The invention relates to a fireproof plate integrated with a
busbar and a
battery pack, the fireproof plate integrated with the
busbar comprises a fireproof plate body and the
busbar, the busbar is integrally assembled on the fireproof plate body, and at least one part of the surface of the busbar is exposed from the fireproof plate body and is used for connecting a
battery cell tab. According to the fireproof plate disclosed by the invention, the busbars are integrated on the fireproof plate, and when the fireproof plate is used, the
battery cell tabs on which the battery cells are laid can be directly welded on the busbars of the fireproof plate body, so that the electric connection between the battery cells is realized. According to the module-free
battery pack, the busbars are integrated on the fireproof plates, so that parts are reduced, the
assembly process is simplified, the structure is simple, the assembled module-free
battery pack is compact in internal structure and good in stability, the internal space of the battery pack is saved, and the battery pack is high in
energy density and good in safety performance; the light weight of the battery pack is realized, and the
automation degree is high.
