The convenience of the Tesla Supercharger network is a significant draw for electric vehicle owners, especially as Tesla opens its network to non-Tesla EVs. However, a nagging question persists for both current and prospective EV drivers: just how reliable are these charging stations? When you pull up to a Supercharger, what percentage of the time can you actually expect it to be working and ready to power up your vehicle? While precise, real-time data on Supercharger uptime is not publicly available, we can delve into anecdotal evidence and real-world experiences to understand the general reliability of the Tesla Supercharger network.
Experiences vary widely, but online forums and social media often host discussions about Supercharger availability and functionality. Users frequently share their encounters, both positive and negative, painting a picture of the network’s performance. While Tesla aims for high uptime, real-world scenarios can introduce complexities.
Recently, we conducted a test at a Supercharger station in Brewster, N.Y., located at 1 Starr Ridge Road. Our experience, while limited to a single location and a short timeframe, offers a glimpse into potential real-world issues. Driving both a Kia EV6 and a Mercedes-Benz EQE, we encountered a situation where the initial Supercharger station we attempted to use with the EV6 failed to initiate charging.

Despite proper connection and initial communication between the EV6 and the charging station, the charging process faulted and stopped within 30 seconds. Moving to a different charger at the same location resolved the issue for the EV6, and the Mercedes-Benz EQE charged without incident on its first attempt. This experience highlights that even at a single station, some individual chargers might be temporarily out of service or experiencing issues.

Beyond isolated incidents, broader factors can influence the perceived reliability of Superchargers. Station age, usage frequency, and even environmental conditions can play a role. Stations in high-traffic areas might experience more wear and tear, potentially leading to more frequent maintenance needs. Tesla is continuously expanding and upgrading its Supercharger network, introducing newer V4 Superchargers which are designed to be more robust and user-friendly, including longer cables that address some of the accessibility issues encountered with non-Tesla vehicles at older stations.
While it’s challenging to pinpoint an exact percentage of Tesla Superchargers working at any given moment, the general consensus suggests a high degree of reliability. However, like any complex infrastructure, occasional outages and malfunctions are inevitable. User reports and experiences, such as our test in Brewster, indicate that while most Superchargers are functional, encountering a non-working station or a faulty charger is a possibility. For EV drivers, especially those embarking on long journeys, checking real-time Supercharger status on the Tesla app or third-party apps can be a helpful step to mitigate potential charging disruptions and ensure a smoother and more reliable charging experience.
