Tiêu chuẩn quốc gia TCVN 14296-6:2025 (IEC 62196-6:2022)

The rapid global expansion of electric vehicles (EVs) underscores the critical need for robust, safe, and interoperable charging infrastructure. In this evolving landscape, national and international standards play a pivotal role in ensuring the compatibility and reliability of charging components. This document, TCVN 14296-6:2025, addresses these crucial requirements by focusing on dimensional compatibility for DC pin and contact-tube vehicle couplers. It specifically targets components designed for DC EV supply equipment where protection relies on electrical separation, providing essential guidelines for manufacturers and engineers to develop safe and efficient electric vehicle charging solutions.

Manufacturers of electric vehicle charging equipment, design engineers, regulatory bodies, and testing laboratories in the field of electromobility.

TCVN 14296-6:2025 (IEC 62196-6:2022) establishes the specific dimensional compatibility requirements for plugs, socket-outlets, vehicle connectors, and vehicle inlets used in conductive DC charging of electric vehicles. This part of the standard is essential for ensuring that DC pin and contact-tube vehicle couplers for DC EV supply equipment, particularly those with protection relying on electrical separation, can interoperate safely and effectively. The standard meticulously outlines various aspects, supplementing or replacing general provisions from TCVN 14296-1:2025. Key areas covered include the detailed characteristic parameters such as rated voltage (up to 120 V DC) and current (up to 100 A), alongside a comprehensive overview of the DC interface, specifying contact configurations for power delivery and communication (e.g., CAN, CPW for charge control). A significant focus is placed on precise dimensions to guarantee physical interchangeability and correct mating between charging components. Furthermore, the standard addresses critical safety elements like protection against electric shock, detailing the required sequencing of contacts during insertion and withdrawal to prevent hazardous arcs. It also specifies stringent requirements for interlock mechanisms to secure connections, ensures the mechanical strength of cable assemblies, and mandates the ageing resistance of materials. By standardizing these physical and operational attributes, TCVN 14296-6:2025 significantly contributes to the safety, reliability, and widespread adoption of DC fast charging infrastructure, fostering greater confidence and convenience for electric vehicle users.
