Public dc fast-charging reliability improved in the first half of 2026, with failed charging visits falling to a record-low 12%, according to JD Power’s 2026 US Electric Vehicle Experience Public Charging Study.
Satisfaction with dc fast chargers rose 12 points year over year to 666 on a 1,000-point scale. JD Power attributed the improvement in part to newer charging equipment and better charger availability. Satisfaction with public Level 2 charging declined 12 points to 595.
The study also found that newer OEM-backed fast-charging networks performed particularly well for charging speed and availability. IONNA ranked highest among dc fast-charging networks with a score of 807, followed by Mercedes-Benz Charging Network at 797 and Rivian Adventure Network at 755.
Charging location also influenced satisfaction. dc fast chargers at hotels, gas stations and convenience stores, and restaurants received the highest scores, while chargers at dealerships and stand-alone parking locations ranked lower.
JD Power also reported that newer OEM-backed networks posted some of the lowest failed-charge rates.
The study included responses from 6,594 battery-electric and plug-in hybrid vehicle owners and was fielded from January through June 2026.
