SEALED ARRAY-TO-ARRAY BUSBAR ASSEMBLIES

Sealed busbar assemblies are provided for use within traction battery packs. An exemplary sealed busbar assembly may be configured to electrically connect a first battery array and a second battery array of the traction battery pack. Primary seals and secondary seals of the sealed busbar assembly may cooperate to seal high voltage connections relative to both the first battery array and the second battery array. The high voltage connections may be established by the busbar, a pair of fasteners, and high voltage array busbars of both the first battery array and the second battery array.
