Public Electric Vehicle (EV) Charging Station Standards and Inventory Requirements

The Massachusetts Division of Standards must issue regulations to inventory EV charging stations and ensure the accuracy of pricing and electricity volumes at public stations, including setting minimum requirements for how pricing is communicated and displayed. Stations cannot be shut down due to the division’s inability or omission to test, inspect, seal, or inventory equipment or to verify pricing/volume accuracy. Regulations may vary by technology, power level, networking status, number of chargers per site, site ownership, and inclusion of mobile solar units; they do not apply to chargers at residential properties with up to four units, and the division may set data formats aligned with industry best practices. By May 1 each year, the division must report its inventory and related activities to designated legislative committees and state secretaries, and it may set different requirements for publicly funded/available chargers than for other stations.
