Is Tesla’s GM (and other OEM) deal good for electric vehicles?

Yes. Allowing GM, Ford and others to use Tesla’s Supercharger network helps EV adoption by giving more drivers access to reliable long-distance charging.

Is this “very bad” for other charging networks?

It increases competition, but it does not eliminate other networks. ChargePoint, EVgo and Electrify America are adding NACS cables, allowing them to serve both CCS and NACS vehicles.

• Tesla’s network as the reliability benchmark.
• Retail and workplace chargers for convenience.
• Utility and city-operated stations in public areas.

What communication protocol do Tesla chargers use?

• AC (home & destination): PWM control-pilot similar to J1772/IEC 61851.
• DC fast charging: Tesla’s legacy CAN-based signaling; new NACS supports CCS-style PLC protocols (ISO 15118).
• Europe: Fully CCS2 compliant.

How can non-Tesla EVs use Tesla chargers?

• Magic Dock Superchargers (built-in CCS adapter).
• NACS-to-CCS adapters offered by automakers starting 2024–2025.
• Tesla-to-J1772 adapters for AC Wall Connectors.

Why J1772/CCS1/NACS in the U.S. and Type 2/CCS2 in Europe?

• Different grid systems (single-phase vs three-phase).
• Regulatory mandates in the EU favor Type 2/CCS2.
• Historical first-mover choices.
