Witnesses urge phased real‑time EV charger data requirements, focus on publicly funded stations

Summary
Environmental advocates and industry witnesses told the Senate Transportation committee that real‑time data on EV fast chargers can reduce range anxiety, and urged aligning state requirements with federal NEVI standards; advocates proposed starting with publicly funded or ratepayer‑funded chargers and phasing in broader requirements.
Environmental advocates and charging‑network operators told the Senate Transportation committee on April 13 that requiring universal real‑time data for public EV chargers would improve driver confidence and help expand electric vehicle adoption — but they urged a phased approach focused first on public or ratepayer‑funded stations.
Anthony Arvino, representing the Conservation Law Foundation, told the committee that Vermont’s transportation sector is the largest in‑state source of greenhouse gases and urged the panel to include real‑time charging data language in the transportation bill (referred to in testimony as H 9 44). Arvino said universal data could reduce "range anxiety" and improve the driving experience, and placed an American Enterprise Institute study into the committee record that, according to his testimony, projects a substantial national increase in EV sales if universal real‑time data were implemented.
Arvino recommended a phased rollout that starts with publicly funded and ratepayer‑funded chargers — aligning state requirements with federal NEVI (National Electric Vehicle Infrastructure) standards and taking cues from Massachusetts and California regulation — rather than immediately applying requirements to every existing charger. He said a phased approach would allow industry and regulators to learn how to implement monitoring and compliance systems without overloading a single state agency. "CLF applauds and very much supports the ultimate goal of requiring universal free real time data availability from all publicly available chargers," he said in testimony.
Emily Kelly, director of U.S. public policy at ChargePoint, said ChargePoint supports redlined amendments that align state data obligations with NEVI and existing industry standards (OCPI). She told the committee the draft language appropriately focuses obligations on publicly funded and ratepayer‑funded chargers and that mirroring NEVI will help avoid a 50‑state patchwork of different data standards. Kelly also cautioned that ChargePoint does not always know when a specific station has received public or ratepayer funding and asked the committee to clarify which stations would be covered so network operators can comply. "We need help in the state letting us know which stations this applies to," she said.
Committee members asked staff to prepare a single draft that brackets alternative language so members could compare the advocate and industry proposals. Several senators and staff raised operational follow‑up questions — about whether rates would fluctuate in real time, how often status data must be updated, network uptime and privacy protections — and asked witnesses to provide answers after the hearing.
The testimony noted that NEVI requires updates at one‑minute intervals and that California regulations have adopted a similar standard; advocates placed a report from the American Enterprise Institute into the record and argued the measure could raise EV shares of new vehicle sales nationally. Witnesses also flagged the administrative work of tracking which charging stations receive public or ratepayer funding and suggested assigning monitoring responsibilities across agencies rather than concentrating them in a single office.
