BATTERY PACK PREPARED USING ELECTRICAL CONNECTING MEMBER FOR BATTERY CELL WITH CONTACT BENDING PART

摘要

The present invention relates to a battery pack prepared by using a connection member for a battery cell, in which a contact bent portion is formed. More specifically, the present invention provides a battery module having a structure in which a plurality of battery cells are provided in a cell frame in a state of being electrically connected by a connection member. The battery module comprises: a connection member which is made of a metal plate and has weld portions located at both ends of a plate body and electrically connected to electrode terminals of the battery cells through welding; a cell frame which defines an opening having a shape corresponding to the connection member such that the connection member is exposed to the outside; and at least one contact bent portion which extends from the plate body or the weld portion in a bent shape on an outer circumference of at least one of the plate body or the weld portion and closely contacts an inner surface of the opening in the cell frame such that the connection member is fixed in position of the opening in the cell frame.
