Hubject, Heliox, Accelera by Cummins, and Blue Bird Announce First Commercial Deployment of International Standard-Compliant V2G Solution

Back to News Home

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 charging solution powered by ISO 15118-20.

This milestone marks a significant step forward for the electric vehicle industry, demonstrating the first commercial implementation of ISO 15118-20—the international standard that defines secure, bi-directional communication between EVs and charging infrastructure.

Hubject notes that through this collaboration:

• Hubject delivers the digital infrastructure enabling secure Plug&Charge functionality, designed to ensure seamless authentication and authorization between vehicle and charger

• Heliox provides V2G-capable DC fast chargers engineered to meet ISO 15118-20 requirements

• Accelera by Cummins supplies the integrated electric powertrains that support V2G integration

• Blue Bird delivers electric school buses that can return energy back to the grid, enabling new revenue streams and enhanced grid resilience
  

"This collaboration represents a turning point for the EV ecosystem," said David Aspinwall, President of Heliox. "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 is intended to prove 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.

Hubject notes this project demonstrates that the future of eMobility is not just electric—but intelligent, integrated, and interactive.
