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 61 427-2:201 5, 3.8, modified – admitted terms “battery management unit” and
“BMU” omitted, “battery” replaced by “flow battery energy system”, Notes 2 to 4 deleted.]
3.1.4 battery support system
BSS 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, power conversion system, or battery management system
Note 1 to entry: The battery support system is controlled by the battery management system.
<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).IEC 62932-1 pdf download.
