Problems solved by technology

[0011] The above-mentioned patent documents have an advantage in that, in the case where an overcurrent flows in the secondary battery, components mounted on the current flow path in the secondary battery break quickly to interrupt the overcurrent, thus ensuring safety when using the secondary battery property, but it has a problem in that since the metal plate and the metal bridge are dissimilar metals, it is not easy to bond the metal plate and the metal bridge to each other, so the metal bridge must be bonded to the metal plate to wrap in the upper and lower surfaces of the metal plate The area adjacent to the slit, so that the part becomes structurally unstable, has low external impact resistance and is not easy to manufacture

Embodiment Construction

[0044] In this application, it should be understood that the terms "comprising", "having", "comprising" and the like designate the presence of the stated features, numbers, steps, operations, elements, components or combinations thereof, but do not preclude the presence or addition of one or and more other features, numbers, steps, operations, elements, components or combinations thereof.

[0045] Furthermore, throughout the drawings, the same reference numerals will be used to refer to components that perform similar functions or operations. Where a component is referred to as being connected to another component in this application, not only can the one component be directly connected to the other component, but the one component can also be indirectly connected to the other component via the other component. Furthermore, the inclusion of an element does not mean the exclusion of other elements, but rather means that other elements may be further included unless otherwise st...

Abstract

The present invention relates to an HV bus bar made of dissimilar metal and a method for manufacturing the same, and more particularly, to an HV bus bar configured to connect a plurality of battery modules to each other, the HV bus bar (100) comprising: a conductor including a first metal plate (110) and a second metal plate (120); and an insulating resin coating layer on the outer peripheral surface of the conductor, in which a first metal (111) constituting the first metal plate (110) and a second metal (121) having a lower melting temperature than the first metal (111) are mixed in the second metal plate (120) in a state in which the second metal is dispersed.

Description

technical field [0001] This application claims the benefit of priority from Korean Patent Application No. 2020-0039086 filed on March 31, 2020, the entire disclosure of which is incorporated herein by reference. [0002] The present invention relates to an HV bus bar made of dissimilar metals and a method of manufacturing the same, and more particularly, to an HV bus bar and a method of manufacturing the same, which can be highly resistant to external impact while being able to The current flow is safely interrupted and the current cutoff temperature in the battery pack can be easily adjusted. Background technique [0003] With the technological development of mobile devices such as mobile phones, laptop computers, camcorders, and digital cameras, and an increase in demand for them, research into secondary batteries capable of charging and discharging has been actively conducted. In addition, secondary batteries, which are energy sources to replace fossil fuels that cause a...
