In the US, most electric vehicle owners say public chargers are easy to use. That is, when they actually work.
a new JD Power Survey Finds that, although public charging stations have a a little easier today, faulty chargers degrade the experience and hinder the adoption of EVs. That’s not good, because the planet is only getting hotter and EVs are expected to become a main role in reducing greenhouse gas emissions in the transport sector.
Of the 11,554 owners of battery-electric and plug-in hybrid vehicles surveyed by JD Power, one in five said they “finally failed to charge their vehicle during their visit,” the report said. And of the drivers who didn’t load, “72 percent said it was because the station was malfunctioning or out of service.” The findings reflect a smaller UC Berkeley study that made headlines earlier this year.
In addition to faulty chargers, the study looked at several other factors, such as price and ‘ease of payment’.
Overall, JD Power found that US EV owners will be less satisfied with Level 2 public chargers in 2022 than they were last year. On a 1000 point scale, EV drivers gave Level 2 stations an average score of 633, down from 643 in 2021. Level 2 chargers can charge a battery electric vehicle in just four o’clockmuch better than a standard residential outlet (40-plus hours).
In contrast, the JD Power survey found that satisfaction with Level 3 chargers – also known as DC fast chargers – remained stable year over year, with an average score of 674. Level 3 chargers can fill the battery level of an EV up to 80% in less than 20 minutes, but they are much rarer.
In terms of price, the survey found that charging costs had depressed drivers’ satisfaction scores across the board. Contrary to that point, a separate survey of 2,040 US adults (paid by EV finance company Tenet) found that a whopping “81% believe that buying electric is too expensive.”
Among the EV charging companies, Tesla led the pack in JD Power’s investigation as the most beloved station operator, while EVgo and Blink were the rearguard.
