Tesla announced that it is opening its Supercharger network to non-Tesla electric vehicles, with Ford and Rivian being the first non-Tesla brands to utilize the charging stations. The process of opening up the Supercharger network has been gradual rather than an all-at-once situation, with nearly every major EV brand selling cars in the U.S. expected to offer Tesla Supercharger access and adopt the automaker’s NACS port for future EVs by the end of 2024. However, the rollout has varied in speed for each brand.
Currently, owners of EVs from most non-Tesla brands must use an adapter to connect to Supercharger stations until new cars with NACS ports are widely available. This transition has recently started with the 2025 Hyundai Ioniq 5 and has been facilitated by the formalization of NACS as a true standard by the SAE in late 2023. In addition to hardware compatibility, automakers are also updating their software to allow proper interfacing with Supercharger stations for plug-and-charge operation, as well as integrating Supercharger stations into in-vehicle route planning and payment apps.
Ford was one of the first automakers to provide adapters for customers to fast-charge at Supercharger stations, starting in February 2024. Other automakers have followed suit, with a few more confirmed to offer adapters in the first half of 2025. Among the automakers that currently have Supercharger access are Ford, Rivian, General Motors, Volvo, Polestar, and Nissan. Automakers such as BMW, Genesis, Hyundai, JLR, Kia, Lucid, and Mercedes-Benz are expected to gain Supercharger access soon, according to Tesla.
One challenge facing automakers with 800-volt charging capabilities is that Tesla’s V3 hardware on the Supercharger network is limited to 400 volts. This means that vehicles with 800-volt charging capabilities will charge slower at Tesla V3 Supercharger stations compared to the most powerful CCS stations. However, the deployment of V4 Superchargers and the development of the Ionna fast-charging network, backed by eight automakers and expected to include both CCS and NACS connectors, are expected to address this issue in the future. Overall, the opening of the Supercharger network to non-Tesla electric vehicles marks a significant step towards greater interoperability and convenience for EV owners.
