Abstract:
A battery module (22) and a method of manufacture are provided. The battery module (22) may include a printed circuit board (PCB) assembly (58). The PCB assembly (58) may include a PCB (136) designed to be disposed in a battery module (22) for controlling operations of the battery module (22). The PCB (136) may also include voltage sensing circuitry. In addition, the PCB (136) assembly may include a bus bar cell interconnect (222). The bus bar cell interconnect (222) may electrically couple batteries (54) of the battery module (22). The PCB assembly (58) may also include a voltage sense connection tab (226). The voltage sense connection tab (226) may carry a voltage between a bus bar cell interconnect (22) of the battery module (22) and the voltage sensing circuitry on the PCB (58).
Abstract:
The present disclosure includes a battery module having a housing with a wall that includes an aperture in the wall. The battery module also includes an electrochemical cell having a terminal end and a base end opposite the terminal end. The electrochemical cell is disposed within the housing such that the base end is positioned proximate to the aperture of the wall. Further, a heat sink of the battery module is engaged with the aperture and includes cooling fins extending outwardly from the heat sink a first distance from an external surface of the wall. The battery module also includes feet of the housing extending outwardly from the wall a second distance from the external surface of the wall. The second distance is greater than the first distance.
Abstract:
A method of manufacturing a battery module 22 for use in a vehicle 10 is presented. The method may include disposing battery cells 54 into a lower housing 50 and disposing a lid assembly 56 over the battery cells 54. The lid assembly 56 may include a lid 52 and bus bar interconnects disposed on the lid 52. The method may also include disposing a printed circuit board (PCB) assembly 58 onto the lid assembly 56 and electrically coupling portions of the lid assembly 56, portions of the PCB assembly 58, and the battery cells 54 to each other. The PCB is a multi-layered PCB with internal signal, power and ground layers and external ground cage layers for shielding from electrical noise.

Abstract:
The present disclosure includes a battery module that includes an electrochemical cell having a minor terminal. The battery module also includes a major terminal electrically coupled to the electrochemical cell, wherein the major terminal includes a base and a post extending from the base. Further, the battery module includes an electrical path between the minor terminal of the electrochemical cell and the major terminal of the battery module. The electrical path includes a bus bar having an opening that receives the post of the major terminal and a pocket that retains the base of the major terminal.
