The U.S. public EV fast-charging network added significant capacity and saw higher utilization in 2025, according to Paren’s State of the Industry Report: U.S. EV Fast Charging — Full Year 2025.
Paren, an EV charging performance and data insights provider, reports that more than 18,000 new DC fast-charging ports were added in the U.S. during 2025, representing roughly 30% year-over-year growth. The expansion increased total fast-charging capacity nationwide and marked the largest single-year increase recorded by Paren.
Charging demand rose alongside infrastructure growth. The report estimates approximately 141 million public fast-charging sessions occurred in 2025, also an increase of about 30% compared with 2024. Despite the rapid expansion in ports and sessions, Paren notes that overall network utilization remained stable.
The report also highlights changes in how charging infrastructure is being deployed. Operators increasingly built larger charging sites with more ports per location, rather than smaller individual installations. Paren states that average station size increased as networks focused on higher-throughput locations.
Tesla added 6,786 Supercharger ports in 2025, more than any other operator, though Paren notes Tesla’s share of new fast-charging capacity declined as non-Tesla networks expanded. The report shows continued diversification among charging providers.
Higher-power charging equipment became more common in 2025, with a growing share of newly installed ports capable of delivering 250 kW or more. Paren also reports increased deployment of the North American Charging Standard (NACS) connector by non-Tesla networks, while CCS connectors continued to dominate outside of the Supercharger network.
Geographically, Paren identifies California, Texas, and Florida as leading states for new fast-charging port additions in 2025, while also noting growth across a broader range of states.
The report states that NEVI-funded deployments accounted for a small portion of total expansion, with 99 NEVI stations and 497 ports installed during the year, representing roughly 3% of new DC fast-charging ports added in 2025.
