Understanding CCS1, CCS2, NACS, and GB/T: Why Multi-Standard EV Charging Solutions Are the Future

Why Multi-Standard Compatibility Matters

The EV charging ecosystem is evolving rapidly, and no single standard dominates the global market. North America, Europe, China, and Japan all follow different regulations, and automakers are gradually adopting or transitioning between standards.

For B2B customers such as EV fleet operators, road rescue services, energy providers, and construction projects, having charging solutions that support multiple standards means:

• Higher compatibility: One device can serve different EV brands and regions.

• Lower operational risk: Avoid costly downtime caused by incompatible connectors.

• Better ROI: Maximize usage of each unit across diverse customer groups.

A Breakdown of the Four Major EV Charging Standards

CCS1 vs. CCS2

• CCS1 is widely used in North America (based on SAE J1772).

• CCS2 dominates Europe and is expanding globally (based on IEC 62196).

• CCS2 supports three-phase AC in addition to DC fast charging, making it more suitable for public and commercial networks.

• Both CCS1 and CCS2 deliver high-power DC fast charging, but infrastructure adoption differs by region.

NACS (North American Charging Standard)

• Originally developed by Tesla, NACS features a compact connector design and is backed by Tesla’s extensive Supercharger network.

• In 2023–2024, major automakers including Ford, GM, Mercedes, and Hyundai announced support for NACS, accelerating its position as the emerging default in North America.

• Charging providers are increasingly adding NACS to their stations, creating a dual CCS/NACS environment.

GB/T (China Standard)

• GB/T is China’s official national standard for both AC and DC charging.

• It dominates the world’s largest EV market, with tens of millions of charging sessions daily.

• Known for its high-power DC capabilities, GB/T sets the benchmark for large-scale government-driven charging deployments.

The Global Trend: Convergence and Coexistence

While NACS is gaining traction in North America, CCS2 remains the European benchmark, and GB/T dominates China. Rather than one global winner, the industry is heading toward coexistence of multiple standards.

This creates both opportunities and challenges:

• Opportunities: Businesses that provide flexible charging solutions can serve multiple markets and customer types.

• Challenges: Operators that rely on single-standard equipment may lose market share in regions with mixed EV adoption.
