Is EV Public Charging Reliability Actually Improving in 2025?

Yes, EV public charging reliability is improving in 2025, according to the latest J.D. Power study, marking a significant turnaround after years of decline. Despite overall satisfaction scores dropping due to higher costs, the core metric of successful charging sessions has reached its best level since the annual survey began. This suggests the infrastructure is finally beginning to mature and keep pace with the rapid growth in electric vehicle sales.

Why Are EV Charging Satisfaction Scores Down If Reliability Is Up?

While the fundamental experience of plugging in and getting a charge is improving, EV owners are less happy with the financial aspect. The 2025 J.D. Power U.S. Electric Vehicle Experience (EVX) Public Charging Study found that average satisfaction scores decreased to 654 for DC fast charging (down from 664 in 2024) and 607 for Level 2 charging (down from 614). This decline is almost entirely attributed to a 16-point drop in satisfaction with the cost of charging.

According to Brent Gruber, executive director of the EV practice at J.D. Power, this is a natural market evolution. "In previous years, many DC fast-charging networks kept prices low as they developed their market presence, while manufacturers regularly offered free charging incentives with vehicle purchases," Gruber stated. "However, as the infrastructure market evolves and electricity rates rise, charging prices have increased significantly in some cases, directly affecting the overall EV ownership experience."

Which EV Charging Networks Are the Most Reliable?

The study, which compiles responses from 7,428 EV and plug-in hybrid owners, ranks charging networks separately for Level 2 (slower, often found at destinations like malls) and DC fast-charging (high-speed charging for road trips). Tesla's networks continue to lead the industry, but other providers are showing competitive scores.

The rankings on a 1,000-point scale are as follows:

A key finding is that emerging networks from Ford, Mercedes-Benz, and Rivian, while not yet large enough for official inclusion, collectively scored an impressive 709—matching Tesla's top score. This indicates that newer networks are learning from past mistakes and prioritizing user experience from the start.

How Much Have Charging Failure Rates Improved?

The most promising data point from the study is the sharp decline in failed charging attempts. In 2021, 13% of charging sessions were unsuccessful. This problem worsened in subsequent years, peaking at 20%, before falling dramatically to just 14% in 2025. This improvement in reliability is a critical step forward for alleviating "range anxiety" and building driver confidence.

However, the experience is not uniform across the United States. The study found significant regional disparities:

• Pacific region owners reported the highest rate of problems, with 21% experiencing a failed charge and 12% facing wait times.
• East South Central region owners had the best experience, with only 7% reporting a failed attempt and just 5% encountering a wait.

Why Are New EV Owners More Satisfied Than Veterans?

The data reveals a split in perception between new and experienced EV owners. First-time EV buyers reported higher satisfaction scores (610 for Level 2, 654 for DC fast) than returning EV owners (592 and 648, respectively).

J.D. Power suggests this "new-car bliss" effect is likely because veteran EV owners have higher expectations. They are more critical of the current state of technology, having experienced its evolution, and are waiting for further advancements in both vehicle capabilities and charger performance that have not yet materialized.

What Does This Mean for the Future of EV Charging?

The 2025 study offers a mixed but ultimately positive outlook. The industry's focus must now expand beyond pure charging speed. As Brent Gruber cautions, "Improving reliability, ease of use, and addressing cost concerns are among a multitude of factors at play that must be prioritized to enhance the overall public EV charging experience."

For potential EV buyers, the key takeaway is that the infrastructure is becoming more dependable. While you will likely pay more to charge than in previous years, you are also more likely to have a successful session. When choosing a charging network, based on our assessment experience, Tesla's Supercharger and Destination networks currently set the benchmark for user satisfaction, but competitive alternatives are quickly emerging.
