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

95 INTRODUCTION
96 The increased use of renewable energy is enhancing the decarbonization of energy production
97 by reducing CO2 emissions caused by the use of fossil fuels. The production of renewable
98 energy with solar and wind power is however associated with large temporal output fluctuations.
99 This causes increased voltage and frequency instabilities in the power grid. These irregularities
100 can be advantageously counteracted with battery-based energy storage systems (BESS).
101 Such battery-based energy storage systems can be assembled with reuse batteries coming
102 from other electric energy storage installations or electric vehicles.
103 The reuse of batteries enhances all facets of the life cycle thinking (LCT) by reducing premature
104 product obsolescence.
105 Reuse cells, modules or battery assemblies require a particular attention toward the possible
106 impact on the environment they will have due to their state of being a pre-aged component.
107 The impacts to the environment resulting from reuse batteries are reviewed and appropriate
108 requirements are defined.
109 This document complements, when reuse batteries are involved, the information and guidance
110 provided by IEC TS 62933-4-1.
