A new Consumer Reports study found that some EV charging networks in the U.S. have high failure rates, with Shell Recharge stations experiencing problems 48% of the time.
Tesla Superchargers and Rivian Adventure Network were reported to be the most reliable charging stations in the U.S., while EVgo and Blink charging stations had poor reliability.
Common issues included glitchy payment systems, broken hardware, slow charging speeds, dead touchscreens, and cryptic error messages.
Charging networks like Tesla and Rivian, which design, manufacture, and operate their stations, had higher reliability due to seamless vehicle integration.
Charging station ownership fragmentation and compatibility issues between hardware and software components were cited as reasons for the unreliable charging experience.
Recommendations included improved transparency, real-time data access, better problem identification methods, and quick issue resolution by charging networks.
Drivers were advised to use community-based apps for real-time station availability, ensure battery preconditioning, and consider getting Level 2 home chargers.
19% of problems faced by EV owners involved chargers not starting despite accepting payment, emphasizing the need for charging networks to enhance reliability.
Consumer Reports urged charging networks to take ownership of their performance and implement measures to improve reliability, with a focus on broken screens and payment issues.
Crowdsourcing data through community feedback was suggested to hold charging networks accountable and enhance the overall public charging experience for EV drivers.
