Standard (Draft)

This part of the standard specifies general safety requirements for stationary energy storages with lithium batteries. The purpose of the requirements of this standard is to ensure that HAZARDS to the operator/user and the surrounding area are reduced to a tolerable level. Requirements for protection against particular types of HAZARDS: electric shock or burn, mechanical hazards, spread of fire from the equipment, excessive temperature, effects of fluids and fluid pressure, liberated gases, explosion, chemical hazards (e.g., electrolyte).

This part of the IEC 62932 series specifies general information relating to the requirements and typical methods of test for flow battery system.

A flow battery is an electrolyte cyclical form battery, and a rechargeable battery mainly applicable to broad applications such as energy storage, independent power supply, grid stabilization, and a stabilization use of renewable energy. This standard is applicable to all flow battery systems.

The scope of this NWIP is to prepare normative documents on safety dealing with: 1) main risks related to couples of use cases and associated technologies; 2) technical contents and results to be included in the safety report and auditing framework; 3) list of main features to be validated by testing; 4) scale at which the storage system must be tested; and 5) recommendations to prevent or mitigate accidental effect.

Scope – Clear definition of what is/is not covered by the standard (e.g., power, voltage, other criteria).

The standard establishes minimum requirements for the application of the process of commissioning buildings and systems, and criteria for code officials (authority having jurisdiction [AHJ]), owners, and agencies to implement the commissioning requirements.

This standard and standard 62133-2 below are in development and are categorized in: Aerospace electric equipment and systems, Electrical and electronic equipment. These standards address safety of the respective battery chemistries for portable applications.

This International Standard relates to Flow Batteries used in Electrical Energy Storage (EES) applications and provides the main terminology and general aspects of this technology
