Abstract:
The present disclosure relates to a battery module that includes a housing having a first protruding shelf along a first perimeter of the housing, a second protruding shelf along a second perimeter of the housing, where the first and second protruding shelves each include an absorptive material configured to absorb a first laser emission. The battery module also includes an electronics compartment cover configured to be coupled to the housing via a first laser weld, and a cell receptacle region cover configured to be coupled to the housing via a second laser weld. The electronics compartment cover has a first transparent material configured to transmit the first laser emission toward the first protruding shelf and the cell receptacle region cover has a second transparent material configured to transmit the first laser emission or a second laser emission toward the second protruding shelf.
