Electrically propelled mopeds and motorcycles - Test specifications and safety requirements for lithium-ion battery systems (ISO/DIS 18243:2024)

ISO 18243:2017 specifies the test procedures for lithium-ion battery packs and systems used in electrically propelled mopeds and motorcycles.
The specified test procedures enable the user of this document to determine the essential characteristics on performance, safety and reliability of lithium-ion battery packs and systems. The user is also supported to compare the test results achieved for different battery packs or systems.
ISO 18243:2017 enables setting up a dedicated test plan for an individual battery pack or system subject to an agreement between customer and supplier. If required, the relevant test procedures and/or test conditions of lithium-ion battery packs and systems are selected from the standard tests provided in this document to configure a dedicated test plan.
NOTE 1 Electrically power-assisted cycles (EPAC) cannot be considered as mopeds. The definition of electrically power-assisted cycles can differ from country to country. An example of definition can be found in the EU Directive 2002/24/EC.
NOTE 2 Testing on cell level is specified in IEC 62660 (all parts).

Cyclomoteurs et motocycles à propulsion électrique - Spécifications d'essai et exigences de sécurité pour les systèmes de batterie au lithium-ion (ISO/DIS 18243:2024)

ISO 18243:2017 spécifie des modes opératoires d'essai spécifiques pour les blocs et systèmes de batterie au lithium-ion utilisables dans les motocycles et cyclomoteurs à propulsion électrique.
Les modes opératoires d'essai spécifiés permettent à l'utilisateur du présent document de déterminer les caractéristiques essentielles de performance, de sécurité et de fiabilité des blocs et systèmes de batterie au lithium-ion. L'utilisateur peut également comparer les résultats d'essai obtenus pour différents blocs ou systèmes de batterie.
ISO 18243:2017 permet d'établir un plan d'essai dédié pour un bloc ou système de batterie individuel sous réserve d'un accord entre le client et le fournisseur. Si nécessaire, les modes opératoires et/ou conditions d'essai approprié(e)s des blocs et systèmes de batterie au lithium-ion sont choisis parmi les essais normalisés fournis dans le présent document pour configurer un plan d'essai dédié.
NOTE 1 Le vélo à assistance électrique (VAE) ne peut pas être considéré comme un cyclomoteur. La définition du vélo à assistance électrique peut différer selon les pays. Un exemple de définition est indiqué dans la Directive 2002/24/CE de l'UE.
NOTE 2 Des essais de performance des accumulateurs sont spécifiés dans l'IEC 62660 (toutes les parties).
