Type 1, Type 2, GB/T, and CCS Plug Standards Explained
As electric vehicles expand globally, charging plug standards remain one of the most confusing aspects of EV infrastructure. Different regions, grid systems, and vehicle designs have led to multiple connector standards—each optimized for specific markets and use cases.
For EV charger manufacturers, operators, and commercial buyers, understanding Type 1, Type 2, GB/T, and CCS standards is essential for building compatible, scalable charging solutions.

Why Multiple EV Plug Standards Exist
Unlike traditional fuel nozzles, EV charging connectors evolved regionally due to:
- Differences in electrical grids (single-phase vs three-phase)
- Local safety regulations
- Early market leaders and automaker preferences
- AC and DC charging architecture divergence
As a result, no single global plug standard dominates all markets.
Overview of Major EV Charging Plug Standards
Quick Reference Comparison
| Plug Standard | Charging Type | Typical Power | Primary Regions |
| Type 1 (SAE J1772) | AC | Up to 7.4 kW | North America, Japan |
| Type 2 (IEC 62196) | AC | Up to 22 kW | Europe, UK, many global markets |
| GB/T | AC & DC | AC up to 22 kW | China |
| CCS (Combo) | DC (and AC*) | 50–350 kW | Europe, North America |
*CCS uses Type 1 or Type 2 for AC charging depending on region.
Type 1 (SAE J1772): Single-Phase AC Standard
Key Characteristics
- Single-phase AC only
- Max current: typically 32A
- Common power: 3.7–7.4 kW
Typical Use Cases
- Residential charging
- Workplace and light commercial charging
- Markets with single-phase residential grids
Limitations
- No native three-phase support
- Lower maximum AC power compared to Type 2
Type 1 is reliable and simple, but less scalable for commercial installations.
Type 2 (IEC 62196): The Global AC Workhorse
Key Characteristics
- Supports single-phase and three-phase AC
- Power range: 7 kW / 11 kW / 22 kW
- Mandatory standard across the EU
Advantages
- Higher charging power with three-phase supply
- Compact and secure design
- Ideal for public, commercial, and destination charging
Type 2 has become the dominant AC charging standard worldwide, outside North America and China.
GB/T: China’s National Charging Standard
Key Characteristics
- Separate connectors for AC and DC
- AC power up to 22 kW
- Fully defined under Chinese national regulations
Market Role
- Mandatory in mainland China
- Not directly compatible with Type 1 or Type 2
- Requires adapters for cross-standard use
GB/T reflects China’s independent EV ecosystem and large-scale domestic market.
CCS (Combined Charging System): DC Fast Charging Standard
| CCS Variant | Based On | Primary Region |
| CCS1 | Type 1 | North America |
| CCS2 | Type 2 | Europe & others |
Key Characteristics
- Combines AC and DC in one vehicle inlet
- DC charging up to 350 kW
- Designed for highway and rapid charging
CCS dominates DC fast charging, but relies on Type 1 or Type 2 for AC charging.
AC vs DC Plug Standards: Practical Implications
| Aspect | AC Standards (Type 1 / Type 2 / GB/T AC) | DC Standards (CCS / GB/T DC) |
| Typical Charging Time | Hours | Minutes |
| Infrastructure Cost | Low | High |
| Grid Impact | Manageable | Significant |
| Best Use Case | Home & destination | Highway & fleet turnaround |
For most daily charging needs, AC plug standards remain the backbone of EV infrastructure.
Choosing the Right Plug Standard for Your Market
When selecting EV chargers, decision-makers should consider:
- Target vehicle market (EU / US / China)
- Grid availability (single-phase vs three-phase)
- Installation environment (home, hotel, fleet, public)
- Long-term scalability and compliance
Incorrect plug selection can limit charger utilization and future compatibility.
