Lead plate, battery pack having the same, and method of manufacturing the battery pack

摘要

A lead plate that electrically connects a plurality of battery cells. The lead plate includes a first welding unit; a second welding unit separately disposed from the first welding unit by a slit between the first and second welding units; and a by-pass unit, an end of which is connected to the first welding unit and the other end of which is connected to the second welding unit, wherein the end of the by-pass unit is disposed on an opposite side of the slit based on the first welding unit, and the other end of the by-pass unit is disposed on an opposite side of the slit based on the second welding unit.

1. A lead plate for electrically connecting a plurality of battery cells, the lead plate comprising:
a first welding unit that has a width extending in a first direction and a length extending in a second direction; a second welding unit separately disposed from the first welding unit by a slit between the first and second welding units wherein the second welding unit has a width extending in the first direction and a length extending in the second direction and wherein the length of the second welding unit is aligned with the length of the first welding unit; and a by-pass unit, first end of which is connected to the first welding unit and a second end of which is connected to the second welding unit, wherein the first end of the by-pass unit is disposed on an opposite side of the slit based on the first welding unit, and the second end of the by-pass unit is disposed on an opposite side of the slit based on the second welding unit and wherein the by-pass unit has a length portion that extends in the first direction that is offset from the aligned lengths of the first and second welding units such that a gap is formed between the length portion of the by-pass unit and the first and second welding units and wherein the gap is extends in the first direction a greater distance than the slit.
