Bridging the Gap Between Mobility and Infrastructure
Experience & Expertise: As a leading player in the global energy ecosystem, the concept of Vehicle-To-Building (V2B) has evolved from a theoretical research topic to a cornerstone of modern smart cities. V2B technology allows electric vehicles to act as mobile power storage units, discharging energy back to buildings to balance peak loads and provide backup power.

Currently, the V2B market is witnessing explosive growth across Europe, North America, and East Asia. In Europe, strict carbon neutral regulations are driving commercial building operators to integrate EV fleets into their energy management systems. In North America, the focus is on grid resiliency and utilizing V2B for peak shaving in industrial parks. As a premier China V2B factory, we are at the forefront of providing the bidirectional hardware required to facilitate this transition.
The industry is moving towards Universal Interoperability. Future V2B systems will not be restricted to specific car brands or charger models. We are seeing a shift toward high-power DC bidirectional charging and the integration of AI-driven energy management software that predicts building demand patterns and vehicle departure times to optimize charging cycles.
Reduce electricity bills by discharging EV batteries during peak building demand hours.
Utilize vehicle batteries as a high-capacity UPS for critical building operations during outages.
Store excess solar/wind energy in EVs and use it when renewable generation is low.

Adapting Technology to Global Regional Requirements
Office buildings often face high demand charges during working hours. Our 7kw and 44kw bidirectional chargers allow company fleet vehicles to support the building’s air conditioning and lighting loads during the 10 AM - 4 PM peak, recharging at night when rates are lower.
In regions with fluctuating grid stability, V2B units serve as emergency power bridges. Large electric trucks and vans can power localized industrial equipment during micro-outages, ensuring production lines don't stop.
Using V2H (Vehicle-to-Home) and V2B, homeowners and apartment complex managers can store excess solar energy generated during the day in their EVs and use it to power common areas at night.
