Patent

CA 2402455

A valve-regulated lead acid (VRLA) battery cell (2, 40) has positive and negative plates (10, 11, 41, 42) separated by separator media (12, 43) and held together under pressure. The separator is adapted to support therein an electrolyte. Each plate has a first single or plurality of tabs (12, 13, 46) on a first side and a second single or plurality of tabs (15, 16, 47) on a second side of the plate, each tab being connected to a busbar (17, 18, 49, 50) to form positive and negative busbars on each of the first and second sides of the plate. The cell may be alternatively configured in a spirally- wound arrangement or in a prismatic arrangement of flat plates. The cell may be constructed of a plurality of such positive and negative plates. A VLRA battery (1, 40) may be constructed of one or a plurality of such VLRA cells, in which case the busbars of neighboring cells are connected by welded joints. The busbars are serviced by at least plural pairs of positive and negative terminals (24, 25, 33, 34, 52, 53, 54, 55).

L'invention concerne un élément d'accumulateur au plomb à soupape de régulation (VRLA) (2, 40) comprenant des plaques positives et négatives (10, 11, 41, 42) séparées par des unités de séparateur (12, 43) et retenues ensemble sous pression. Le séparateur est conçu pour y supporter un électrolyte. Chaque plaque comporte une ou plusieurs premières languettes (12, 13, 46) sur un premier côté, et une ou plusieurs secondes languettes (15, 16, 47) sur un second côté, chaque languette étant reliée à une barre omnibus (17, 18, 49, 50) de manière à former des barres omnibus positives et négatives sur chacun desdits premier et second côtés de la plaque. Dans un autre mode de réalisation, chaque élément peut être disposé selon un agencement spiralé ou prismatique de plaques planes. Ledit élément peut être constitué par une pluralité de plaques positives et négatives. Un accumulateur VRLA (1, 40) peut être constitué par un ou plusieurs de ces éléments VRLA, les barres omnibus des éléments voisins étant alors connectées par des joints soudés. Ces barres omnibus sont desservies par plusieurs paires au moins de bornes positives et négatives (24, 25, 33, 34, 52, 53, 54, 55).
