Lead-acid starter batteries - Part 6: Batteries for micro-cycle applications
This document is applicable to lead-acid batteries with a nominal voltage of 12 V, used primarily as power source for the starting of internal combustion engines (ICE), lighting and also for auxiliary equipment of ICE vehicles. These batteries are commonly called “starter batteries”. Batteries with a nominal voltage of 6 V are also included in the scope of this document. All referenced voltages need to be divided by two for 6 V batteries. The batteries under the scope of this document are used for micro-cycle applications in vehicles which can also be called Start-Stop (or Stop-Start, idling-stop system, micro-hybrid or idle-stop-and-go) applications. In cars with this special capability, the internal combustion engine is switched off during a complete vehicle stop, during idling with low speed or during idling without the need of supporting the vehicle movement by the internal combustion engine. During the phases in which the engine is switched off, most of the electric and electronic components of the car need to be supplied by the battery without support of the alternator. In addition, in most cases an additional regenerative braking (recuperation or regeneration of braking energy) function is installed. The batteries under these applications are stressed in a completely different way compared to classical starter batteries. Aside of these additional properties, those batteries need to crank the ICE and support the lighting and also auxiliary functions in a standard operating mode with support of the alternator when the internal combustion engine is switched on. All batteries under this scope need to fulfil basic functions, which are tested under application of EN 50342-1:2015. This document is applicable to batteries for the following purposes: — Lead-acid batteries of the dimensions according to EN 50342-2 for vehicles with the capability to automatically switch off the ICE during vehicle operation either in standstill or moving (“Start-Stop”); — Lead-acid batteries of the dimensions according to EN 50342-2 for vehicles with Start-Stop applications with the capability to recover braking energy or energy from other sources. This document is not applicable to batteries for purposes other than mentioned above, but it is applicable to EFB delivered in dry-charged conditions according to EN 50342-1:2015, Clause 7. NOTE The applicability of this document also for batteries according to EN 50342-4 is under consideration.
Blei-Akkumulatoren-Starterbatterien - Teil 6 : Batterien für Mikrozyklen-Anwendungen
Batteries d'accumulateurs de démarrage au plomb - Partie 6: Batteries pour applications micro-cycles
Le présent document s’applique aux batteries d’accumulateurs au plomb d’une tension nominale de 12 V utilisées principalement comme sources d’alimentation pour le démarrage des moteurs à combustion interne, ainsi que pour l’éclairage et les installations auxiliaires des véhicules équipés de moteur à combustion interne. En langage courant, ce type de batteries d’accumulateurs est appelé "batterie de démarrage". Les batteries d’une tension nominale de 6 V relèvent également du domaine d’application du présent document. Pour les batteries de 6 V, il est nécessaire de diviser par deux toutes les tensions spécifiées. Les batteries relevant du domaine d’application du présent document sont utilisées sur des véhicules "microhybridés" intégrant un système de type Start-Stop et/ou un système de récupération d’énergie dans lesquels la batterie est soumise à des sollicitations de type "microcyclage". Sur ces automobiles possédant cette capacité particulière, le moteur à combustion interne est coupé à l’arrêt complet du véhicule, au ralenti à faible vitesse ou au ralenti lorsqu’il n’est pas nécessaire que le moteur à combustion interne assure le déplacement du véhicule. Lors des phases au cours desquelles le moteur est coupé, il est nécessaire que la plupart des composants électriques et électroniques de l’automobile soient alimentés par la batterie sans le soutien de l’alternateur. De plus, dans la plupart des cas, une fonction supplémentaire de freinage par récupération (récupération ou régénération de l’énergie de freinage) est installée. Dans ces applications, les batteries sont soumises à des contraintes tout à fait différentes de celles qui s’exercent sur les batteries de démarrage de type classique. Outre ces propriétés supplémentaires, il est nécessaire que ces batteries assurent le démarrage du moteur à combustion interne et l’éclairage, ainsi que les fonctions auxiliaires associées à un mode de fonctionnement normal, avec le soutien de l’alternateur quand le moteur à combustion interne est en marche. Il est nécessaire que toutes les batteries relevant de ce domaine d’application assurent des fonctions de base qui sont soumises à essai en application de l’EN 50342-1:2015. Le présent document s’applique aux batteries destinées aux applications suivantes: — batteries au plomb de dimensions conformes à l’EN 50342-2 pour les véhicules capables de couper automatiquement le moteur à combustion interne pendant le fonctionnement du véhicule, qu’il soit immobile ou en mouvement ("Start-Stop"); — batteries au plomb de dimensions conformes à l’EN 50342-2 pour les véhicules destinés aux applications Start-Stop et capables de récupérer l’énergie de freinage ou l’énergie provenant d’autres sources. Le présent document ne s’applique pas aux batteries destinées à des applications autres que celles mentionnées ci-dessus, mais s’applique aux batteries chargées liquides améliorées (EFB, Enhanced Flooded Battery) livrées en chargé sec, conformément à l’Article 7 de l’EN 503421:2015. NOTE La possibilité que le présent document s’applique aussi aux batteries conformes à l’EN 50342-4 est à l’étude.
