In addition to exhibits and demos, the Forum in October will showcase a platform for demonstrating the end-to-end communications and power flow functionality of V2G standards-based products.

Currently, no industry standard system exists for end-end V2G testing and certification. A key goal of this testbed is to create and demonstrate such an environment.

Companies and organizations are invited to participate in this pioneering Testbed. If you have standards-compliant V2G devices, software or equipment that could be used in this showcase Testbed, please fill out the survey here.

Note: Answers to this survey will be held in confidence by SGO and will only be shared with organizers of this event, until such time as final components of the Testbed are made public. Responses are due by Thursday, July 16.

V2G End-to-End Testbed

Testbed Objective

Organizations that wish to have their components or software showcased in the Testbed should complete the inventory survey. Based on survey responses, the Testbed Working Group will select standards-compliant devices, components and software that will be used in the Testbed in October. Organizations will be notified of the status of their nominated components by the end of July.

The V2G Testbed seeks to deliver foundational test and development capabilities enabling end-to-end communications and power flow evaluations for V2G.* The intent of this activity is to seed industry stakeholders with foundational capabilities supporting the formalization of interoperability processes and conformance testing for the delivery of energy services. This will enable test equipment manufacturers to support validation capabilities so that regulatory stakeholders, NRTLs, Utilities, AHJs, Energy Market Operators, Resource Aggregators, auto OEMS, EVSEs and telematics providers can observe and confirm compliance to standards with the goal of establishing certification criteria and processes. Ultimately this enables end customer satisfaction, VGI sector scalability and multi-stakeholder benefits in the energy domain.

The specific goal of the V2G Testbed in October is to demonstrate a standards-based, end-to-end interoperable system for a specific use case – ie., energy services.

Testbed Configuration

In this testbed, actual chargers and EV products can be substituted for the EVSE and EV simulators above. Otherwise, EVSE and EV simulators would simulate both compliant communications protocol and electrical behaviors. The goal is to demonstrate complete end-end functionality and compatibility with simulated systems; simulated and devices/systems to be tested should pass any available certifications for protocols and safety standards – e.g., UL 1741 SB or SC. The procedure would be to start with one device/system under test -- substituting for a simulation system and validating interoperability. Additional device/systems could then be substituted for other simulation systems and be tested in the V2G End-End testbed, validating functionality with multiple real products.

The testbed demo will provide a testbed for V2G systems (UL 1741 SB), as well as protocols testing (utility DERMS to CNO/aggregator, and CNO/aggregator to EVSE). Additionally, the event will include a UL 1741 SC test setup (EVSE oversight tests) as well as an SAE J3072 testbed, if available by this time.

(Note: Diagram above depicts V2G AC end-to-end testbed. For V2G DC everything is the same except the specific requirements for messaging and behaviors between the EV and EVSE)

* Future iterations of the Testbed may be expanded to include a broader range of applications such as V1G, V2H, V2B, V2V, etc, but for October 2026 the scope is focused on V2G
