摘要： A structural assembly for a battery structure includes a lower wall and a pair of cross members. The lower wall is configured to support a cell stack. The cross members are spaced apart from each other in a longitudinal direction of a vehicle. Each cross member supports a respective side of the cell stack and is configured to extend substantially an entire width of the battery structure. Each cross member includes an outer wall, an inner wall, and connecting members that connect the outer wall to the inner wall. The outer wall, the inner wall, and the connecting members cooperate to define an internal cavity. The inner walls of the cross members are secured to the lower wall to form a unitized structure that houses the cell stack.

摘要： A structural assembly for a battery structure of a vehicle includes a lower wall and a pair of cross members. The lower wall is configured to support a cell stack. The pair of cross members are spaced apart from each other in a longitudinal direction of the vehicle. Each cross member provides lateral support for a respective side of the cell stack and is configured to extend substantially an entire width of a battery enclosure. Each cross member of the pair of cross members includes an outer wall, an inner wall spaced apart from the outer wall, and connecting members. The outer wall, the inner wall, and connecting members cooperate with each other to define an internal cavity. The inner walls of the pair of cross members are secured to the lower wall and slidable relative to the outer walls of the pair of cross members.

摘要： A battery, such as a traction battery for an electrified vehicle (EV), includes a battery sensor, such as a battery pack sensing module (BPSM), arranged internally within a housing of the battery. The battery further includes one or more battery cell arrays arranged within the housing. Each battery cell array including battery cells and a printed circuit board (PCB) electrically connected with voltage sense leads associated with the battery cells. The battery further includes a primary PCB arranged within the housing and electrically connected to the battery cell array PCBs. The battery sensor is electrically connected to the primary PCB to establish an electrical connection with the battery cell array PCBs whereby the battery sensor can sense the voltages of the battery cells.
