SYSTEM AND METHOD FOR ESTABLISHING CONNECTIONS OF A BATTERY MODULE

摘要

A battery module includes a housing and battery cells disposed in the housing, each of the battery cells including two terminals. The battery module also includes bus bar cell interconnects including a first material, where each bus bar cell interconnect is configured to electrically couple two adjacent battery cells via an electrical coupling with a first terminal of one of the adjacent battery cells and a second terminal of the other adjacent battery cell, where at least one of the first and second terminals includes the first material. The battery module includes welds, each weld being disposed at a corresponding welding point to directly couple one of the bus bar cell interconnects with the corresponding at least one terminal including the first material. Each welding point is accessible for welding from a position above the battery cells when the interconnects are disposed over the battery cells.

主权项

1. A battery module, comprising:
a first battery cell comprising a first terminal; a second battery cell adjacent to the first battery cell, the second battery cell comprising a second terminal; a bus bar cell interconnect coupled to the first terminal of the first battery and the second terminal of the second battery; a printed circuit board comprising a voltage sense terminal; and a wire bonded connection comprising a wire welded to the bus bar cell interconnect and electrically coupled to the voltage sense terminal of the printed circuit board.
