MEDIUM OR LARGE SIZED BATTERY MODULE HAVING IMPROVED SAFETY

摘要

The present invention provides a medium or large sized battery module among battery modules consisting of multiple battery cells or unit modules, wherein the medium or large sized battery module has a connection structure for transmitting and receiving a measured voltage and/or a temperature signal through a wire-typed connection member. The medium or large sized battery module includes at least one end portion of the connection member which is mechanically coupled to a connection correspondence unit through a male-female coupling method. A wire of the connection member includes a part (downward-bent part) which is bent downward at a lower height than the connection coupling unit at the region adjacent to the connection coupling unit in case the moisture condensed on the connection member should flow into the connection coupling unit due to gravity.
