Understanding charging standards is the first step to selling globally. Different regions use different connectors, voltage/current requirements, and certifications — get the standard wrong, and your product cannot enter the market. As of 2026, the global standard landscape is clear: CCS2 is the dominant export standard, NACS unifies North America, GB/T serves China, CHAdeMO is being phased out, and ChaoJi is emerging as the next-generation high-power standard.
1. Global Standard Landscape
Figure 1: Global DC Charging Standard Market Share, 2026
The global standard landscape is actually quite straightforward:
• GB/T: China national standard, used exclusively in mainland China — ~33% of global DC charger share (due to China's large domestic market)
• CCS2: The dominant export standard, covering Europe, Australia, Southeast Asia, Middle East, Latin America, Africa — ~28% share
• NACS: The new North American standard (formerly Tesla connector), rapidly replacing CCS1 — ~20% global share
• CCS1: Legacy North American standard, being phased out — ~12% installed base
• CHAdeMO: Japanese standard, declining — ~7% share, mostly legacy vehicles
2. DC Fast Charging Standards Detailed Comparison
Figure 2: Maximum Power Comparison by DC Charging Standard
1. CCS2 (Combined Charging System Type 2)
• Regions: Europe, UK, Australia, NZ, Southeast Asia, Middle East, Latin America, Africa, India — the most universal export standard
• Connector: Adds two DC pins to the Type 2 AC connector, combined AC/DC port
• Specs: Up to 1000V, 500A, theoretical 500kW; 350kW commercially deployed with liquid-cooled cables
• Outlook: Will remain the dominant global export standard, evolving to MCS (Megawatt Charging System) for heavy-duty vehicles
CCS2 is the first standard any global exporter must support.
2. NACS (North American Charging Standard / SAE J3400)
• Regions: United States, Canada, Mexico — unified North American standard
• Connector: Compact Tesla-developed design using shared pins for AC and DC, significantly smaller than CCS
• Specs: Up to 1000V, 400A, theoretical 400kW
• Current status: As of early 2026, NACS represents 48% of North American DC fast charging connectors, with CCS1 at 40%
• Outlook: 75%+ of new North American EVs will have NACS in 2026; CCS1 will be largely phased out by 2027

3. GB/T 27930 (China National Standard)
• Regions: Mainland China
• Connector: Separate AC and DC ports; DC uses a 9-pin round connector
• Specs: Up to 1000V, 250A, max 250kW
• Outlook: Domestic China market only; export products generally do not need GB/T unless specifically requested. The next-generation ChaoJi standard (joint China-Japan development) supports up to 600kW but has minimal commercial deployment.
4. CCS1 (Combined Charging System Type 1)
• Regions: Legacy North American and some Korean vehicles
• Specs: Up to 500V, 200A, max 200kW
• Outlook: Replaced by NACS; new North American EVs no longer use CCS1. New chargers do not need native CCS1 — adapters are sufficient for legacy vehicles.
5. CHAdeMO
• Regions: Japan, primarily legacy Nissan Leaf vehicles
• Specs: Most chargers 50-100kW
• Outlook: Japan itself is shifting to CCS2 and ChaoJi; CHAdeMO is being phased out globally.
3. AC Charging Standards
AC charging standards are simpler:
• Type 2 (IEC 62196): AC standard for almost all markets outside North America/Japan; single/three-phase up to 43kW
• Type 1 (SAE J1772): North America/Japan AC standard; single-phase up to 19.2kW
• NACS AC: New North American standard, shared AC/DC connector
• GB/T AC: China domestic AC standard, primarily 7kW
For exported wallbox EV chargers, Type 2 covers 80%+ of global markets; NACS is needed for North America.
4. Recommendations for Exporters
Practical guidance for EV charger manufacturers:
1. Global DC fast chargers: Prioritize CCS2 with modular NACS capability; other standards via connector swap or adapter — most cost-effective approach
2. Europe/Middle East/SEA/LATAM/Australia: CCS2 is sufficient
3. North America: NACS required; CCS1 as optional compatibility
4. Multi-standard units: For borders, ports, international fleets; support CCS2+NACS+GB/T but at higher cost
5. Residential wallboxes: Type 2 for global markets, NACS for North America
Note that standards are just the foundation — different markets require different certifications (CE/UL/UKCA/RCM/INMETRO). Professional EV charger manufacturers can provide multi-standard customization to meet diverse market requirements for complete EV charging solutions.
