Stellantis Will Adopt SAE J3400 Connectors For Its EVs


In a significant move towards simplifying the charging experience for electric vehicle (EV) owners, Stellantis, one of the leading automakers, has announced its adoption of the proposed SAE J3400 charging connector standard for its upcoming EV models in North America. This decision not only streamlines the charging process but also marks a pivotal step towards industry-wide standardization.

Until now, Tesla has been a trailblazer in fast charging across the U.S. and Canada with its North American Charging Standard (NACS). Since 2021, Tesla vehicles have been using this proprietary charging connector system. Tesla’s Supercharger network, established since 2012, boasts reliability and speed, offering some of the fastest charging stations across North America.

However, Stellantis is now aligning with the broader industry trend towards standardization. Tesla had introduced its own innovation, the Magic Dock connector, which allows for compatibility with both NACS and the Combined Charging System (CCS1) used by other manufacturers. While initially limited, the Magic Dock adoption signifies Tesla’s willingness to adapt to emerging standards.

The publication of the SAE J3400 Technical Information Report in December 2023 further solidified this trend. Based on NACS, the J3400 standard enables any supplier or manufacturer to utilize, produce, or deploy the connector on EVs and charging stations throughout North America.

Moreover, government support is reinforcing this shift. The Federal Highway Administration’s requirements allow for J3400/NACS adapters on federally funded DCFC chargers, alongside CCS1 connectors, enhancing compatibility across charging infrastructure.

What does this mean for drivers? It translates to greater convenience and accessibility. With more automakers embracing standardized charging connectors, concerns about compatibility and the need for multiple adapters are alleviated. Whether driving a Stellantis or Tesla EV, drivers can anticipate a hassle-free charging experience at an expanding network of stations across North America.

Yet, Stellantis is not stopping there. Collaborating with six other major automakers, they are spearheading the IONNA charging network initiative. This ambitious project aims to install at least 30,000 high-powered charge points across urban and highway locations by 2030. Notably, these stations will accommodate both the SAE J3400 and Tesla’s NACS connectors, ensuring compatibility for all EV owners.
