The GB/T standard covers both AC and DC charging, with each type having a dedicated connector design. The AC GB/T connector is typically used for slower, overnight charging and provides up to 7,4 kW, suitable for residential and lower-demand public charging stations. Meanwhile, the GB/T DC connector enables much faster charging, with power levels up to 237,5 kW on high-capacity models. This capability supports rapid recharging, meeting the needs of EV drivers across China’s vast network of public fast chargers, including urban areas and highway corridors. In contrast to Western markets where dual-standard systems like CCS are prevalent, China’s adoption of GB/T ensures uniformity across its EV infrastructure.
Another defining feature of the GB/T standard is its communication protocol, which establishes a seamless connection between EVs and charging stations. This protocol enables real-time monitoring of charging parameters such as current, voltage, and temperature, enhancing the safety and reliability of the charging process. Because GB/T is regulated by Chinese authorities, it is designed to support large-scale implementation across China’s rapidly growing EV market, where government-driven investments in charging infrastructure have contributed significantly to the expansion of EV adoption.
The GB/T standard is instrumental in shaping China’s EV industry by fostering compatibility across a diverse range of EV brands and charger manufacturers. This standardisation has made China one of the most EV-friendly countries globally, with widespread charging accessibility. As China continues to lead in EV production and usage, the GB/T standard not only supports its domestic infrastructure but is also influencing EV policies and technology across Asia and other emerging markets.
