Key Takeaways
- Tesla and Rivian charging networks report significantly fewer problems compared to third-party providers.
- Hardware-related issues are the most common problems encountered at public charging stations.
- Consumer Reports suggests optimizing charging experiences by using multiple payment methods and following best charging practices.
Charging Network Performance Compared
A recent Consumer Reports survey highlights significant disparities in the reliability of electric vehicle (EV) charging networks. The survey examined over 5,700 public charging sessions, involving responses from 1,230 EV and plug-in hybrid owners, revealing that charging networks managed by automakers, specifically Tesla and Rivian, experience far fewer issues compared to third-party providers like Shell Recharge, EVgo, and Blink.
The survey found that EV owners encountered problems in 20% of their public charging sessions. Notably, issues were reported at Tesla stations just 4% of the time and at Rivian chargers 5% of the time. In stark contrast, problems occurred at Shell Recharge stations 48% of the time, at EVgo stations 43% of the time, and at Blink stations 41% of the time. This underscores a trend where chargers managed by automakers perform significantly better than those owned by independent operators.
Common Issues Experienced
The survey identified hardware-related issues as the primary concern, making up 36% of reported problems. This was a shift from previous years when payment issues were more prevalent. The survey found that 25% of reported issues fell under “other,” while 23% were payment-related and 15% involved charging power.
Among the hardware problems, malfunctioning screens were predominant at 76%, followed by damaged cables or connectors (10%) and issues preventing the charger from connecting to the vehicle, such as ice blockage (9%). Some drivers faced cables that were too short (5%).
Payment issues still affected a significant number of users, with 56% reporting they managed to pay but encountered problems preventing charging. Additionally, 25% could not complete their payment at a particular charger and had to look for another, while 19% experienced charging failures despite successful payments.
Improving Charging Experiences
To alleviate difficulties at public charging sites, Consumer Reports recommends that EV owners set up multiple accounts with saved payment information. This way, if a charger’s interface malfunctions, users can still complete payments via an app associated with the network.
Another suggestion includes adhering to general charging best practices, like limiting fast charging to 80% and preconditioning the battery before arrival. Surveys indicate that users prioritize getting a charge reasonably quickly over the actual charge rate, illustrating a demand for charging convenience.
As new competitors, like the automaker-backed Ionna, expand their networks, future evaluations may reveal changes in consumer satisfaction and performance among charging providers.
