  • the above-mentioned conventional battery pack has the advantage of being easy to arrange and configure battery cells, and is widely used because it can be manufactured at low production costs by using basic parts.
  • Conventional battery packs are made by arranging multiple battery cells in parallel and then fixing them together using nickel plates. If one of the battery cells constituting the battery pack is defective, problems may occur with the overall performance (output) of the battery pack. In addition, not only may the set voltage value not be obtained due to the defective battery cell, but other connected battery cells may be overcharged during the charging process, and when discharging, multiple connected battery cells may discharge rapidly, making it difficult to maintain the set characteristics of the battery pack.

Abstract

La présente invention concerne un bloc-batterie qui est doté d'une configuration simplifiée, et qui peut être facilement entretenu/réparé. La présente invention est configurée par agencement d'au moins deux supports de batterie (10) en parallèle à des intervalles égaux sur une carte de circuit imprimé (P) et par combinaison d'un élément de batterie (C) avec chacun des supports de batterie (10). La présente invention est avantageuse en ce que le remplacement d'un élément de batterie défectueux peut être réalisé de manière pratique en permettant un détachement facile de la batterie, et en utilisant un port de connexion installé sur une carte de circuit imprimé, le fonctionnement du bloc-batterie peut être étendu ou l'équilibrage du bloc-batterie peut être surveillé à l'aide d'une borne externe, ce qui permet d'améliorer l'efficacité opérationnelle du bloc-batterie.
