IEC/TC 21 - Secondary cells and batteries
To provide standards for all secondary cells and batteries related to product (dimension and performance), safety (including marking and labelling), testing, and safe application (installation, maintenance, operation) irrespective of type or application or configuration (hybrid, stand alone, module). Main applications are: • automotive (car, motorcycle, truck) for starting, lighting, ignition, start/stop • industrial (telecom, UPS, reliable power supply and traction) • electrical vehicles (full electrical vehicle, hybrid car, bicycle) • portable (computer, tool, lamp) • onboard batteries (aircraft, railway, ship, motor-home) • energy storage (renewable, on- grid and off-grid). All electrochemical systems are considered such as Lead acid, Nickel based (NiMH, NiCd) and Lithium based. New battery technologies and chemistries such as flow batteries and High temperature batteries (e.g. sodium sulfur, sodium nickel chloride) are included. The work is shared between TC 21 and SC 21A according to technologies and applications. For standardization of applications and system integration, TC 21 is cooperating with the responsible Committees, TC 9, TC 34, TC 69, TC 82, TC 105, TC 116, TC 120 and ISO TC22/SC21.

Préparer des normes pour toutes les cellules secondaires et les batteries liées au produit (dimension et performance), la sécurité (y compris le marquage et l'étiquetage), les tests et l'application sécurisée (installation, maintenance, fonctionnement) quel que soit le type, l'application ou la configuration (hybride, autonome , Module). Les principales applications portent sur: - L’automobile (voitures, 2 roues, camion) : démarrage, éclairage, allumage, démarrage / arrêt - Industriel (télécom, GPS, fiabilité d’alimentation, traction) - portable (ordinateur, outil, lampe) - batteries embarquées (avion, chemin de fer, navire, camping-car) - stockage d'énergie (renouvelable, sur réseau et hors réseau). Tous les systèmes électrochimiques sont compris tels acide au plomb, à base de nickel (NiMH, NiCd) et à base de lithium De nouvelles technologies de batteries et des produits chimiques tels que des batteries à courant et des batteries à haute température (par exemple soufre de sodium, chlorure de sodium et de nickel) sont inclus. Les travaux sont répartis entre le TC 21 et le SC 21A selon les technologies et les applications. Les coopérations suivantes sont établies avec les comités : TC 9, TC 34, TC 69, TC 82, TC 105, TC 116, TC 120 and ISO TC22/SC21

The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.
A Technical Committee (TC) in ISO is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
