Abstract
A cell connection strap for electrically connecting a pair of adjacent battery cells within a battery pack includes, in one example, a fusible link for preventing a thermal runaway condition from occurring in a cell connected thereto. The strap may include raised features thereon for permitting relative movement between the cells in the pack due to vibration or an impact of the pack from translating stress to welds connecting the straps to the cells. In another example, the body of the cell strap may include slits formed in sides thereof to reduce rigidity of the strap for protecting the welds between strap and cell, and also provides a fusible link capability in the strap for preventing a thermal runaway condition from occurring in a cell connected thereto.
