1. A busbar assembly, comprising: a first busbar, wherein the first busbar is configured to connect two adjacent battery units; and the first busbar includes:
a first connection part, wherein the first connection part is configured to connect a first electrode terminal of one of the two adjacent battery units; and
a second connection part, wherein the second connection part is configured to connect a second electrode terminal of the other one of the two adjacent battery units, and the second connection part and the first connection part are in staggered arrangement, to be configured to match a vertical distance between a lead surface of the second electrode terminal and a lead surface of the first electrode terminal located on a same side of the battery units,
wherein the first busbar further comprises a bent part, and the bent part is configured to form a distance difference between the first connection part and the second connection part in staggered arrangement,
the bent part is provided with a buffer structure for enhancing a structural strength of the bent part, and an extending direction of the bent part is changed to form the buffer structure,
one side of the first connection part facing away from the buffer structure is provided with a notch structure, and a shape of the notch structure is adapted to a shape of the buffer structure,
the first busbar is multiple in number, the plurality of first busbars are arranged in sequence, in two adjacent first busbars: the notch structure of the first connection part of the latter one of the plurality of first busbars matches the buffer structure of the former one of the plurality of first busbars, and a gap is defined between the notch structure and the buffer structure along an arrangement direction of the two first busbars.
