In a landmark move for the electric mobility sector, Hubject and Heliox, A Siemens Business, have announced a strategic collaboration with Accelera by Cummins™ and Blue Bird Corporation to deliver the first commercial deployment of an interoperable, ISO 15118-20-compliant vehicle-to-grid (V2G) charging solution.
This milestone marks the first real-world implementation of ISO 15118-20, the global standard that enables secure, bi-directional communication between electric vehicles (EVs) and charging infrastructure—a breakthrough for both smart grid integration and EV fleet operations.
Partnership Roles:
- Hubject powers secure Plug&Charge authentication, providing a seamless digital infrastructure for automatic vehicle-to-charger communication.
- Heliox supplies V2G-enabled DC fast chargers, built to meet rigorous ISO 15118-20 standards.
- Accelera by Cummins offers integrated electric powertrains designed to support V2G use cases.
- Blue Bird Corporation delivers the electric school buses capable of both drawing energy from the grid and feeding it back—opening up new revenue models and strengthening energy resilience.
David Aspinwall, President of Heliox, emphasized the innovation:
“By combining advanced hardware, smart software, and robust vehicle platforms with ISO 15118-20, we’re paving the way for a truly interoperable and scalable V2G ecosystem.”
ISO 15118-20 enables key functionalities such as:
- Bi-directional energy transfer
- Dynamic load management
- Secure Plug&Charge without RFID cards or apps
Amit Bhonsle, Head of Product – North America at Hubject, highlighted the broader impact:
“This is a major leap toward a smarter, more resilient energy ecosystem. Our ISO 15118-20-based Plug&Charge platform ensures that V2G can be securely and seamlessly adopted across use cases.”
As the demand on power grids grows and the electrification of transport accelerates, V2G technologies are poised to offer critical solutions—especially for high-utilization fleets like school buses, which can serve as mobile energy assets during off-peak hours.
This collaboration not only proves that interoperable V2G technology works across brands and platforms, but also signals the dawn of an intelligent, integrated, and interactive e-mobility future.
