CSA Preface 

This is the second edition of CSA E62660-1, Secondary lithium-ion cells for the propulsion of electric road vehicles - Part 1: Performance testing , which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 62660-1 (second edition, 2018-12). It supersedes the previous edition, published in 2015 as CAN/CSA-E62660-1 (adopted IEC 62660-1:2010). It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. This Standard is intended to be used in conjunction with CSA E62660-2:21, Secondary lithium-ion cells for the propulsion of electric road vehicles - Part 2: Reliability and abuse testing (adopted IEC 62660-2:2018, with Canadian deviations). 

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This part of IEC 62660 specifies performance and life testing of secondary lithium-ion cells used for propulsion of electric vehicles including battery electric vehicles (BEV) and hybrid electric vehicles (HEV). 

NOTE 1 Secondary lithium-ion cell used for propulsion of plug-in hybrid electric vehicle (PHEV) can be tested by the procedure either for BEV application or HEV application, according to the battery system design, based on the agreement between the cell manufacturer and the customer. This document specifies the test procedures to obtain the essential characteristics of lithiumion cells for vehicle propulsion applications regarding capacity, power density, energy density, storage life and cycle life. This document provides the standard test procedures and conditions for testing basic performance characteristics of lithium-ion cells for vehicle propulsion applications, which are indispensable for securing a basic level of performance and obtaining essential data on cells for various designs of battery systems and battery packs. 

NOTE 2 Based on the agreement between the cell manufacturer and the customer, specific test conditions can be selected in addition to the conditions specified in this document. Selective test conditions are described in Annex A. NOTE 3 The performance tests for the electrically connected lithium-ion cells can be performed with reference to this document. NOTE 4 The test specification for lithium-ion battery packs and systems is defined in ISO 12405-4 [1].
