Battery cover assembly

摘要

An end-to-end cell connection system for a battery assembly uses a conductive interconnector with an inner portion welded to an end of one cell, a standoff portion contiguous with the ring portion, tabs extending from the standoff portion, with the tabs welded to an end of another cell. By placing an insulator between the interconnector and the one cell, an electrical short is prevented in the event that a longitudinally coupled cell group is jostled. At the cell connections, there is a recess. To hold the cell group in place, the housing has a tab extending into the recess. The tab is at the center so that any dimensional variations are accommodated on each side of the tab. The interconnector also may include a receptacle for a thermistor to obtain a measure of battery assembly temperature. Diverter ribs may be provided in the housing to distribute flow to all cells.

主权项

1. A battery, comprising:
a plurality of cell groups, each group comprising a plurality of cells coupled longitudinally; a plurality of cell housings each having at least one cell group within, the cell housings arranged in an array; indexing tabs extending from an outside surface of each cell housing forming a channel along the array; and a cover having a groove formed therein for mating with the channel when the cover is placed over the array.
