Abstract
Le bloc-batterie (1) comprend une pluralité de cellules d’accumulation électrique (2) ayant chacune des première et deuxième surfaces de contact (2A, 2B) avec des polarités électriques distinctes, des premier et deuxième bus-barres électriques (4A, 4B) reliés par soudure (6A, 7A) respectivement aux première et deuxième surfaces de contact, et des premier et deuxième dissipateurs thermiques (3A, 3B) plaqués respectivement contre lesdits premier et deuxième bus-barres électriques. Conformément à l’invention, les premier et deuxième dissipateurs thermiques (3A, 3B) comprennent respectivement des première et deuxième pluralité d’orifices (30A, 30B) situés en correspondance avec les première et deuxième surfaces de contact et autorisant un accès pour ladite soudure.
