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.
