41 Part 4-3: The protection requirements of BESS according to the environmental
42 conditions
45 FOREWORD
46 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
47 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
48 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
49 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
50 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
51 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
52 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
53 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
54 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
55 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
56 consensus of opinion on the relevant subjects since each technical committee has representation from all
57 interested IEC National Committees.
58 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
59 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
60 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
61 misinterpretation by any end user.
62 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
63 transparently to the maximum extent possible in their national and regional publications. Any divergence between
64 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
65 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
66 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
67 services carried out by independent certification bodies.
68 6) All users should ensure that they have the latest edition of this publication.
69 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
70 members of its technical committees and IEC National Committees for any personal injury, property damage or
71 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
72 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
73 Publications.
74 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
75 indispensable for the correct application of this publication.
76 9) [IEC/IEC and ISO] [draws/draw] attention to the possibility that the implementation of this document may involve
77 the use of (a) patent(s). [IEC/IEC and ISO] [takes/take] no position concerning the evidence, validity or
78 applicability of any claimed patent rights in respect thereof. As of the date of publication of this document,
79 [IEC/IEC and ISO] [had/had not] received notice of (a) patent(s), which may be required to implement this
80 document. However, implementers are cautioned that this may not represent the latest information, which may
81 be obtained from the patent database available at https://patents.iec.ch [and/or] www.iso.org/patents. [IEC/IEC
82 and ISO] shall not be held responsible for identifying any or all such patent rights.
83 IEC 62933-4-3 has been prepared by subcommittee WG4: of IEC technical committee TC120:
84 Electrical Energy Storage (EES) systems. It is an International Standard.
85 The text of this International Standard is based on the following documents:

90 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
91 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement available
92 at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
93 described in greater detail at www.iec.ch/publications.
94 The committee has decided that the contents of this document will remain unchanged until the
95 stability date indicated on the IEC website under webstore.iec.ch in the data related to the
96 specific document. At this date, the document will be

102 INTRODUCTION
103 According to the reports over the world, BESS has been influenced by the environmental
104 conditions and the climatic conditions of the areas where it is installed. Particularly the BESS
105 can be affected by temperature, humidity, and vibration and natural disasters. In order to
106 minimize the impacts, this document is expected to be of great help in stable installation and
107 operation by presenting the causes, risk factors and the appropriate measures for each
108 environmental condition when installing the BESS

111 Part 4-3: The protection requirements of BESS according to the
112 environmental conditions
116 1 Scope
117 This part of IEC 62933 applies to the effects of the environmental conditions on Battery Energy
118 Storage Systems (BESS). This document addresses these effects and identifies causes, chain
119 of events and final effects on the BESS. Based on those effects, preventative or mitigating
120 measures are described. Typical environmental effects on the BESS include, but are not limited
121 to, the effects of lightning, seismic activities, water, air, flora, fauna, and humans. The described
122 measures focus as a guideline on the entire BESS including all power and communication
123 connections and its Point of Connections (POCs).
124 The scope of this document is limited to BESS specific requirements and operating conditions.
125 Specific design or safety requirements of individual BESS subsystems are excluded from this
126 document
