IEC 60050-631:2024

Overview

IEC 60050-631:2024 is the latest edition of the International Electrotechnical Vocabulary (IEV) focused on Electrical Energy Storage Systems. Published by the International Electrotechnical Commission (IEC), this standard establishes a comprehensive and consistent terminology framework specific to electrical energy storage technologies. It serves as a horizontal publication, designed for use by technical committees preparing IEC publications in alignment with IEC Guide 108.

This standard provides a unified vocabulary related to general principles, specific applications, and associated technologies of electrical energy storage systems (EESS). By harmonizing terminologies, IEC 60050-631:2024 supports global understanding and cooperation within the energy storage sector, enhancing communication and documentation quality for experts, engineers, manufacturers, and regulatory bodies.

Key Topics

• Classification of electrical energy storage systems, detailing types and categories to standardize descriptions.
• Specifications including technical parameters, performance criteria, and system attributes essential for design and evaluation.
• Planning and Installation terminology addressing system integration, site requirements, architecture, and connection types (e.g., one-point and two-point connection systems).
• Operation aspects, such as charging/discharging cycles, operational modes, and power capability considerations that affect system performance.
• Safety and Environmental Issues covering terms related to risk management, safety protocols, and environmental impacts associated with energy storage technologies.

Additional features include detailed illustrations and charts like the charging/discharging cycle example and power capability diagrams to support clear understanding of system functions.

Applications

The terminology defined in IEC 60050-631:2024 is critical for a wide array of practical applications within the electrical energy storage domain:
