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 flowbattery energy system
Note 1 to entry: The equipment and components indclude，but are not limited to, battery management system， batterysupport system. fluid circulation system.
3.1.3
battery management systemBMS
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 toinfluence the flow battery energy system’s performance and/or service life
Note 1 to entry: The function of the battery management system can be flly or partally assigned to the batterypack 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.J
3.1.4
battery support systemBss
auxiliary units, such as heat exchanger, ventilation system, safety system, and inert gas system,
used in an FBES, and which are not stacks，or part of the fluid circulation system， powerconversion system, or battery management system
Note 1 to entry: The battery support system is controlled by the battery management system.3.1.5
chargecharging
operation during which a secondary cell or battery is supplied with electric energyfrom an external circuit which results in chemical changes within the cell and thus the storageof energy as chemical energy
Note 1 to entry. A charge operation is defined by its maximum voltage,current,duration and other conditions asspecified by the manufacturer.
[sOURCE: IEC 60050-482:2004,482-05-27, modified – term “charging of a battery” separatedinto “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 ‘wam 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 thedomain, “of an item”, deleted.]
3.1.7
dischargedischarging
operation during which a secondary battery supplies electric energy to anexternal circuit which results in chemical changes within the cell and the release of energy as
electrical energy
Note 1 to entry.: A discharge operation is defined by its maximum voltage，current,duration and other conditions asspecified by the manufacturer.
3.1.8
emergency shutdown
rapid regulated shutdown of the flow battery energy system triggered by a protection system orby manual intervention
[SOURCE: IEC 60050-415:1999,415-01-11, modified – the word “regulated” added, and “windturbine” replaced by “flow battery energy system””.]
