As global electric vehicle adoption accelerates, the lack of a unified charging standard continues to create problems for charging operators, car fleets, and EV manufacturers. Europe primarily uses CCS2, while China and parts of Asia still rely heavily on the GBT DC fast-charging standard.
This mismatch becomes more noticeable with the rise of:
- 800V high-voltage EV platforms
- Ultra-fast DC charging (250–480 kW)
- Cross-border EV usage
- Mixed-model charging stations
The OLINK CCS2–GBT Fixed DC Charging Adapter is engineered specifically to solve this compatibility challenge. Supporting 1000VDC and 250–400A, this device allows CCS2 DC chargers to directly charge GBT electric vehicles—without replacing the entire charger.
For charging operators, this means a higher utilization rate, lower CAPEX, and future-proof compatibility.

Both CCS2 and GBT EVs exist.
This adapter becomes essential for universal compatibility.
Automotive Manufacturers & Testing Facilities
For R&D labs and vehicle testing centers, supporting both CCS2 and GBT is crucial.
This adapter allows engineers to test multi-standard EVs using a single charging platform.
Comparison — Fixed Adapter vs. Portable Adapter vs. Installing a New GBT Charger
| Feature | Fixed Adapter | Portable Adapter | New GBT Charger |
|---|---|---|---|
| Max Current | Up to 400A | 80–200A | 250–400A |
| Durability | Very High | Low | High |
| Installation Cost | Low | None | Very High |
| Suitable for CPOs | Yes | No | Yes |
| Safety | Highest | Medium | High |
Summary:
For commercial charging, fixed adapters are the best balance of high power, safety, and affordability.
Why This Product Matters in 2026
Several trends make this product extremely valuable in the coming years:
- EVs are moving toward 800V ultra-fast-charging platforms
- Global operators seek lower CAPEX charging expansion
- International vehicle circulation is increasing
- GBT vehicles remain in large volumes globally
- EV charging standards are unlikely to unify soon
Therefore, a universal high-power CCS2→GBT adapter is a necessary bridge for the next 5–10 years.
