As Chinese EV brands accelerate their global expansion, particularly into Europe and other CCS2-dominated regions, the need for reliable CCS2-to-GBT adapters has surged. Overseas charging infrastructures often differ from the GBT standard used in China, making cross-standard compatibility essential for both automakers and EV users.
To support this rapidly growing market demand, OLINK has launched an upgraded version of its CCS2-to-GBT adapter 400A, aligning with the industry’s move toward higher-power fast charging and improved interoperability. This upgrade underscores OLINK’s commitment to enabling seamless global charging for Chinese EVs and supporting the broader transition toward unified, high-efficiency charging ecosystems.
Higher Current Capacity: From 250A/300A to 300A/400A
The previous CCS2-GBT V1 supported selectable currents of 250A / 300A, meeting mainstream DC charging requirements.
The upgraded V2 boosts its selectable current to 300A / 400A, representing a significant leap in performance.
Benefits include:
- Higher peak charging power
- Shorter charging time and improved efficiency
- Full compatibility with next-generation high-voltage, high-rate fast-charging platforms
For charging operators or EV owners pursuing maximum efficiency, this upgrade offers clear advantages.
Newly Added Dust Cover: Stronger Connector Protection
The V2 introduces an integrated flip-style dust cover on the CCS2 base unit to effectively block dust and debris.
Advantages:
- Prevents foreign matter from entering the connector
- Reduces the risk of poor contact over long-term use
- Minimizes maintenance needs
- Extends product lifespan
- Offers better outdoor protection compared to V1, which lacked this feature
Enhanced Ergonomics: New Carrying Handle for Better Grip and Convenience
While V1 offered a compact form, it lacked a dedicated grip point, making insertion and removal less convenient.
The V2 features a completely redesigned ergonomic structure:
Dedicated Large Carrying Handle
Provides better leverage for plugging and unplugging, especially when frequently moving the adapter.
More Comfortable Grip Profile
A more rounded and refined housing enhances the handling experience and reduces the likelihood of accidental damage due to improper operation.
Internal Hardware Improvements: Supporting Higher Current with Greater Stability
Compared to V1, the V2 integrates multiple internal upgrades:
- Upgraded CCS2 base unit
Improves conductivity and heat dissipation for stable high-current operation. - Enhanced internal protection
Ensures safer, more reliable performance under demanding conditions.
Better Compatibility With Complex Charging Ports
The V2 has been optimized to support more EV models with varying charging port structures, including vehicles from brands such as Zeekr and Avatr.
Insertion accuracy and fit quality are significantly improved.
Upgrade Summary: Key Advantages of CCS2-GBT V2
| Feature | V1 | V2 (Upgraded) |
| Selectable Current | 250A / 300A | 300A / 400A |
| Handling | No handle | New ergonomic handle |
| Dust Protection | None | Integrated dust cover |
| Base Unit | Standard | Upgraded CCS2 module |
| Protection | Standard | Enhanced overall protection |
| Ease of Use | Moderate | Significantly improved |
Conclusion
The CCS2-GBT Adapter upgrade goes far beyond increasing current capacity. It delivers comprehensive enhancements in performance, durability, user experience, and structural protection, making the V2 a future-ready solution for both EV owners and charging operators.
