CCS vs NACS vs CHAdeMO: EV Connector Guide

The EV charging connector landscape is consolidating around two standards: CCS and NACS. Here's what you need to know about each connector type and which one your vehicle uses.

CCS (Combined Charging System)

The most common DC fast charging connector in North America (non-Tesla). Used by Ford, GM, BMW, Hyundai, Kia, VW, and most other manufacturers. Supports up to 350 kW. Combines a J1772 AC plug with DC fast charging pins.

NACS (North American Charging Standard)

Originally Tesla's proprietary connector, now adopted as SAE J3400. Starting 2025, Ford, GM, Rivian, and most manufacturers are switching to NACS. Smaller and lighter than CCS. All Tesla Superchargers use NACS.

CHAdeMO

Japanese standard used by older Nissan Leaf and Mitsubishi Outlander PHEV. Being phased out in North America. Nissan's newer Ariya uses CCS. Few new stations are adding CHAdeMO connectors.

Adapters

CCS-to-NACS and NACS-to-CCS adapters are available from Tesla and third parties. Tesla includes a J1772 adapter for Level 2 charging. CHAdeMO-to-CCS adapters do not exist due to protocol differences.
