A new J.D. Power survey shows driver frustration with public charging stations.

Fill It Up!

Additional, functioning public charging stations needed to satisfy EV drivers.

A recent J.D. Power report notes drivers of plug-in hybrid vehicles and battery-electric vehicles, especially those in high-volume markets including California, Texas and Washington, find public charging stations inadequate and often nonfunctioning.

“Public charging continues to provide challenges to overall EV adoption and current EV owners alike,” says Brent Gruber, executive director-global automotive at J.D. Power. “Not only is the availability of public charging still an obstacle, but EV owners continue to be faced with charging station equipment that is inoperable.”

Although most EV owners charge their cars at home – between 70% and 80%, according to a 2021 report by the Fuel Institute – the lack of operable charging stations frustrates owners. Charging company spokespeople recently interviewed by The New York Times disputed studies and anecdotes detailing the dearth of operable chargers but lamented the lack of maintenance on some.

There’s no disputing customers’ responses to their satisfaction with public charging stations as reported by J.D. Power.

Customer satisfaction with public Level 2 charging declined from last year, dropping to 633 (on a 1,000-point scale) from 643 in 2021, while satisfaction with the speedier DC (direct current) fast-charger segment remained flat at 674. Currently, only a handful of vehicles can take advantage of the fastest charging speeds, notes J.D. Power.

J.D. Power analysts say the lack of progress points to the need for improvement. While EVs are gaining wider consumer acceptance, the shortage of public charging availability is the No.1 reason vehicle shoppers reject EVs.

Tesla Destination ranked highest among Level 2 charge point operators with a score of 680 and Tesla Supercharger ranked highest among DC fast chargers with a score of 739, the J.D. Power survey shows Tesla says it plans to open its 1,600 charging stations and 16,000 charging points to other automakers’ models.

Gruber notes the National Electric Vehicle Infrastructure (NEVI) Formula Program promises to provide funds to states for building out their EV public charging infrastructure. Although this will lead to sizable growth in the availability of EV charging stations, it likely won’t satisfy demand.

“Stations need to be added to areas where there are currently gaps in heavily traveled routes and in high-density areas for people who don’t have access to residential charging, but most importantly, designed with things for users to do while charging — regardless of the use case, he says. “Then, we need to make sure those stations are reliable.”

The 2022 U.S. Electric Vehicle Experience Public Charging Study included 11,554 owners of battery-electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). The study was fielded from January through June 2022. Findings included:

  • Most owners relatively satisfied with ease of charging process: Satisfaction with the ease of charging at a DC fast charger was 745 on a 1,000-point scale among BEV and PHEV owners, and satisfaction with the ease of charging at a Level 2 charging station was 699. This indicates that current EV owners understand the operation of both types of chargers, so the systems themselves do not prompt issues. But virtually all other attributes related to public charging score lower. Some, like cost of charging, were much lower: 473 for DC fast chargers and 446 for Level 2 chargers.
  • Public charger operability and maintenance a key issue: Growth of the public charging infrastructure makes it easier for EV owners to find public charging stations. The index for ease of finding a location was 724 among users of DC fast chargers and 683 among users of Level 2 chargers. J.D. Power analysts note the industry needs to do a better job of maintaining existing charging stations. The study found that one out of every five respondents ended up not charging their vehicle during their visit. Of those who didn’t charge, 72% indicated the station was malfunctioning or out of service.

“Everyone knows that the landscape of gas stations is focused on convenience – readily available, fast fueling and quick convenience items,” Gruber says. “Although fast charging is seemingly getting faster by the day, to expedite the charging process vehicles will need to accommodate the newest ultra-fast chargers. Currently, only a handful of vehicles can take advantage of the fastest charging speeds.

“And no matter how fast their vehicle charges, EV owners still indicate they need more options for things to do during each charging session to enhance convenience and fill the downtime.”
