- Tesla is opening its Supercharger network to non-Teslas
- Ford and Rivian were the first non-Teslas to connect
- The opening of the Supercharger network has been an ongoing ramp-up and is not a one-size-fits-all situation
By the end of 2024, almost all of the major EV brands in the US have signed on to provide Tesla Supercharger access, and finally accept the automaker's NACS port for future EVs. But the rollout proceeded at a different pace for each product.
Owners of EVs come from many non-Tesla brands you must use an adapter connecting with Supercharger stations until the widespread release of new cars with NACS ports, a process that just started with the 2025 Hyundai Ioniq 5 is helped by the formalization of NACS as a de facto standard by SAE in late 2023.
Ford EVs at Tesla Supercharger
Most automakers are also pushing software updates that allow their EVs to properly connect to Supercharger stations plug-and-charge operationand updates that allow Supercharger stations to appear in vehicle routing and payment applications.
As the first announcements to switch to a Tesla charging port, Ford is leading the way in providing adapters to allow customers to charge faster at Supercharger stations. That started in February 2024, with other automakers following later in the year and a few now confirmed for the first half of 2025. Here is where things stand now.
Automakers with Supercharger access:
Ford
Rivian
General Motors
Volvo
Polestar
Nissan
Automakers say they're getting Supercharger access “soon,” according to Tesla:
BMW
Genesis
Hyundai
JLR
Kia
Lucid
Mercedes-Benz
As Green Car Reports previously stated, the Tesla V4 hardware will likely be able to handle electric vehicles power 800 volts at full price. But Tesla's V3 hardware—most of the North American hardware available on the Supercharger network at this time—is limited to 400 volts, or maybe a little higher.
That creates a problem for car manufacturers who already sell 800-volt cars, as those cars it will charge slowly at Tesla V3 Supercharger stations than they would at more powerful CCS stations. But the more widespread deployment of the V4 Supercharger will help solve that, along with the creation of the Ionna's fast-charging network supported by eight automakers that are expected to include both CCS and NACS connectors.
