Flow Batteries

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.

Standard covers recommended information for an objective evaluation of emerging energy storage technology by a potential user of any stationary application. Storage technologies are those that provide a means for the reversible storage of electrical energy (i.e., device receives electrical energy and can discharge electrical energy later). The storage medium may be electrochemical (e.g., batteries), kinetic (e.g., flywheels), electrostatic (e.g., electric double-layer capacitors [EDLCs]), thermal or other medium.

The document provides alternative approaches and practices for design, operation, maintenance, integration and interoperability, including distributed resources interconnection, of stationary or mobile battery energy storage systems (BESS) with the EPS at customer facilities, electricity distribution facilities or bulk transmission electricity facilities.

NFPA 400 consolidates fundamental safeguards for the storage, use, and handling of hazardous materials in all occupancies and facilities. The Code does not apply to storage or use of hazardous materials for individual use on the premises of one- and two-family dwellings.

The CWA provides guidance on the specification, installation and operation of flow batteries. It facilitates the pre-commercial phase when flow batteries need to be compared with other flow batteries or other electrical storage devices. It provides guidance to conformity assessment bodes to benchmark flow battery conformity with existing directives and other regulations.

Safety standard for stationary batteries for energy storage applications, non-chemistry specific and includes electrochemical capacitor systems or hybrid electrochemical capacitor and battery systems. Includes requirements for unique technologies such as flow batteries and sodium beta (i.e., sodium sulfur and sodium nickel chloride). Includes construction requirements, tests and production tests. Also includes requirements for cells used in these systems such as lithium-ion, nickel, Lead-Acid and includes sodium beta and flow battery requirements.

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
