BATTERY MODULE AND BATTERY PACK INCLUDING THE SAME

摘要

Disclosed is a battery module in which a novel voltage detection structure is applied to a plurality of secondary batteries formed in a cell assembly. According to the present invention, the battery module comprises: the cell assembly in which the secondary batteries having an electrode lead in a plate form are arranged in layers in upper and lower directions, and a bending part uniformly erected in upper and lower directions is formed on at least a part; a plurality of sensing plates made of an electrically conductive material, formed in a plate form to be erected in upper and lower directions, and where one end is in face-to-face contact with the bending unit of the electrode lead, and is welded; and a sensing assembly having a connector electrically connected with the other end of the sensing plate and transferring the sensed voltage, and sensing the voltage of the secondary battery.
