Battery module printed circuit board assembly system and method

A battery module comprising:

• a lower housing;
• a plurality of battery cells, wherein the plurality of battery cells are electrically coupled together to produce a voltage;
• a first assembly disposed over the battery cells and coupled to the lower housing, wherein the first assembly comprises a lid including a plurality of asymmetrical indentations disposed therein and a plurality of asymmetrical bus bar interconnects received within the asymmetrical indentations of the lid, each bus bar interconnect of the plurality of bus bar asymmetrical interconnects being a single piece component having a first portion made of a first material and a second portion made of a second material different from the first material and having an asymmetry readily indicating orientation placement of the asymmetrical bus bar interconnects within the asymmetrical indentations of the lid, the first portion having a first peripheral shape and the second portion having a second peripheral shape, and the asymmetry provided by the second peripheral shape;
• a printed circuit board (PCB) assembly disposed on and coupled to the first assembly, wherein the PCB assembly comprises a PCB;
• and
• a cover disposed over and coupled to the lower housing to hermetically seal the battery module.
