  • Une batterie d'accumulateurs ou plus communément une batterie, est un ensemble d'accumulateurs électriques reliés entre eux de façon à créer un générateur électrique de tension et de capacité désirée. Ces accumulateurs sont parfois appelés éléments de la batterie ou cellule.On appelle aussi batteries les accumulateurs rechargeables destinées aux appareils électriques et électroniques domestiques.
  • Pilha elétrica, célula galvânica, pilha galvânica ou ainda pilha voltaica é um dispositivo que utiliza reações de óxido-redução para converter energia química em energia elétrica. A reação química utilizada será sempre espontânea.Neste dispositivo, têm-se dois eletrodos que são constituídos geralmente de metais diferentes, que fornecem a superfície na qual ocorrem as reações de oxidação e redução. Estes eletrodos são postos em dois compartimentos separados, imersos por sua vez em um meio contendo íons em concentrações conhecidas e separados por uma placa ou membrana porosa, podendo ser composta por argila não-vitrificada, porcelana ou outros materiais. As duas metades desta célula eletroquímica são chamadas de compartimentos e têm por finalidade separar os dois reagentes participantes da reação de óxido-redução, do contrário, os elétrons seriam transferidos diretamente do agente redutor para o agente oxidante. Finalmente, os dois eletrodos são conectados por um circuito elétrico, localizado fora da célula, denominado circuito externo, garantindo o fluxo de elétrons entre os eletrodos.As pilhas não devem ser confundidas com as baterias. Enquanto a primeira apenas converte energia química a elétrica, a segunda faz a interconversão entre energia química e elétrica.É importante saber que na pilha, os elétrons fluem do ânodo para o cátodo, sendo que o sentido da corrente elétrica, frequentemente utilizado na Física, se dá do cátodo para o ânodo.
  • Als Akkupack wird ein zusammengeschaltetes Paket mehrerer Akkumulatorzellen bezeichnet, welches zur praktischen Verwendung durch eine Umhüllung oder ein Gehäuse zusammengehalten und oft auch vor äußeren Einflüssen geschützt wird. Akkupacks sind entnehmbar bzw. austauschbar gestaltet und verfügen über lösbare elektrische Kontakte, oft durch Steckverbinder.Die verwendeten Zellen sollten dabei alle zum gleichen Typ eines Herstellers gehören, also eine möglichst identische Spannung, Kapazität und Belastbarkeit aufweisen. Innerhalb eines Akkupacks können auch Blöcke aus mehreren Zellen parallel geschaltet sein, und mehrere solcher Zellblöcke wiederum in Reihe.
  • Een accupack is een samenstelling van meerdere oplaadbare batterijen. Accupacks worden onder andere in de modelbouw gebruikt, waar ze de energie voor elektromotoren leveren. De afzonderlijke cellen van een accupack worden meestal met krimpfolie bij elkaar gehouden, maar kunnen ook met plakband of lijm aan elkaar vastgemaakt zijn. Vaak zijn ze in een kunststof behuizing gemonteerd, zoals onder andere voor Accu Boormachines.
  • A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. They may be configured in a series, parallel or a mixture of both to deliver the desired voltage, capacity, or power density. The term battery pack is often used in reference to RC hobby toys and battery electric vehicles.Components of battery packs include the individual batteries or cells, and the interconnects which provide electrical conductivity between them. Rechargeable battery packs often contain a temperature sensor, which the battery charger uses to detect the end of charging. Interconnects are also found in batteries as they are the part which connects each cell, though batteries are most often only arranged in series strings. When wiring a pack in parallel there are various methods and one should take into consideration the balance of the electrical circuit. Battery regulators are sometimes used to keep the peak voltage of each individual battery or cell below its maximum value so to allow weaker batteries to be fully charged, bringing the whole pack back into balance. Active balancing can also be performed by battery balancer devices which can shuttle energy from strong batteries to weaker ones in real time for even better balance. A well-balanced pack lasts longer and delivers better performance so it is a rather beneficial component of high capacity or expensive packs.For an inline package, cells are selected and stacked with solder in between them. The cells are pressed together and a current pulse generates heat to solder them together and to weld all connections internal to the cell.
