GB/T charging
GB/T 20234 (AC and DC variants)
China’s domestic charging standard. AC and DC versions are physically different. The DC variant scales above 250 kW and is being upgraded to the ChaoJi/GB/T 2.0 family co-developed with CHAdeMO.

GB/T: China's Standard for Electric Vehicle Charging
GB/T is China's national standard for electric vehicle charging equipment. It encompasses both AC and DC charging, though the connectors differ physically. This standard dictates how EVs communicate with charging stations, ensuring interoperability within China.
Standardization and Variants
The GB/T standard, formally GB/T 20234, was developed to create a unified charging infrastructure within China. It exists in two primary forms: AC and DC. While both use the GB/T designation, the AC connector is distinct from the DC connector. Early DC versions supported peak power up to 250 kW. However, the standard is evolving.
Where You'll Find It
GB/T connectors are overwhelmingly found in Mainland China. Major charging networks across the country utilize this standard. If you are charging an EV in China, you will encounter GB/T ports on most vehicles and charging stations.
Power Levels and Generational Differences
While the standard supports up to 250 kW, the actual power delivered can vary based on the vehicle's onboard charging capability and the charging station's output. Newer EVs and infrastructure are pushing these limits. The DC variant is being upgraded as part of the ChaoJi/GB/T 2.0 initiative, a collaboration with CHAdeMO, aiming for higher power delivery and enhanced features.
Adapters and Compatibility
For vehicles not equipped with a native GB/T port, adapters are required. These allow EVs with other connector types (like CCS or CHAdeMO) to use GB/T infrastructure. However, the availability and reliability of such adapters can vary. Ensure any adapter you use is certified and compatible with your vehicle.
- What is the main difference between GB/T AC and DC connectors?
- The key difference is physical design and intended use. The GB/T AC connector is typically used for slower charging, similar to Level 1 or Level 2 charging in other regions. The GB/T DC connector is designed for high-power, rapid charging. Although both fall under the GB/T 20234 standard, they are not interchangeable without adapters and serve different charging speed needs.
- Can I use a GB/T charger with my car if it has a different charging port?
- Yes, but you will need an adapter. If your car has a CCS or CHAdeMO port and you are in a region with GB/T chargers, you can use a specialized adapter. Conversely, if your car has a GB/T port and you are elsewhere, you'd need a GB/T to CCS or CHAdeMO adapter. Always ensure the adapter is correctly rated and compatible with both your car and the charging station.
- What is the maximum charging speed with a GB/T connector?
- The official peak power for commercial GB/T DC charging is rated at 250 kW. However, the standard is evolving with the ChaoJi/GB/T 2.0 upgrade, which aims to support significantly higher power levels. The actual speed you experience will depend on your vehicle's maximum charging rate and the specific charger's output.
- Is GB/T charging common outside of Mainland China?
- No, GB/T is primarily the domestic standard for Mainland China. While some limited adoption or testing might occur in other regions, you will overwhelmingly find GB/T connectors and charging infrastructure within China. For charging elsewhere, you are more likely to encounter standards like CCS, CHAdeMO, or Type 2.
- What is the future of the GB/T standard?
- The GB/T standard is actively being developed. A major upgrade is underway with the ChaoJi/GB/T 2.0 family, co-developed with CHAdeMO. This next generation aims to increase charging speeds substantially, improve bidirectional charging capabilities, and enhance overall communication protocols between the vehicle and the charging infrastructure, preparing for the next wave of EV technology.
