1 Scope This part of IEC 62932 relates to flow battery energy systems (FBES) used in electrical energy storage (EES) applications and provides the main terminology and general aspects of this technology, including terms necessary for the definition of unit parameters, test methods, safety and environmental issues. 2 Normative references There are no normative references in this document. 3 Terms, definitions and abbreviated terms Terms and definitions 3.1 For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp
3.1.1 ambient temperature environmental temperature around a flow battery energy system 3.1.2 auxiliary energy energy consumed by all the auxiliary equipment and components of a flow battery and of a flow battery energy system Note 1 to entry: The equipment and components include, but are not limited to, battery management system, battery support system, fluid circulation system. 3.1.3 battery management system BMS electronic system associated with a flow battery energy system which monitors and/or manages its state, calculates secondary data, reports that data and/or controls its environment to influence the flow battery energy system’s performance and/or service life Note 1 to entry: The function of the battery management system can be fully or partially assigned to the battery pack and/or to equipment that uses flow battery energy store systems. [SOURCE: IEC 61427-2:2015, 3.8, modified – admitted terms “battery management unit” and “BMU” omitted, “battery” replaced by “flow battery energy system”, Notes 2 to 4 deleted.]
3.1.46 rated energy manufacturer declared value of the energy content of the FBES system when discharged under specified (rated) conditions and measured at the primary POC Note 1 to entry: (J) is the base unit, other units may be chosen for convenience as well (kWh, MWh). 3.1.47 rated input power manufacturer declared value of input power for a specific set of operating conditions of the FBS/FBES Note 1 to entry: The rated input power is expressed in watts (W). 3.1.48 rated maximum power manufactuer declared highest power level that the FBS/FBES can accept or deliver 3.1.49 rated output power manufacturer declared value of output power for a specific set of operating conditions of the FBS/FBES 3.1.50 routine test conformity test made on each individual item during or after manufacture [SOURCE: IEC 60050-151:2001, 151-16-17] 3.1.51 sampling test test on a sample [SOURCE: IEC 60050-151:2001, 151-16-20] 3.1.52 sensor <of a measurement element> device which detects or measures a physical property and records, indicates or responds to it 3.1.53 service life duration from the time of the FBES system commissioning test to the end of service life Note 1 to entry: The term “commissioning test” is defined in IEC 60050-411:1996, 411-53-06. 3.1.54 short-circuit current maximum current which should be delivered by a flow battery system or flow battery energy system into an external circuit with zero electric resistance, or an external circuit which depresses the cell or battery voltage to approximately zero volt Note 1 to entry: Zero electric resistance is a hypothetical condition and in practice the short-circuit current is the peak current following in a circuit of very low resistance compared to the internal resistance of the battery. [SOURCE: IEC 60050-482:2004, 482-03-26, modified – “(related to cells or batteries)” omitted from term, and “cell or battery” replaced by “flow battery system or flow battery energy system” in the definition.]
3.1.5 charge charging <of a battery> operation during which a secondary cell or battery is supplied with electric energy from an external circuit which results in chemical changes within the cell and thus the storage of energy as chemical energy Note 1 to entry: A charge operation is defined by its maximum voltage, current, duration and other conditions as specified by the manufacturer. [SOURCE: IEC 60050-482:2004, 482-05-27, modified – term “charging of a battery” separated into “charge” and “charging” with “of a battery” as the domain, and addition of the note.] 3.1.6 cold standby standby state requiring warm up before a demand to operate can be met Note 1 to entry: A cold standby state may apply to redundant or stand-alone items. Note 2 to entry: In this context “warm up” includes meeting any conditions required to operate as required (e.g. achieving the required temperature, speed, pressure). [SOURCE: IEC 60050-192:2015, 192-02-11, modified – “state” omitted from the term, and the domain, “of an item”, deleted.]
