Description

This International Standard is applicable to performance and endurance tests for secondary batteries used for vehicle propulsion applications. Its objective is to specify certain essential characteristics of cells, batteries, monoblocks, modules and battery systems used for propulsion of electric road vehicles, including hybrid electric vehicles, together with the relevant test methods for their specification.

The tests may be used specifically to test batteries developed for use in vehicles such as passenger vehicles, motor cycles, commercial vehicles, etc. This standard is not applicable to battery systems for specialist vehicles such as public transport vehicles, refuse collection vehicles or heavy duty vehicles, where the battery is used in the similar way to the industrial vehicles.

The test procedures are defined as a function of the vehicle requirements of performance.

This standard is applicable to lead-acid batteries, Ni/Cd batteries, Ni/MH batteries and sodium based batteries used in electric road vehicles.

Annex A specifies performance and cycle life test procedures of Ni/MH batteries used for the propulsion of hybrid electric vehicle (HEV).

NOTE This standard is not applicable to lithium-ion batteries for automobile application that are specified in IEC 62660-1, IEC 62660-2, ISO 12405-1 and ISO 12405-2 (to be published).
