectively as possible. In contrast, with V2G, electric vehicles can also feed electricity back into the grid. This not only generates higher revenue through energy and grid services but also feeds more renewable energy into the power grid. The Mobility House will be responsible for the integration, aggregation, and marketing of electric vehicle batteries in the partnership. Mercedes-Benz, in turn, can offer an end-to-end solution that is integrated into the automaker's charging ecosystem.

Intelligently Control Charging Processes

Mercedes-Benz is planning the gradual introduction of smart charging offers with its new electric vehicles. In a first development stage, charging processes at the home wallbox will be intelligently controlled so that charging with green electricity takes place at the best possible time, allowing users to save on electricity costs. The system charges whenever the wind blows or the sun shines and there is thus a particularly large amount of renewably generated electricity in the energy grid and electricity prices fall.

Dismantling Infrastructure for Bidirectional Charging

Within the cooperation, the development and establishment of infrastructure for bidirectional charging is a key focus. This allows electric vehicles not only to charge electricity but also to feed it back into the grid. The electric vehicle acts as an energy storage system and becomes part of the smart home system for private households as well as the entire energy grid. Users can save significantly through bidirectional charging: The energy stored in the batteries of electric vehicles can be traded on the market via vehicle-to-grid technology. This helps reduce electricity costs by purchasing excess energy cheaply during peak times and feeding it back into the grid at a financial advantage when energy demand increases.

Make Production of Renewable Energy Stable

With a high proportion of fluctuating renewable energy production, it often happens that renewable energy production has to be shut down because the grids cannot transport the energy due to a lack of capacity. An analysis by the two companies shows that as few as two million bidirectionally chargeable electric vehicles in Germany could avoid almost half of the shutdowns. This could reduce electricity costs in the entire electricity system in Germany by a three-digit million amount if the vehicles are available to support the energy market while parked and charged at home and at work. These savings would benefit all consumers in the form of lower electricity prices. (se)
