Embodiment Construction

[0033] see Figure 1-5 , the battery module 10 according to the exemplary embodiment is provided. The battery module 10 includes frame members 20, 22, 24, 26, 28, 30, battery cells 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, an interconnect assembly 90, Detachable wire harness assembly 92 , interconnect assembly 94 , detachable wire harness assembly 96 and end plates 100 , 102 . An advantage of the battery module 10 is that the module 10 utilizes interconnect assemblies 90, 94 each having voltage sensing members that can be easily laser welded to the electrical terminals of the battery cells.

[0034] In addition, the battery module 10 utilizes frame extensions on the frame members and blade portions on the interconnect assembly to electrically isolate each pair of electrical terminals that are disposed in close proximity to each other, each pair of electrical terminals being separated by an air gap to prevent passage of air. Gap discharge. In particular, when the frame...

Abstract

A battery module and a method are provided. The battery module includes a first battery cell having a first electrical terminal, a second battery cell having a second electrical terminal, and an interconnect assembly having a plate portion, first and second finger portions, a blade portion, and first and second voltage sense members. The first and second voltage sense members are coupled to the first and second finger portions, respectively. The blade portion is disposed between the first and second finger portions such that a first gap is defined between the first finger portion and the blade portion, and a second gap is defined between the second finger portion and the blade portion. The first and second electrical terminals extend through the first and second gaps, respectively, and are coupled to the first and second voltage sense members, respectively.

Description

technical field [0001] This application claims the benefit of US Patent Application No. 14 / 617,344, filed February 9, 2015 in the US Patent and Trademark Office, the disclosure of which is incorporated herein by reference in its entirety. [0002] The present invention relates to battery modules and methods of coupling first and second terminals of first and second battery cells to first and second voltage sensing members of an interconnect assembly. Background technique [0003] The conventional battery module has a problem of a long and complicated assembly process because it is difficult to connect a member for measuring the voltage of the battery cell to the terminal of the battery cell, thereby increasing the manufacturing cost. [0004] The inventors herein have recognized a need for improved battery modules and methods of coupling first and second terminals of first and second battery cells to first and second voltage sensing members, respectively, of an interconnect ...
