WG 6 - TC 21/SC 21A/WG 6

IEC 63369-1:2026 addresses general requirements and methodology, whereas intended IEC 63369-2 and intended IEC 63369-3 address applications of the methodology and default values of the CFF parameters by geographic area (see Annex B).
This document provides a comprehensive methodology for the calculation of carbon footprint of industrial type Li-ion battery systems from cradle to grave.
Second life and/or usage that was not intended when the battery was put on the market is not taken into account in this document.
This document, along with the other parts of this series, does not apply to batteries for portable, SLI and electric road vehicle traction applications. The definition of the parameters used for the carbon footprint calculation allows for comparability of results for all rechargeable Li-ion chemistries.
Classes of representative products are defined in this document to allow comparison inside each class.
This methodology, based on the data provided by the battery manufacturer, is mainly intended to allow a carbon footprint assessment of several battery solutions over the Cumulated Requested Service (CRS). This assessment can be used in the selection process of the battery purchaser.
The methodology can also be used for a variety of purposes such as battery system development, eco-design and participation in voluntary or mandatory programs.
The methodology in this document is based exclusively on attributional life cycle assessment (LCA).
The carbon footprint calculation of charging equipment and power conversion equipment not necessary for battery functions is not covered in this document.

IEC 63218:2021 provides requirements and recommendations on environmental aspects of secondary lithium, nickel cadmium and nickel-metal hydride cells and batteries for portable applications (hereafter referred to as “relevant secondary cells and batteries”).
Relevant secondary cells and batteries are specified within the scopes of IEC 61960-3, IEC 61960-4, IEC 61951-1, and IEC 61951-2.
NOTE Portable applications are defined in IEC 61960-3 as comprising hand-held equipment, transportable equipment, and movable equipment. See IEC 61960-3 for examples.
This document is not intended to be applied to batteries embedded in end-use products. Once the embedded battery is removed from an end-use product, this document becomes applicable to it.
The safety and control circuits as well as cases associated with relevant secondary batteries, except for those forming part of an end-use product, are covered by this document as parts of the relevant secondary batteries.
