Patent ID: 8206846

Claim:
A battery module including a plurality of battery cells or unit modules, the 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, wherein the downwardly bent portion is surrounded by an insulative band for preventing the downwardly bent portion from being restored to an original state thereof, in which the insulative band is configured in a shape of a hollow pipe for surrounding a wire corresponding to the downwardly bent portion, the hollow pipe being filled with a moisture absorbing material.
