Hubject and Heliox, A Siemens Business have announced a strategic collaboration with Accelera by Cummins™, the zero-emissions business segment of Cummins Inc., and Blue Bird Corporation to deliver the first commercial deployment of an interoperable, standards compliant vehicle to grid (V2G) charging solution powered by ISO 15118-20.
This milestone marks a significant step forward for the electric vehicle (EV) industry, demonstrating the first commercial implementation of ISO 15118-20—the international standard that defines secure, bi-directional communication between EVs and charging infrastructure.
Through this collaboration:
- Hubject delivers the trusted digital infrastructure enabling secure Plug&Charge functionality, ensuring seamless authentication and authorization between vehicle and charger.
- Heliox provides advanced V2G-capable DC fast chargers engineered to meet ISO 15118-20 requirements.
- Accelera by Cummins supplies the innovative, fully integrated electric powertrains that support V2G integration.
- Blue Bird delivers electric school buses that not only draw power from the grid but also return energy back, enabling new revenue streams and enhanced grid resilience.
“This collaboration represents a turning point for the EV ecosystem,” said David Aspinwall, President, Heliox, A Siemens Business. “By combining leading-edge hardware, software, and vehicle technology with the ISO 15118-20 standard, we’re laying the foundation for a truly interoperable and scalableV2G future.”
ISO15118-20, the latest evolution of the ISO 15118 standard, supports secure, encrypted communication between EVs and chargers while enabling new functionalities such as bi-directional energy transfer, load management, and Plug&Charge authentication without RFID cards or mobile apps. This deployment proves these capabilities can work in the real world—across different brands, systems, and use cases.
“This is a major leap toward enabling a more dynamic, intelligent energy ecosystem,” said Amit Bhonsle, Head of Product – North America at Hubject. “We’re proud to support this ground breaking V2G application with our secure Plug&Charge ecosystem, built to meet the demands of ISO15118-20.”
As grid demands increase and fleets transition to electric, V2G offers immense potential for grid balancing, cost savings, and energy resilience—especially for high-utilization fleets such as school buses.
This project demonstrates that the future of eMobility is not just electric—but intelligent, integrated, and interactive.
