UV COATING FOR DIELECTRIC INSULATION
20230002636 · 2023-01-05 ·

A UV curable dielectric coating is described. The curable coating can include one of more acrylate monomers, a urethane prepolymer, a crosslinker, at least one adhesion promoter, a photoinitiator, and optionally one or more fillers and/or additives. The coating can be used to insulate battery cells and battery packs, such as those used in electric vehicles. The coatings can be easily applied and quickly cured. The cured coatings can have high adhesion strength, even after exposure to wet conditions.

BATTERY ENCLOSURE

A battery enclosure and method for manufacturing the same from organosheet materials. The battery enclosure includes a top cover with crossbeams integrated therein by overmolding that secures to a bottom panel to enclose a space for containing components of a battery. The bottom panel includes overmolded structural ribs to provide strength and rigidity to the bottom panel. An outer cover removably secure the top cover to the bottom panel and includes a honeycomb structure to crush upon impact and protect the battery components. The method comprises forming each of the components of the battery enclosure from a mixture of organosheets, reinforcing members, and overmolded elements to reduce the weight and complexity of manufacturing for the battery enclosure.
