Public Charging Experience for Electric Vehicle Owners Can Get Much Better, J.D. Power Finds

While most electric vehicle (EV) owners primarily charge their vehicles at home, public charging is a significant part of the EV ownership experience.

Owners’ ability to recharge their vehicle’s battery is a key factor in the broader adoption of EVs, particularly among those who can’t install a private home charger or don’t have access to residential charging, such as city dwellers who reside in multiple-occupancy buildings.


In the inaugural J.D. Power U.S. Electric Vehicle Experience (EVX) Public Charging Study, released Aug. 18, Tesla Destination ranks highest among Level 2 charge point operators with a score of 689 (on a 1,000-point scale) and Tesla Supercharger ranks highest among DC (direct current) fast chargers with a score of 733.


“Public charging infrastructure is a key component in the overall adoption of electric vehicles by the broad population,” said Brent Gruber, senior director of global automotive at J.D. Power. “Unfortunately, the availability of public charging is the least satisfying aspect of owning an EV. Owners are reasonably happy in situations where public charging is free, doesn’t require a wait and the location offers other things to do---but that represents a best-case scenario.


"The industry needs to make significant investment in public charging to assure a level of convenience and satisfaction that will lure potentially skeptical consumers to EVs.”


The study measures EV owners’ satisfaction with two types of public charge point operators: Level 2 charging stations and DC fast charger stations.


Satisfaction is measured across 10 factors: ease of charging, speed of charging, cost of charging, ease of payment, ease of finding this location, convenience of this location, things to do while charging, how safe you feel at this location, availability of chargers and cleanliness of this location.


Following are key findings of the 2021 study:


Most owners satisfied with ease of public charging: Satisfaction with the ease of using a DC fast charger is 737 among battery electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV) owners, while satisfaction with the ease of charging at a Level 2 charging station is...
