The present disclosure includes a battery module having a housing with a first end (having a cell receptacle region) and a second end opposite to the first end. The battery module includes a stack of electrochemical cells inserted through the cell receptacle region of the housing, disposed between the first end and the second end of the housing, and having terminal ends of all the electrochemical cells of the stack aligned in a planar area. The battery module includes a bus bar carrier disposed over the stack of electrochemical cells and within the cell receptacle region of the housing. The bus bar carrier includes bus bars disposed thereon that interface with the terminal ends. The battery module includes a layer of thermal epoxy disposed between the second end of the housing and a bottom side of the stack of electrochemical cells.

Thermal epoxy and positioning of electrochemical cells

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.
