NACS Becomes the Standard EV Connector
In a remarkably swift industry shift, Tesla's North American Charging Standard (NACS) has been adopted by virtually every major automaker and charging network operating in North America. This consolidation around a single connector ends years of incompatibility headaches.
What Happened
In late 2022, Tesla opened its connector specification as an open standard. By mid-2024, every major automaker — Ford, GM, Rivian, Hyundai, BMW, Mercedes, Volkswagen, Toyota, Honda, and others — announced adoption of NACS for future vehicles.
In November 2023, SAE International standardized NACS as SAE J3400, giving it formal industry backing alongside (and effectively replacing) CCS1 as the dominant connector in North America.
What Changed for Drivers
New Vehicles (2025+)
Most new EVs sold in North America from 2025 onward come with a NACS port natively. This means:
- Direct access to Tesla Supercharger network (16,000+ locations, 55,000+ stalls in North America)
- One connector type at new and retrofitted public chargers
- No adapters needed for the majority of charging sessions
Existing CCS Vehicles
If you have a 2024 or earlier EV with a CCS1 port:
- Free NACS-to-CCS adapters are being provided by many automakers (Ford, GM, Rivian, etc.)
- Adapters work at Superchargers that have been upgraded for non-Tesla authentication
- Some older Supercharger stalls may not yet support third-party vehicles
Charging Network Upgrades
Major networks are adding NACS cables:
- Tesla Supercharger: Now accepting non-Tesla vehicles at most U.S. locations via the Tesla app
- Electrify America: Adding NACS cables alongside existing CCS
- ChargePoint: New stations include NACS; retrofits underway
- EVgo: Dual-cable (NACS + CCS) at new installations
Technical Comparison
| Feature | NACS (J3400) | CCS1 | |---------|:-:|:-:| | Size | Smaller, lighter | Larger, heavier | | Max DC power | 1 MW+ | 350 kW (typical) | | Max AC power | 19.2 kW | 19.2 kW | | Pin count | 5 | 9 | | Locking | Magnetic / push-button | Mechanical latch | | Liquid cooling | Supported | Supported |
NACS is physically smaller and simpler while supporting equal or greater power throughput. The smaller connector is easier to handle, particularly appreciated in cold weather with gloves.
What This Means for Home Charging
For home Level 2 charging, the connector change is straightforward:
- New NACS vehicles: Use a J1772-to-NACS adapter (usually included with the car) for existing J1772 home chargers, or purchase a NACS home charger
- Tesla Wall Connector: Already NACS-native; works with any NACS vehicle
- Existing J1772 chargers: Continue to work with all vehicles using the included adapter
Timeline
- 2025: Most new EVs ship with NACS ports
- 2026: CCS-only public chargers becoming uncommon at new installations
- 2027–2028: CCS likely phased out at most new charging locations
- Long-term: NACS/J3400 becomes the only connector needed in North America (similar to how Type 2/CCS2 standardized in Europe)
The standardization is a significant positive for EV adoption — removing one of the confusing friction points that deterred potential buyers.
