Embodiment Construction

[0066] Now, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted, however, that the scope of the present invention is not limited to the illustrated embodiments.

[0067] figure 1 is a typical view showing a medium-to-large battery module using a conventional wire-type connection member.

[0068] exist figure 1 In the medium and large battery module 10, the wire-type connection member 20 may be a wire harness, and a connection part 22 is provided at one end of the wire-type connection member 20, and the connection part 22 is connected to the corresponding connection part 32 in a convex-convex connection. The corresponding part 32 is provided at the top of the battery management system (BMS) 30 .

[0069] However, in this structure, the moisture condensed on the surface of the wire type connection member 20 flows from the uppermost end 24 of the wire type connection member 20 to the connect...

Abstract

Disclosed herein is a middle- or large-sized battery module including a plurality of battery cells or unit modules, the middle- or large-sized battery module being configured to have a connection structure in which measured voltage and / or temperature signals of the battery cells or the unit modules are transmitted and received by a wire type connection member, wherein at least one end of the connection member is connected to a connection counterpart in a male and female engagement type mechanical coupling manner, the connection member has a downwardly bent region (a downwardly bent portion) formed at a region adjacent to a connection part such that the downwardly bent portion is bent downward to a height lower than the connection part for preventing moisture condensed on the connection member from being introduced to the connection part due to gravity.

Description

technical field [0001] The present invention relates to a medium-to-large battery module with improved safety, and more particularly, to a medium-to-large battery module including a plurality of battery cells or unit modules, the medium-to-large battery module is configured to have the following connection structure: In this connection structure, the measured voltage and / or temperature signal of the battery cell or unit module is transmitted and received through a wire-type connection member; wherein, at least one end of the connection member is connected to the connection counterpart (connection counterpart), the connection member has a downwardly bent region (downwardly bent portion) formed at a region adjacent to the connection portion so that the downwardly bent portion The bow is lowered to a lower height than the connecting part to prevent moisture condensed on the connecting member from being introduced into the connecting part due to gravity.
