Abstract
Official abstract text for this publication.
A bus bar includes terminal portions disposed at both ends, respectively; a plurality of bridges disposed between the terminal portions to electrically connect the terminal portions, and to be sequentially fused when an overcurrent flows. The plurality of bridges may be configured to have different resistance values, respectively.
First claim
Opening claim text (preview).
What is claimed is: 1. A bus bar, comprising: terminal portions disposed at both ends thereof, respectively; and a plurality of bridges disposed between the terminal portions to electrically connect the terminal portions, and to be sequentially fused when an overcurrent flows, wherein the plurality of bridges are formed to have different cross-sectional areas, and different resistance values, respectively, and wherein the plurality of bridges are connected to each other in parallel. 2. The bus bar of claim 1 , wherein the plurality of bridges are formed such that any one of a width, a length, and a thickness thereof is different. 3. The bus bar of claim 1 , wherein the plurality of bridges are formed of different materials from each other. 4. The bus bar of claim 1 , wherein a penetrating portion having a through-hole shape is disposed between the bridges. 5. The bus bar of claim 1 , wherein at least one of the bridges comprises a narrow section having a narrower width. 6. The bus bar of claim 1 , wherein at least one of the bridges is configured such that at least a portion thereof are disposed to be protruded to one side. 7. The bus bar of claim 1 , wherein the plurality of bridges are sequentially fused from the bridge having the lowest resistance value when an overcurrent flows in the bus bar. 8. The bus bar of claim 1 , wherein the bridges are composed of four bridges, wherein when a resistance value of the first bridge is 1, it is configured such that a resistance value of the second bridge is 2, a resistance value of the third bridge is 3, a resistance value of the fourth bridge is 3.5. 9. The bus bar of claim 1 , wherein the resistance value of the first bridge, among the plurality of bridges, is lower than the resistance values of the remaining bridges, wherein the resistance values of the remaining bridges are set to be gradually higher than the resistance value of the first bridge. 10. A battery pack, comprising: at least one bus bar as described in claim 1 ; and a plurality of battery modules electrically connected through the bus bar.
