Overview

HD 60364-5-57:2022/prAA:2025 is a European draft amendment to the standard for low-voltage electrical installations, focusing specifically on stationary secondary batteries. This document, developed by CENELEC (European Committee for Electrotechnical Standardization), supplements HD 60364-5-57 and addresses the selection and erection of electrical equipment involving stationary secondary batteries. The amendment ensures harmonization at the European level and provides clarity on installation, safety, and operational requirements for these battery systems.

The standard is essential for professionals involved in electrical installation design, safety compliance, and maintenance of low-voltage electricity supply systems across Europe.

Key Topics

• Modification to Technical Definitions: Refines the definition of “island mode” as scenarios where electrical installations remain energized despite disconnection from public supply.
• Operational Modes: Removal of specific subclauses related to battery operation modes, streamlining requirements.
• Battery Characteristics and Selection: Updates the section on the main characteristics of stationary secondary batteries, aligning these factors within broader equipment selection criteria.
• Short-Circuit Current Considerations: Clarifies the need to reference EN IEC 62485-2 for short-circuit management in systems with lead-acid, nickel-metal hydride (Ni-MH), or nickel-cadmium (Ni-Cd) batteries. Requirements for other technologies are under review.
• Hazard Protection: Expands the coverage on protecting against hazards such as fire and chemicals, in addition to traditional electrical hazards.
• Maintenance Practices: Emphasizes that only skilled or instructed persons should maintain battery installations, enhancing worker safety.
• Battery Accommodation: Standardizes terminology in guidance related to accommodation and accessibility of stationary secondary batteries.
• National Conditions and Deviations: Incorporates mechanisms for special national conditions and A-deviations, addressing specific requirements that differ across European countries.

Applications

This amendment is designed for various practical applications in the electrical sector:

• Design and Installation: Guides engineers and contractors in the proper selection and configuration of stationary batteries in low-voltage electrical installations, ensuring compliance with European regulations.
• Safety Compliance: Supports the development of safer environments by addressing risks associated with high-capacity batteries, including electric shock, fire, chemical hazards, and explosion risks.
• Facility Maintenance: Informs facilities managers and maintenance personnel on up-to-date procedures, underlining the necessity for skilled handling and periodic servicing by qualified individuals.
• Harmonization Across Europe: Assists multinational organizations and local authorities in aligning their electrical installation practices with European harmonized requirements, while accommodating regional or national differences.
• Reference for Industry: Serves as a key reference for manufacturers, inspectors, and standardization bodies when assessing, certifying, or innovating stationary battery systems in building and infrastructure projects.

Related Standards

• HD 60364 Series: Overarching European standards for the design and erection of low-voltage electrical installations, of which this document is a part.
• EN IEC 62485-2: Specifies safety requirements for the installation and operation of stationary batteries, referenced specifically for short-circuit current considerations in the amendment.
• National Standards: Each European country may have supplementary national regulations or practices incorporated through special national conditions or A-deviations as referenced in Annex ZA and Annex ZB.

Conclusion

HD 60364-5-57:2022/prAA:2025 is a critical amendment for professionals working with stationary secondary batteries in low-voltage electrical installations. By focusing on European harmonization, safety measures, and national specificities, it enhances both regulatory compliance and practical safety in electricity supply systems throughout Europe. This standard is an essential resource for ensuring robust design, safe operation, and efficient maintenance of stationary battery systems in diverse low-voltage applications.
