For many years, attitudes toward the nation’s public electric vehicle charging infrastructure did not match the growing popularity of the vehicles themselves.

According to a recent survey, that dynamic is changing. Earlier this month, market analyst JD Power and Associates released the findings of its annual U.S. Electric Vehicle Experience (EVX) Public Charging Study. The findings reveal that the public charging experience for owners is getting better in many ways.

For example, the study makes two findings whose divergence is notable. On the one hand, satisfaction with DC fast chargers has improved dramatically, rising 12 points to 666 on a 1,000-point scale since the last study one year ago. At the same time, noncharging visits, which are defined as those in which an EV owner arrives at a public charging station but is unable to charge the vehicle, have fallen to the lowest level ever recorded in the study.

The study measures satisfaction based on 10 factors. Charger availability showed the biggest increase, with a 27-point improvement. It was followed by safety at charger locations and the cost of charging, both of which improved by 18 points.

While satisfaction with DC fast chargers showed the greatest improvements, level 2 chargers did not fare as well, declining 12 points from last year.

Among other findings, the study noted that location plays a large role in the charging experience. Satisfaction is highest for DC fast chargers located at hotels, followed closely by gas stations and convenience stores, and restaurants.

The study also rated and compared the charging experience based on manufacturer charging stations. In that category, IONNA, Durham, N.C., ranks highest among DC fast chargers, with a score of 807. The Mercedes-Benz Charging Network, New York, ranks second at 797, and the Rivian Adventure Network, Irvine, Calif., ranked third at 755. Tesla Superchargers, Austin, Texas, came in fourth at 701.

“The public charging experience is becoming more consistent, and that’s critical as the EV market matures,” said Brent Gruber, executive director of global automotive and managing director of the EV practice at JD Power.

The study, which examined the responses of nearly 6,600 owners of battery electric vehicles and plug-in hybrid electric vehicles, is in its sixth year.
