  • Busbar assembly and assembling method thereof, assembly tool and battery pack
    Patent number: 12255356
    Abstract: A busbar assembly includes a first busbar configured to connect two adjacent battery units. The first busbar includes a first connection part and a second connection part. The first connection part is used to connect a first electrode terminal of one of the battery units. The second connection part is used to connect the second electrode terminal of the other one of the battery units, and the second connection part and the first connection part are in staggered arrangement. The first connection part and the second connection part of the first busbar are in staggered arrangement, to match a vertical distance between a lead surface of the second electrode terminal and a lead surface of the first electrode terminal on a same side of the battery units.

  • INSULATING FILM ASSEMBLY AND BATTERY APPARATUS
    Publication number: 20230344098
    Abstract: The insulating film assembly includes a first insulating film and a second insulating film. The first insulating film is provided with a first buffering via. The first insulating film and the second insulating film are opposite to each other. The second insulating film is provided with a second buffering via. An orthographic projection of the second buffering via on the first insulating film and the first buffering via do not have overlapping regions. The first insulating film is further provided with a first buffering groove, and the first buffering groove communicates with the first buffering via. The second insulating film is further provided with a second buffering groove, and the second buffering groove communicates with the second buffering via. An orthographic projection region of the second buffering groove on the first insulating film at least partially overlaps with the first buffering groove.
