What is gbt charger?

The GB/T charging standard is a set of GB/T standards, primarily in the GB/T 20234 family, for electric vehicle AC and DC fast charging used in China.

The GB/T charging standard is a set of GB/T standards, primarily in the GB/T 20234 family, for electric vehicle AC and DC fast charging used in China. The standards were revised and updated most recently in 2015 by the Standardization Administration of China. The term is an abbreviation of 国标推荐 (guóbiāo/tuījiàn), translated as "recommended/voluntary national standard".

The GB/T charging standards are comparable to similar standards from the Society of Automotive Engineers (SAE), the International Electrotechnical Commission (IEC), and the International Standards Organization (ISO) which provide general, physical, and signaling requirements for electric vehicle charging interfaces.

GB/T 18487 provides general requirements for conductive charging systems, corresponding to IEC 61851.

GB/T 20234 provides physical requirements for connectors and interfaces, corresponding to IEC 62196 and SAE J1772.

GB/T 27930 provides communication requirements, corresponding to ISO 15118 and SAE J1772.

The five referenced GB/T standards were revised and released on December 28, 2015:

GB/T 18487.1-2015 Conducting Charging Systems for Electric Vehicles – Part 1: General Requirements

GB/T 20234.1-2015 Connectors for Conducting Charging for Electric Vehicles – Part 1: General Requirements

GB/T 20234.2-2015 Connectors for Conducting Charging for Electric Vehicles – Part 2: Alternating Current Charging Interfaces

GB/T 20234.3-2015 Connectors for Conducting Charging for Electric Vehicles – Part 3: Direct Current Charging Interfaces

GB/T 27930-2015 Communication Protocol between Off-board Conductive Charger and Battery Management System of Electric Vehicle.
