The Challenge of Defective EV Chargers in Non-Tesla Charging Network

Tesla has long been recognized for its robust charging network, setting the standard for other electric vehicle (EV) makers. However, as more companies strive to catch up and expand their own charging networks, they face ongoing challenges. The reliability of chargers at non-Tesla stations remains a significant issue, especially as electric vehicles become more commonplace.

Joanna Stern’s Experience with Non-Tesla DC Fast Charging Stations

Joanna Stern, a reporter from the Wall Street Journal, recently embarked on a journey to test all the non-Tesla DC fast charging stations in the Los Angeles area using her Rivian R1T. Despite the region being densely populated with chargers, her findings were discouraging.

High Defect Rate at Non-Tesla Charging Stations

Out of the 30 non-Tesla charging stations visited by Stern, 13 of them had some form of issue, resulting in a defect rate of over 40%. Moreover, out of the 126 individual chargers at these stations, 27% were found to be defective. The issues encountered included out-of-order signs, dead screens, error messages rendering chargers unusable, power problems, broken hardware, payment rejection, and charger-to-vehicle communication failure.

Addressing Infrastructure Challenges for Mainstream EV Adoption

For EVs to become mainstream, the auto industry must address these infrastructure challenges. The adoption of Tesla’s charging port by many manufacturers could alleviate some pressure on non-Tesla charging stations, allowing them to focus on improving their existing infrastructure while expanding further. However, this raises concerns about whether Tesla’s charging network can handle the increased demand.
