A thermal imaging system for a battery module enclosure that includes first and second battery module enclosure components between which a weld is formed includes a thermal imaging camera that focuses on the first and second battery module enclosure components within a predetermined amount of time after the weld is formed and that acquires a thermal signature. A control module includes an image processing module that receives the thermal signature and that locates a predetermined reference point in the thermal signature. An image comparison module receives the thermal signature and uses the predetermined reference point to compare the thermal signature to a template signature in order to verify structural integrity of the weld. The image comparison module computes a relative measure of deviation of the thermal signature from the template signature and identifies the weld as defective when the relative measure of deviation is greater than a predetermined value.

A through transmission laser welding system for a battery module enclosure includes a first battery module enclosure component. A second battery module enclosure component interfaces with the first battery module enclosure component. A laser source focuses a laser beam on a junction between the first and second battery module enclosure components in order to form a weld between the first and second battery module enclosure components. The first and second battery module enclosure components comprise polymeric thermoplastics. The first battery module enclosure component is transmissive to a wavelength of the laser beam and the second battery module enclosure component is opaque to a wavelength of the laser beam. Alternatively, both the first and second battery module enclosure components are transmissive to a wavelength of the laser beam, and a laser absorbing coating is applied at an interface between the first and second battery module enclosure components.

The present invention discloses is a battery case, comprising a base case and an insert as two parts of the exterior case. The base case is formed of a first polymeric material and the insert is formed of a second polymeric material, wherein the second polymeric material has a higher thermal conductivity than the first polymeric material. The second polymeric material may comprise a base polymer and at least one thermally conductive filler, such as ceramic, glass or carbon fiber. The base polymer of the second polymeric material may be selected from the group consisting of polyphenylene ether, polystyrene, polypropylene, polyphenylene sulfide and the ceramic filler may be selected from the group consisting of alumina, fused silica, a glass ceramic sold under the trademark MACOR, boron nitride, silicon nitride, boron carbide, aluminum nitride, silicon carbide, zirconia and combinations thereof. The first polymeric material may be selected from the group consisting of polyphenylene ether, polystyrene, polypropylene, polyphenylene sulfide. The base case and insert may be integrally molded by one of two-color molding and insert molding with the first polymeric material and the second polymeric material. The battery case of the present invention may comprise a monoblock alkaline storage battery case.
