Optimizing Energy Usage in Commercial Buildings with Bidirectional Charging

With a V2B charging system, EVs can store excess energy generated through sustainable sources during the day and discharge it into the building during periods of lower energy production or higher demand. This reduces grid dependence, lowers energy costs, and maximizes the use of renewable energy.​

V2B technology provides commercial buildings with several key benefits:​
Cost reduction ​
By charging EVs when electricity prices are lower and discharging the stored energy during periods of higher grid costs, buildings can lower expenses and reduce their reliance on the grid.​

Maximized use of clean energy​
Energy stored in EVs from solar production can be used when needed, improving the efficiency of on-site renewable energy.​

Enhanced energy flexibility​
V2B enables buildings to adjust their energy usage based on fluctuations in energy production, offering greater control over consumption.​

Backup power​
In case of power outages, EVs serve as reliable backup power, ensuring continuity for critical building operations.​

Peak shaving​
Thanks to V2G, whenever energy consumption of a building is peaking, electricity can be taken out from the EV batteries instead of taking them from the grid and if this opportunity is systematically being utilized, then the given building will have lower electricity readiness needs, and consequently much lower electricity bills. ​

The V4Grid project is testing V2B technology in commercial buildings across Europe, with pilot sites in Bratislava, Košice, Szolnok, and Gdansk. These real-world implementations will demonstrate the practical benefits of V2B, support policy development, and encourage the broader adoption of this technology, contributing to a more sustainable and resilient energy future.
