Specifications

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.

This guidance provides for the protection of stationary battery systems, which include the battery and DC components to and including the first protective device downstream of battery terminals. Recommendations are not intended to set requirements; rather, they present options to the battery system designer concerning the types of protection available.

The ISO 9000 family addresses various aspects of quality management and contains some of ISO’s best known standards. The standards provide guidance and tools for companies and organizations who want to ensure that their products and services consistently meet customer’s requirements, and that quality is consistently improved.

Readiness of emergency power is a key consideration in safeguarding building occupants in the event of a disruption of the normal utility supply. NFPA 111 covers performance requirements for stored electric energy systems providing an alternate source of electrical power in buildings and facilities during interruption of the normal power source.

NFPA 791 covers recommended procedures for evaluating unlabeled electrical equipment for compliance with nationally recognized standards. Criteria provide guidance to third-party field evaluation bodies (FEBs) on how to perform evaluations of unlabeled electrical equipment in a consistent and reliable manner, thus assisting regulating authorities who make product and related installation approval decisions and facilitating acceptance of the results. Specific areas covered include pre-site preparation, construction inspection, electrical testing, and reporting, and documentation.

1.1 These requirements cover fixed and location-dedicated electric room heating equipment rated 600 V or less to be employed in ordinary locations in accordance with the NEC, ANSI/NFPA 70. 1.2 These requirements do not cover movable heaters, wall- or ceiling-hung heaters, baseboard heaters, duct heaters, central-heating furnaces, fan-coil units, panel- or cable-type radiant-heating equipment, electric boilers, or any other electric heating equipment or appliances covered in or as a part of separate, individual requirements.

These requirements cover ESS that are intended to store energy from power or other sources and provide electrical or other types of energy to loads or power conversion equipment. The ESS may include equipment for charging, discharging, control, protection, communication, controlling the system environment, fuel or other fluid movement and containment, etc. The system may contain other ancillary equipment related to the functioning of the energy storage system.
