Abstract:
The present disclosure includes a battery module having a first electrochemical cell and a second electrochemical cell positioned adjacent to the first electrochemical cell. The battery module also includes a separator plate disposed between the first electrochemical cell and the second electrochemical cell. The separator plate includes a body comprising a first side and a second side opposite the first side. The first side is disposed adjacent a first face of the first electrochemical cell and includes a first indention. The first indention defines a first space between the first face of the first electrochemical cell and the first side of the separator plate. The first space is configured to enable swelling of the first electrochemical cell into the first space.
Abstract:
The present disclosure relates to a battery module having a housing and a stack of battery cells disposed in a receptacle area of the housing, where each battery cell has a top having a battery cell terminal and a bottom, where the top of the battery cells face outwardly away from the receptacle area. The battery module includes an integrated sensing and bus bar subassembly positioned against the stack of battery cells and has a carrier, a bus bar integrated onto the carrier, and a biasing member integrated onto the carrier. The bus bar electrically couples battery cells in an electrical arrangement, and the biasing member is between the top of each battery cell and the carrier, where the biasing member has a first material, more compliant than a second material of the carrier, and the biasing member biases the stack of battery cells inwardly toward the housing.

Abstract:
The present disclosure provides a battery pack including a housing, wherein the housing has a bottom portion and side walls extending upward around a periphery of the bottom portion; an upper portion opening is formed at top ends of the side walls extending upward; an upper cover is mounted on the upper portion opening of the housing; and the battery pack comprises: multiple flat battery cells; and a first end plate and a second end plate, wherein when the multiple battery cells are sequentially arranged and mounted into the housing from the upper portion opening, the first end plate and the second end plate are located at two end sides of the sequentially arranged multiple battery cells to laterally fix the sequentially arranged multiple battery cells. The two end plates may absorb deformation of the battery cell while expanding.
Abstract:
The present disclosure relates to a stacked cell manufacturing scheme for battery modules. A disclosed method of manufacturing a battery module includes assembling a plurality of prismatic battery cells of the battery module into a cell stack. The method includes compressing the cell stack using an actuating clamping mechanism, inserting the cell stack into a housing of the battery module with the actuating clamping mechanism engaged with and compressing the cell stack, and removing the actuating clamping mechanism from the cell stack. The housing of battery module maintains a compression of the cell stack above a predetermined threshold in the battery module after removing the actuating clamping mechanism.
