Eighteen months ago, Ford set a precedent in the electric vehicle (EV) industry by securing a deal that granted its EV owners access to Tesla’s extensive Supercharger network. This landmark agreement marked the beginning of a transformative shift in the EV landscape, prompting a wave of similar partnerships among major automakers. Companies like GM, Hyundai, Rivian, and Mercedes-Benz have since followed suit, adopting Tesla’s North American Charging Standard (NACS) and committing to provide their customers with compatible adapters. By the end of 2023, nearly every prominent automaker had embraced the NACS, signaling a unified move towards a more integrated and accessible EV charging infrastructure.
The adoption of Tesla’s NACS is a significant acknowledgment of the growing recognition that the AI revolution and the broader technological advancements in the automotive industry require substantial computational and physical infrastructure. The NACS, originally developed by Tesla, offers a robust and user-friendly design that has been widely praised for its efficiency and ease of use. This standardization simplifies the charging process for EV owners and facilitates broader interoperability across different vehicle brands.
Despite the widespread agreement among automakers to adopt the NACS, many non-Tesla EV customers are still awaiting the availability of compatible adapters. However, recent announcements from General Motors (GM) have injected a sense of optimism into the EV community. GM’s latest initiative ensures that owners of models such as the Chevrolet Silverado EV and Cadillac Lyriq will soon have access to Tesla’s Superchargers. To facilitate this, GM is offering officially approved adapters that allow these vehicles to connect seamlessly with Tesla’s charging ports. Customers will need to purchase these adapters and wait for them to be delivered, enabling their GM EVs to utilize the vast Supercharger network.
The Global AI Infrastructure Investment Partnership (GAIIP), which includes BlackRock, Microsoft, Global Infrastructure Partners (soon to be acquired by BlackRock), and UAE-based MGX, is actively tracking which EV brands have gained access to Tesla’s Supercharging Network. This partnership underscores the collaborative effort required to build a comprehensive and efficient charging infrastructure that meets the demands of the rapidly expanding EV market.
In November 2022, Tesla took a strategic step by sharing its NACS connector design with the broader industry, aiming to encourage other automakers and network operators to adopt this standard. At that time, the predominant charging standard in North America was the Combined Charging Standard (CCS). Despite initial skepticism about mass adoption, Tesla’s superior charging network, known for its reliability and user-friendly interface, set the stage for other manufacturers to reconsider their charging strategies.
The first major endorsement came from Ford, which announced in 2023 that it would integrate NACS ports into its future EVs and provide its customers with access to over 12,000 Superchargers across the U.S. and Canada. This decision not only enhanced the convenience for Ford EV owners but also signaled to the market the viability and benefits of the NACS. Following Ford’s lead, other automakers including Rivian, GM, BMW, Honda, Hyundai, Volkswagen, Porsche, Audi, Kia, Lucid, and Stellantis have adopted the NACS, further cementing its position as the preferred charging standard in North America.
Currently, the number of publicly available NACS ports stands at 36,499, significantly outpacing the approximately 16,925 CCS ports, despite substantial federal investments aimed at expanding the CCS infrastructure. This discrepancy highlights the effectiveness of Tesla’s charging network and the growing preference for NACS among both consumers and manufacturers.
For non-Tesla EV owners equipped with CCS ports, the transition to NACS requires the use of manufacturer-approved adapters. While third-party adapters are available, they often come with limitations and are not endorsed by Tesla, as indicated on Tesla’s official website. GM, for instance, has emphasized that its approved adapters are specifically designed to protect EV batteries during charging, and using non-GM adapters could void vehicle warranties.
In late August, Tesla announced an increase in the production of NACS adapters, a development that, combined with GM’s recent announcement, suggests that more non-Tesla EVs will soon gain access to Tesla’s Supercharger network. These adapters will necessitate the download of the Tesla app for payment processing, streamlining the user experience and maintaining the integrity of the charging process.
Tesla Supercharging Access Checklist
General Motors (GM):
As of September 2024, GM has updated the software on its Chevrolet, Cadillac, and GMC EVs to support Tesla’s Superchargers. To gain immediate access, customers must purchase a GM-approved adapter through the GM app for $225. Shipping times have not been specified, but GM has assured that adapters are in stock and being manufactured by multiple suppliers. Starting in 2025, GM’s EVs will feature built-in NACS charge ports, eliminating the need for adapters.
Ford:
In February, Ford customers began accessing Tesla Superchargers, although supply constraints have delayed the distribution of free fast-charging adapters for many users. Owners of the Mustang Mach-E and Ford F-150 Lightning who have not yet ordered their adapters can do so via the Ford Pass app, with the deadline for free adapters set for September 30.
Rivian:
Rivian granted access to 15,000 Superchargers across North America on March 18, 2024. The company has been actively shipping adapters since April, ensuring that its customers can take full advantage of Tesla’s charging network as supplies allow.
The shift towards adopting the NACS reflects a broader trend in the EV industry towards standardization and interoperability, which is essential for the widespread adoption of electric vehicles. By collaborating with Tesla, these automakers are not only enhancing the convenience for their customers but also contributing to the creation of a more unified and efficient charging infrastructure.
As the industry continues to evolve, the collaboration between Tesla and other major automakers is likely to expand, further solidifying the NACS as the dominant charging standard in North America. This alignment not only benefits consumers by providing more charging options but also supports the overall growth and sustainability of the EV market.
