FLOW BATTERY ENERGY SYSTEMS FOR STATIONARY APPLICATIONS –
Part 1: Terminology and general aspects
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62932-1 has been prepared by IEC technical committee 21:

Secondary cells and batteries, in collaboration with IEC technical committee 105: Fuel cell

technologies.
The text of this International Standard is based on the following documents:
FDIS Report on voting
21/1027/FDIS 21/1037/RVD

Full information on the voting for the approval of this International Standard can be found in the

report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be

• withdrawn,
• replaced by a revised edition, or
• amended.

3.1 Terms and definitions
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.]

3.1.4
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.

3.1.5
charge
charging

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.]
