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.
