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).

The objective of this standard is to specify 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 standard 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.
