Hubject and Heliox, a Siemens business, announced a partnership with Accelera by Cummins and Blue Bird Corp. to launch what they describe as the first commercial implementation of an interoperable, standards-compliant vehicle-to-grid (V2G) charging system using ISO 15118-20.
This project represents one of the first commercial implementations of ISO 15118-20, the international standard that defines secure, bidirectional communication between electric vehicles (EVs) and charging infrastructure.
Through this collaboration:
- Hubject provides the digital infrastructure for Plug&Charge authentication and authorization between vehicles and chargers.
- Heliox supplies dc fast chargers compatible with ISO 15118-20 and supporting V2G operation.
- Accelera by Cummins provides electric powertrains designed for V2G applications.
- Blue Bird supplies electric school buses capable of transferring energy to and from the grid to support grid stability.
ISO 15118-20 defines secure, encrypted communication between EVs and chargers and supports functions such as bidirectional energy transfer, load management, and Plug&Charge authentication without RFID cards or mobile applications. This deployment demonstrates interoperability among different hardware and software systems.
As grid demand increases and fleets transition to electric vehicles, V2G technology may help support grid balancing, improve energy management, and reduce operational costs for high-use fleets such as school buses.
This project demonstrates how e-mobility technologies are evolving to become more connected, interoperable and responsive within the broader energy and transportation systems.
