OLINK CCS2 to GBT 400A DC Adapter: Ushering in a new era of fast charging for Chinese electric vehicles overseas.

The global expansion of Chinese electric vehicles has accelerated dramatically in recent years. Brands such as BYD, MG, Zeekr, XPeng, GAC Aion and Leapmotor are no longer limited to the domestic market; they are gaining strong traction across Europe, the Middle East, Southeast Asia and Australia. This rapid growth brings new energy to local EV ecosystems, but it also reveals a practical challenge: most public DC chargers in these regions are built on the CCS2 standard, while the majority of Chinese EV models use the GB/T DC charging interface.

When a car and a charger cannot communicate, charging becomes impossible. For EV drivers, this results in inconvenience and range anxiety. For charging operators, it means idle chargers, reduced utilization, and missed revenue opportunities. As the number of Chinese EVs continues to rise globally, the demand for a high-power, reliable CCS2-to-GBT solution has shifted from optional to essential.

The newly released OLINK CCS2 to GBT V2 DC Adapter, supporting up to 400 amps and 400kW Max, is designed specifically to bridge this gap. It enables GB/T electric vehicles to charge efficiently on CCS2 fast-charging networks, making it one of the most advanced and commercially-ready solutions in the industry today.

A Commercial-Grade Adapter Engineered for Modern Fast-Charging Networks

The core of the new OLINK adapter is its ability to deliver a true 400A output, which is significantly higher than what typical adapters on the market can provide. Most competing products are limited to around 150 to 250 amps, a level insufficient for today’s 150kW to 360kW fast chargers. OLINK’s engineering team redesigned the internal electrical architecture with high-conductivity busbars, optimized thermal paths, and reinforced structural components to ensure stable charging even under long-duration high-current loads.

This improvement makes the adapter suitable for real commercial scenarios rather than occasional personal use. Charging operators can confidently deploy it on high-power chargers and expect consistent performance across different vehicle models.

Advanced Safety Architecture for Continuous High-Power Operation

Supporting 400A is not only a matter of electrical capability; safety must be built into every component of the system. The OLINK V2 design incorporates upgraded insulation barriers, enhanced heat dissipation, continuous temperature monitoring, electromagnetic shielding, strain relief protection, and reinforced connector structures. These improvements ensure that the adapter maintains a low temperature rise even in extended fast-charging sessions.

By improving core electrical and mechanical stability, the adapter can withstand the demanding conditions of commercial fast-charging environments, including repeated daily use, exposure to outdoor weather and long-term operational stress.

A Practical Solution That Immediately Improves Charging Station Utilization

For CPOs, the most compelling benefit of the OLINK adapters is the increase in revenue potential. Every charging station operator aims to maximize utilization, yet many existing CCS2 networks cannot serve the rapidly growing Chinese EV population. With this adapter, a station instantly becomes compatible with a wider range of vehicles without requiring any infrastructure upgrades.

The impact is immediate. More drivers can charge, more sessions are completed, and idle time is reduced. In markets where Chinese EVs already hold a significant share, a single adapter can translate into a meaningful improvement in overall charging throughput. This makes it a cost-effective tool for enhancing ROI without investing in new charger hardware or additional installation.

Effortless Operation with Plug-and-Charge Convenience

The OLINK CCS2 to GBT adapter is designed with simplicity in mind. There is no software setup and no protocol reconfiguration required. The adapter automatically bridges communication between CCS2 chargers and GB/T vehicles. When plugged in, both sides communicate seamlessly through the built-in control module, allowing the charging session to start just like a native CCS2 connection.

This ease of use benefits both EV drivers and service providers. Dealerships, fleet operators and car rental companies can include the adapter as part of their delivery package, ensuring drivers can immediately access public charging networks without additional learning or setup.

Broad Application Across Multiple Industries

The versatility of the adapter allows it to fit seamlessly into various real-world scenarios. Public charging networks can immediately expand their supported vehicle range. EV dealerships can relieve customer concerns about charging compatibility from day one. Fleet operators can simplify energy management by allowing all vehicles to use a unified charging network. Rental companies can minimize customer support issues while improving user satisfaction. Even commercial properties such as hotels, parking facilities and retail complexes can enhance the practicality of their existing charging infrastructure by making it accessible to Chinese EV owners.

How the Adapter Works Behind the Scenes

At the heart of the adapter is an intelligent communication system that translates between the CCS2 fast-charging protocols (DIN 70121 and ISO 15118) and the GB/T 27930 standard used by most Chinese EVs. This ensures that the vehicle’s battery management system and the charging station’s power module remain synchronized throughout the entire charging session.

Real-time monitoring of voltage, current, temperature and status feedback ensures that the charger delivers the correct power level at all times. The stability of this control process is essential for safety and efficiency, especially in high-power scenarios where fluctuations can affect both the charger and the vehicle.

Why OLINK Leads the Market in High-Performance CCS2-to-GBT Solutions

Compared with standard adapters on the market, OLINK’s 400A V2 model stands out with significantly higher power capacity, stronger thermal performance, more robust mechanical design and enhanced protocol compatibility. These characteristics make it suitable not only for personal EV owners but also for operators who require reliability and consistency in every charging session.

This level of engineering positions OLINK as a technology provider capable of meeting the global demand for high-power, cross-standard EV charging—an area that is becoming increasingly important as international EV adoption accelerates.
