Underwriters Laboratories (UL) has issued its first certification to UL9741 and UL1741 SA for an AI-driven vehicle-to-grid compliant EV charger to Virginia-based Fermata Energy.

This milestone should help build confidence in vehicle-to-grid (V2G) electric vehicle technology by demonstrating compliance with safety and performance UL standards and applicable safety and environmental regulations.

UL9741 is the standard for bidirectional EV charging system equipment and UL1741 is the standard for inverters, converters, controllers and interconnection system equipment for use with distributed energy resources. Supplement SA is for a V2G compliant electric vehicle (EV) charging system.

Fermata Energy has created an artificial intelligence-driven V2G bidirectional software platform.

Fermata’s FE-20 bidirectional EV charging system is the first V2G-compliant EV charger to achieve certification to UL9741 and UL1741 SA. UL1741 SA addresses inverters and other utility-interconnected distributed generation equipment for grid support functions, enabling smarter, safer reactive grid interconnection. The FE-20 was designed for Fermata Energy by Heliox, a provider of fast-charging technology.

“With Fermata Energy achieving the first UL9741 and UL1741 SA certification of a vehicle-to-grid compliant bidirectional EV charger, UL is helping to build trust in this technology among fleet managers, consumers and other stakeholders,” said Milan Dotlich, vice president at UL. “We continue to monitor technical developments and regulatory changes to help enable innovation and speed to market as the future of mobility evolves.”

Tony Posawatz, CEO of Fermata Energy (fermataenergy.com), added: “Achieving the first UL9741 and UL1741 SA certification for a vehicle-to-grid compliant bidirectional EV charger is a remarkable milestone for Fermata Energy. UL’s safety science expertise in EV charging and the power grid was invaluable in helping us demonstrate for the first time that V2G bidirectional charging can be achieved while meeting the safety requirements of UL standards. We are grateful for UL’s commitment to help us solve these complex challenges and support the future of mobility and the energy industry.”

This achievement builds on UL’s first certification to UL9741 for Fermata Energy’s FE-15 charging system in 2020. The UL9741 standard covers bidirectional EV charging equipment that charges EVs from an electric power system (EPS) and includes functionality to export power from the EV to an EPS.
