NARI-TECH(SH:600406) Zhong Guo Neng Yuan Wang·2026-02-27 08:03Core Viewpoint - The release of the international standard IEC TS 62196-7:2026 for electric vehicle conductive charging vehicle adapters marks a significant step in establishing a globally compatible charging technology ecosystem, led by China's ChaoJi charging technology [1][4]. Group 1: Standard Overview - IEC TS 62196-7 focuses on the core technical specifications for direct current charging vehicle adapters, defining safety, interoperability requirements, and supporting testing methods [3]. - The standard specifies technical indicators with a rated voltage of up to 1500V DC, primarily applicable to adapters connecting vehicles with IEC 62196-3 standard plugs and sockets [3]. Group 2: Compatibility and Impact - The standard addresses the compatibility challenges between the ChaoJi interface and existing mainstream charging standards, facilitating the use of ChaoJi-equipped electric vehicles with the current extensive direct current charging network [4]. - The successful release of this standard highlights the technical expertise and international influence of the State Grid Electric Power Research Institute (NARI Group), which aims to contribute to global charging interface compatibility solutions [4]. Group 3: Future Developments - Ongoing discussions by IEC TC69 MT5 and PT17 working groups on supporting System D requirements and multi-system compatibility will complement IEC TS 62196-7, forming a complete technical system compatible with major global charging standards [4]. - The State Grid Electric Power Research Institute plans to continue its efforts in standardization within the charging interface sector, actively participating in the design and construction of global charging standards [4].
