IEC 60364-5-57:2022

Overview

IEC 60364-5-57:2022 is an international standard published by the International Electrotechnical Commission (IEC) that specifies key requirements and recommendations for the selection, erection, and safe installation of stationary secondary batteries in low-voltage electrical installations. Stationary secondary batteries refer to rechargeable batteries used as prime energy storage mediums for backup power or other stationary applications. This standard focuses on the design, correct use, and protection measures necessary for these battery installations.

Importantly, IEC 60364-5-57:2022 does not cover the design or testing of battery products themselves, nor whole system designs that include batteries, which are addressed in separate IEC standards.

Key Topics

• Scope and Application
  The standard applies specifically to secondary stationary batteries within low-voltage electrical installations, outlining safety and performance requirements for their erection and use.

• Operation Modes
  It details operation scenarios such as grid-connected mode and islanding mode, crucial for applications where batteries support or isolate from the electrical grid.

• Characteristics of Stationary Secondary Batteries
  Includes guidance on battery types, selection criteria, and integration with electrical converters to optimize performance and safety.

• Protection Measures
  Addresses comprehensive safety considerations including:

  • Protection against electric shock
  • Thermal effect prevention to avoid overheating
  • Protection against short-circuits
  • Effective isolation methods
  • Countermeasures for unexpected islanding events
  • Additional safeguards against miscellaneous hazards associated with battery installations

• Battery Accommodation
  Instructions for battery room design to ensure safe housing, including ventilation, separation zones, and warning labels.

• Technical Appendices
  Informative annexes provide detailed technical data such as discharge characteristics, internal impedance, gas evolution phenomena, and effects of load on battery behavior.

Applications

IEC 60364-5-57:2022 serves as a critical reference for engineers, designers, and electrical installation professionals involved in:

• Installing stationary backup power systems using lead-acid, nickel-cadmium, or other rechargeable battery technologies
• Designing emergency power supplies in commercial or industrial environments
• Implementing energy storage solutions that interface with electrical grids, including microgrids and islanded systems
• Ensuring compliance with international safety standards to mitigate risks related to electric shock, fire, and environmental hazards in battery rooms
• Supporting prosumers and low-voltage installations that incorporate battery energy storage for reliability and resilience
