The invention discloses a
busbar of a high-rate discharging module. The
busbar comprise a
busbar body, the busbar body is composed of two
layers of base materials, battery-
cell-polarity observing holes are formed in the two
layers of base materials of the busbar body through penetrating, and positions of the battery-
cell-polarity observing holes correspond to pole-column identification positions of battery cells;
welding area holes are formed in the first layer of base material of the busbar body, positions of the battery-
cell-polarity observing holes correspond to pole-column positions of thebattery cells, and
welding observing holes are formed in the portions, located in the
welding area holes, of the second layer of base material of the busbar body. The busbar has the advantages that the structure is ingenious, the busbar completely fits pole columns of the battery cells,
laser welding welding is achieved, and the performance is safe and stable; the busbar is formed through
stamping and bending of the single layer of base material, the cost is low, the requirement of the high-rate discharging module can be met, the
processing labor hour is short, manpower and material resourcesare saved, dissipation is reduced, and batch and automatic production can be achieved.
