Elektrische Verbindungsanordnung und elektrisches Verbindungsverfahren für Batterien

摘要

A connection structure of battery is presented for composing a storage battery module of specified output voltage by connecting plural cells having small electric power loss between connected cells and excellent mechanical strength. This is a connection structure of battery connecting a first cell (100A) and a second cell (100B) in series by using a connection member (1). Each one of the first cell and second cell has (a) a metal outer member in a container shape (11) as the negative electrode installing plural function element members inside, and (b) a metal electrode member (10) installed at one end, being electrically insulated from the outer member, including a first flat portion as the positive electrode. The connection member (1) has a side wall (4) capable of fitting the outer member inside, and a second flat portion (5) orthogonal to the side wall. A first projection (2) for welding to the electrode member is installed on the second flat portion. A second projection (3) for welding to the outer member is installed on an inside surface of the wall. The first projection of the electrode member abuts against the first surface of the first cell and is welded and joined. The side wall of the connection member is fitted to the outside of the outer member of the first cell, and the second projection of the connection member abuts against the surface of the outer member of the second cell, and is welded and joined.
