Join us as we embark on a detailed journey to discover which electric vehicles are GBT-compatible and what that means for the future of electrified transportation.
GBT Charging Interface and Connector Types
The GBT (Guobiao Standard) Charging Interface and Connector Types are part of a Chinese national standard for electric vehicle (EV) charging systems. These standards were developed to streamline the various connector options available on the market, ensuring that all EVs can connect to the charging stations across the country. The most common of these standards are the GB/T 20234 and GB/T 18487, which include requirements for conductive charging system of electric vehicles, including the shape of the connectors, their electrical properties, and communication protocols between the vehicle and the charger.
The GBT interface for AC charging typically features connectors with a type-1 based design called “Yazaki”, suitable for single-phase charging, while the GB/T 20234.2 specifies a three-phase charging connection for faster charging speeds. On the other hand, for DC charging, the GBT standard deploys a “GB/T” connector, which can handle higher currents and therefore offers a fast charging option.
Compatibility with the GBT standard varies across electric vehicles, especially between domestic Chinese vehicles and international models. The GBT standard is primarily compatible with electric vehicles designed and manufactured for the Chinese market. Many domestic Chinese automotive manufacturers equip their EV models with GBT-compliant connectors by default to ensure they are compatible with the extensive public and private charging infrastructure within China.
However, as the adoption of EVs becomes more widespread internationally, there have been movements towards adopting common charging standards to ensure interoperability. Currently, electric vehicles manufactured for the international market, especially those from European and American brands, use different standards such as Combined Charging System (CCS), CHAdeMO, or Tesla’s proprietary Supercharger standard.
Despite these differences, there have been efforts to create adapters and multi-standard chargers that can cater to various connector types, including GBT. Therefore, some global models may be capable of using GBT standard charging points through these means, although this is not as seamless as having a native GBT-compatible connector.
To drive the adoption of green transportation solutions across vehicle categories, the GBT standard does not only apply to passenger electric cars. It has also been extended to cover a wide range of electric vehicles including buses, commercial vehicles, two-wheelers, and light EVs. However, compatibility and adoption levels can vary significantly depending on the market and the specific segment of electric vehicles in question. For electric buses and commercial vehicles, the adoption of the GBT standard is more widely seen in the Chinese market, where these types of vehicles have a clear preference for native charging standards. In contrast, electric two-wheelers and light EVs might exhibit a mix of adherence to GBT or other charging standards, depending on the manufacturer’s target market and international ambitions.
Compatible Electric Car Models with GBT Standard
The Guobiao (GB/T) standards are Chinese national standards promulgated by various governmental bodies, including the Standardization Administration of the People’s Republic of China. For electric vehicles (EVs), the GB/T standards refer to the technical specifications for charging interfaces and are an essential consideration for EV manufacturers, particularly those operating in or exporting to the Chinese market.
When talking about compatible electric car models with the GB/T standard, this primarily refers to EVs that can interface with the Chinese charging infrastructure as designed per these standards.

Major Chinese EV manufacturers such as BYD, NIO, BAIC, SAIC, and Geely all produce a range of electric car models that comply with the GB/T charging standard. These companies are pivotal in China’s EV market and have developed numerous models that support this standard, including both all-electric and plug-in hybrid electric vehicles.
The GB/T standard covers both AC and DC charging protocols. For DC fast charging, it includes specifications for a high voltage and high current capacity, which speeds up the charging process considerably compared to AC charging. It is important to note that the compatibility of an EV with the GB/T standard is critical in China, where infrastructure has been developed according to these local standards, and international standards such as CCS (Combined Charging System) or CHAdeMO may not be as widely supported.
As the Chinese EV market continues to grow and as Chinese manufacturers expand internationally, the presence of the GB/T standard outside of China could become more significant. Adapters are available which allow vehicles equipped with GB/T connectors to use charging stations with different standards. This could be particularly relevant for consumers in regions where Chinese EVs are being imported. These adaptations may help in increasing the interoperability between different charging standards, thus making it easier for EV drivers to charge their vehicles in various locations globally.
Electric vehicles compatible with the GB/T standard typically include those geared towards the consumer market, such as sedans, SUVs, and compact cars. For instance, models like the BYD Qin, e-Series, and Tang, or NIO’s range of electric SUVs, and sedans are all designed to support GB/T charging infrastructure. The standard is also applied in larger commercial vehicles, though the question focuses on passenger cars.
In summary, the GB/T standard is a crucial framework for charging electric vehicles in China, which has created an environment where domestic car manufacturers can thrive by producing compatible models. As the influence of Chinese EVs grows in global markets, understanding and interoperability of the GB/T standard will be an important consideration for global EV adoption.
