UL Solutions launches V2G certification programme for bidirectional EV chargers
By Eve
US testing and certification company UL Solutions has launched a certification programme for vehicle to grid technologies, enabling testing and certification of bidirectional EV supply equipment under UL 1741 Supplement SC, the standard for inverters and interconnection equipment for distributed energy resources. Products certified under the programme can work with EVs using onboard bidirectional inverters designed to SAE J3072, and can also be certified for grid interconnection under new UL 1741 multipiece distributed energy resources requirements coupled with UL 9741, the standard for electric vehicle power export equipment. Testing and certification services are available at UL Solutions laboratories in Fremont, California and Northbrook, Illinois.
Why it matters: The certification programme provides a clear compliance pathway for manufacturers developing bidirectional charging equipment, potentially accelerating V2G deployment by standardising testing requirements for equipment that bridges EVs and utility grids. For charge point operators and procurement teams, certified products offer assurance of interoperability and grid interconnection compliance, reducing technical risk in V2G projects.
