  • Laser welding of battery module enclosure components
    Publication number: 20060278617
    Abstract: 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.
