摘要: An electrical energy store for a motor vehicle includes storage cells, a retaining element which is supported on the storage cells and by way of which the storage cells are fixed relative to one another, and a current collecting element common to the storage cells and held on the retaining element, to which current collecting element a terminal of each storage cell is electrically connected. The terminal of each storage cell is electrically connected to the current collecting element via a connection element, which is pre-mounted on the retaining element at a mounting point independently of the current collecting element and independently of the storage cells.

摘要: Methods and systems for welding contacts of a plurality of battery cells are provided. A method includes using a detector to perform a scan of the cell electrode contact area for each of the plurality of battery cells. Based upon the scan of each cell electrode contact area, a determination is made of whether one or more possible weld sites for each electrode contact area are viable for welding. In response to determining that one or more weld sites are viable, one or more of the viable weld sites are selected and a welder is used to weld at least one of the selected weld sites.

摘要: Provided is a method for manufacturing an electrode terminal formed of different kinds of metals excellent injunction strength. The manufacturing method of a terminal herein disclosed includes the following steps of: preparing a first member and a second member each made of a metal and forming the terminal, with the first member being formed in a sheet shape and having at one surface thereof a concave part for allowing a part of the second member to be fitted therein, and with the second member having a flange part to be accommodated in the concave part; and fixing the first member and the second member to each other by ultrasonic pressure contact, with the ultrasonic pressure contact being performed by applying an ultrasonic wave vibration while applying a pressure in a direction of stacking of the first member and the second member in a state where the flange part of the second member is arranged in the concave part of the first member, thereby extending the flange part, and bringing a part of the extended flange part into pressure contact with an inner wall surface of the concave part.

摘要: A terminal including two members excellent in junction strength and conduction is provided. The terminal herein disclosed is a terminal forming any of a positive electrode and a negative electrode of a secondary battery, and has a first member and a second member each made of a metal. The first member is formed in a sheet shape, and the second member has a crimped part opposed to the first member. Herein, at one surface of the first member, the crimped part of the second member is crimped with the first member not via a through hole, and the opposing surfaces of the first member and the second member have the metal junction surfaces metal-joined to each other.
