Automaker Consortium’s Charging Network Claims Top Spot in Debut Ranking
IONNA, a joint venture backed by BMW, General Motors, Honda, Hyundai, Kia, Mercedes-Benz, Stellantis, and Toyota, achieved a score of 807 out of 1,000 in JD Power’s 2026 US Electric Vehicle Experience Public Charging Study, earning the highest satisfaction rating among fast-charging networks. This marks IONNA’s first year of eligibility for the study, where it surpassed the Mercedes-Benz Charging Network (797) and Rivian Adventure Network (755) to become the most trusted charging provider among US electric vehicle drivers.
JD Power’s study noted that IONNA excelled in key metrics such as charging convenience, speed, and availability, with several scores exceeding the industry average by over 100 points. As of mid-August 2026, IONNA has deployed 150 charging stations across the US, totaling 1,375 charging ports, and continues to expand its network. CEO Seth Cutler stated that IONNA utilizes Alpitronic hardware paired with in-house-developed software, measuring charger reliability by the first-attempt success rate. He emphasized the company’s commitment to redefining public charging quality and service standards.
Charging Stations with Integrated Amenities Become a Key Advantage
IONNA’s “Rechargery” sites combine high-power DC fast chargers with amenities such as canopies, restrooms, food services, lounges, and multiple charging stalls, addressing diverse driver needs during charging sessions. JD Power’s survey revealed that such integrated charging stations received high praise from users, with fast chargers located at hotels achieving the highest satisfaction score of 692. Gas stations and convenience stores (689) and restaurants (688) followed closely, while dealership chargers scored only 570, and independent parking lots and garages received 606. The findings underscore the importance of charging station environments in enhancing driver experience.
