A new study shows that many electric vehicle (EV) charging networks were substantially less reliable than Tesla’s Superchargers or Rivian’s Adventure Network (RAN), while hardware problems accounted for the most common issue experienced
In a Consumer Reports study shared last week, Tesla and Rivian’s charging networks were found to be significantly more reliable than those of other companies, though EV owners reported a problem with about one out of every five charging sessions initiated overall. Respondents said they had issues with just 4 percent of charging sessions at Tesla’s Superchargers, making them the most reliable, while issues with Rivian’s network were reported for just 5 percent of sessions.
Comparatively, Shell Recharge users faced the most issues, with respondents detailing problems in 48 percent of charging sessions. The next least reliable networks were EVgo and Blink, which followed with 43 percent and 41 percent problems reported, respectively. DC fast-chargers had a reported issue rate of 34 percent, while owners faced problems with Level 2 chargers in 25 percent of sessions.
“The findings show that the public charging experience can vary widely based on the vehicle and the charging networks operating in one’s community and along frequent trips,” writes Drew Toher, Consumer Reports’ Campaign Manager for Sustainable Transportation projects. “This is an important consideration for those without access to home charging. With these findings, CR is encouraging all charging networks to take ownership of their performance and implement measures to improve reliability.”
The survey included responses from 1,230 owners of BEVs and plug-in hybrid EVs (PHEVs), detailing experiences from roughly 5,700 individual charging sessions. The majority of issues customers faced were related to hardware, while they also reported problems with payment, charging power, and other factors.
Out of those who said they had issues directly with the chargers, 76 percent said they encountered broken or unresponsive screens, or those with error messages.

“By calling out broken screens, payment issues, and slow charging power, community members are crowdsourcing data that will hold charging networks accountable and improve drivers’ experience with public charging,” Toher adds. “This will help tackle the biggest impediment for consumers looking to purchase a more efficient vehicle.”
The release also notes that EV owners planning to charge beyond their home can take a few steps to help ensure the best experiences possible, including making accounts for several different charging networks, getting apps like A Better Route Planner, Plugshare, and CR partner Chargeway, and performing battery preconditioning, among others.
Tesla’s Superchargers have repeatedly been found to be the most reliable in markets around the world, and in surveys from Consumer Reports, JD Power, and other auto industry research firms. Rivian has also followed Tesla in taking routine measures to keep owners informed about the reliability of chargers. One such example includes the automaker’s deployment last April of “charging scores” for the RAN network, to help improve customer experiences by directing them to working stations.
