Secondary lithium-ion cells for the propulsion of electric road vehicles - Part 1: Performance testing

IEC 62660-1:2018 is available as IEC 62660-1:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62660-1:2018 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). This document specifies the test procedures to obtain the essential characteristics of lithium-ion 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. IEC 62660-1:2018 cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The purpose of each test has been added. b) The power test has been revised for clarification, and an informative part of the current-voltage characteristic test has been moved to the new Annex C.

Sekundarni litij-ionski členi za pogon električnih cestnih vozil - 1. del: Preskušanje zmogljivosti

Ta del standarda IEC 62660 določa preskušanje zmogljivosti in življenjske dobe sekundarnih litij-ionskih členov za pogon električnih vozil, vključno z električnimi akumulatorskimi vozili (BEV) in hibridnimi električnimi vozili (HEV).
OPOMBA 1: Sekundarni litij-ionski člen za pogon priključnega hibridnega električnega vozila (PHEV) je mogoče preskusiti s postopkom uporabe BEV ali uporabe HEV v skladu z zasnovo baterijskega sistema na podlagi dogovora med proizvajalcem členov in kupcem.
Ta dokument določa preskusne postopke za pridobitev osnovnih lastnosti litij-ionskih členov za pogon vozil v povezavi z zmogljivostjo, gostoto porazdelitve moči, gostoto porazdelitve energije, obdobjem skladiščenja in življenjsko dobo.
Ta dokument podaja standardne preskusne postopke in pogoje za preskušanje osnovnih lastnosti zmogljivosti litij-ionskih členov za pogon vozil, ki so nepogrešljive za zagotavljanje osnovne ravni zmogljivosti in pridobivanje osnovnih podatkov o členih za različne zasnove baterijskih sistemov ter akumulatorjev.
OPOMBA 2: Na podlagi dogovora med proizvajalcem člena in kupcem je mogoče poleg pogojev, določenih v tem dokumentu, izbrati posebne preskusne pogoje. Selektivni preskusni pogoji so opisani v dodatku A.
OPOMBA 3: Preskusi zmogljivosti električno povezanih litij-ionskih členov je mogoče opraviti s sklicevanjem na ta dokument.
OPOMBA 4: Specifikacija preskusa za litij-ionske akumulatorje in sisteme je opredeljena v standardu ISO 12405-4 [1].
