Attention is drawn to the possibility that some of the elements of this standard may be the subject of patent rights. The issuing body of this document shall not be held responsible for identifying any or all such patent rights. This standard was proposed by the Ministry of Industry and Information Technology of the People's Republic of China. This standard is under the jurisdiction of the National Technical Committee of Auto Standardization (SAC/TC 114).   Introduction GB/T 38775 aims to establish the requirements, test methods, interoperability and other requirements of electric vehicle wireless power transfer, and is planned to be composed of nine parts: ——Part 1: General requirements. This part specifies the overall requirements of the electric vehicle wireless power transfer. ——Part 2: Communication protocols between on-board charger and wireless power transfer device. This part specifies the communication protocol used to realize wireless charging control between communication service unit (CSU) and in-vehicle unit (IVU) of electric vehicle wireless power transfer, and the communication protocol for wireless charging control and management system (WCCMS) to participate in wireless charging control. ——Part 3: Specific requirements.

This part specifies the test method for communication consistency of the off-board device under test. ——Part 9: Communication consistency testing — Vehicle side. This part specifies the test method for communication consistency of the on-board device under test. Relying on electromagnetic field, the electric vehicle wireless power transfer transmits electric energy and actively emits electromagnetic energy outward, which possibly causes strong electromagnetic disturbance and potentially affects radio services and power supply network. Meanwhile, the electric vehicle wireless power transfer is likely to be interfered by various electromagnetic phenomena in the environment during operation, which will lead to charging failure and safety risks. The limits of electromagnetic disturbance, immunity requirements and corresponding test methods of the electric vehicle wireless power transfers are given in this document, which may promote the good control of the electromagnetic environment and ensure the function and safety of the wireless power transfer. Electromagnetic compatibility requirements and test methods of electric vehicles under other operating status have been specified in relevant standards. See GB/T 18387 (150kHz ~30MHz) and GB 34660 (30MHz~1GHz) for radiated disturbance in driving status, GB 34660 for radiated immunity in driving status, and GB/T 40428 Electromagnetic compatibility requirements and test methods of conductive charging for electric vehicles for disturbance and immunity in conductive charging status.
