Arguably, one of the biggest catalysts for the EV industry’s growth was the birth of the Tesla Supercharger network. At its inception, it was the only EV charging network poised to become a nationwide fast-charging solution for Tesla vehicles, allowing travelers to drive coast-to-coast with ease.
For those unfamiliar, Tesla began with their V1 Superchargers located strategically off highways and interstates across the United States. These Superchargers were limited to a maximum output of 90kW and later 120kW via a software upgrade. Initially, these V1 Superchargers were arguably quite unattractive and didn’t seem built for longevity. Recognizing this, Tesla later introduced more fashionable charging dispensers, almost identical to the ones seen on the modern V3 Superchargers.
Over time, Tesla rolled out their V2 Superchargers, more powerful than their predecessor, supporting a maximum output of 150kW. Some V1 Superchargers were upgraded to support a 150kW output, though this was not implemented in all V1 Superchargers.
In 2019, Tesla made a significant leap with the introduction of V3 Superchargers, capable of a 250kW maximum output, a substantial upgrade from the 120-150kW limits of previous generation Superchargers. These V3 Superchargers retained the same aesthetic as the newer V2 units but featured liquid-cooled charging cables to enable their much higher speeds. These cables were thinner and more manageable compared to the thicker, stiffer, and passively cooled cables of the V2 Superchargers, greatly enhancing their usability.
Fast forward to today, Tesla has unveiled V4 Superchargers, designed with longer cables to accommodate various charge port locations for non-Tesla vehicles. This is particularly important as V3 and newer Superchargers will support the charging of non-Tesla EVs. Ford and Rivian already have access to the network via an adapter, and later this year and into the next, Chevy, Volvo, Polestar, and most other EV brands will also gain access to Superchargers in the US.
However, it’s crucial to note that V2 Superchargers do not and will not support non-Tesla EVs unless they are upgraded to V3 or newer models. Many Superchargers in the US remain V2 units, often located in rural areas underserved by EV charging infrastructure. Tesla has slowly begun upgrading a few V2 Superchargers to V3, but a larger-scale effort is needed. Upgrading these older rural V2 Superchargers to V3 would not only improve service for non-Tesla EV drivers but could also be highly profitable for Tesla, given the lack of competition in these areas.
Previously, we reported on the challenges faced by non-Tesla drivers traveling to the Outer Banks of North Carolina, where the lack of CCS chargers and the presence of only V2 Superchargers on part of the route pose potentially significant challenges for non-Tesla EV drivers. Upgrading these spots could be highly beneficial, providing a vital service and an opportunity for Tesla to tap into a lucrative market.
With the recent restructuring of Tesla’s Supercharger team, there’s hope that Tesla will prioritize upgrading existing sites. This would enhance road-tripping experiences by offering faster charging speeds and accommodating non-Tesla EVs, allowing worry-free travel for all EV drivers. The future of the Supercharger network looks promising, and with strategic upgrades, it can continue to lead the EV charging industry.
