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.
A list of all parts in the IEC 62932 series, published under the general title Flow battery energy
systems for stationary applications, can be found on the IEC website.

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

• 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.]

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.]
