Tesla’s Supercharger network is now welcoming non-Tesla EVs, with Ford and Rivian leading the charge in early 2024. The transition marks a significant shift in EV charging infrastructure across the United States.
By December 2023, most major EV manufacturers had committed to Tesla’s charging standard. The Society of Automotive Engineers (SAE) formalized the North American Charging Standard (NACS) — Tesla’s charging port design — paving the way for broader adoption.
The 2025 Hyundai Ioniq 5 is among the first vehicles rolling off production lines with native NACS ports. Until more NACS-equipped models hit the market, most non-Tesla EVs need adapters to access Supercharger stations.
It’s not just about hardware. Automakers are releasing software updates to enable seamless integration with Tesla’s charging network. These updates allow vehicles to communicate with Superchargers for automatic payment processing and display station locations in navigation systems.
Tesla’s Magic Dock — available at many Supercharger locations — can sometimes eliminate the need for separate adapters.
Ford blazed the trail in February 2024, becoming the first to provide adapters to its customers. Rivian, General Motors, Volvo, Polestar, and Nissan have since joined the network.
Several other manufacturers are in line to gain access. Tesla indicates BMW, Genesis, Hyundai, JLR, Kia, Lucid, and Mercedes-Benz will connect to the network soon.
The transition isn’t without technical hurdles. Most of Tesla’s current V3 Superchargers operate at 400 volts, which means EVs designed for 800-volt charging — like some premium models from Porsche and Hyundai — won’t charge at their maximum potential speed.
Tesla’s newer V4 Superchargers will support full-speed charging for 800-volt vehicles. The upcoming Ionna network, backed by eight major automakers, plans to offer both CCS and NACS connectors — providing another solution for high-voltage charging needs.
Despite the voltage limitations at existing stations, the expanding Supercharger network significantly improves charging options for non-Tesla EV owners. The network’s reliability and widespread presence make it a valuable addition to the growing EV charging infrastructure.
Green Car Reports notes that while V4 hardware will accommodate higher-voltage vehicles, the current V3 infrastructure — which makes up most of North America’s Supercharger network — has some technical limitations.
