20120208065 | Single Cell For a Battery - A single cell for a battery that includes a first housing part and a second housing part, which are electrically isolated from one another by an insulating housing frame. An electrochemically-active material is located in housing frame between housing parts. The first housing part and second housing part are in the form of plates. At least one of the housing parts exhibits a first edge area bent over towards the inside, and first housing part and second housing part are fixed by a form fit to one-piece housing frame. | 08-16-2012 |
20130045409 | Battery Having a Plurality of Single Cells - A battery is provided with a plurality of individual cells connected in series and/or in parallel to one another, and at least one cooling plate arranged on the pole side on the individual cells, with current drain tabs of electric poles of the individual cells being thermally coupled with the cooling plate and being angled such that they extend parallel to the cooling plate. Current drain tabs of adjacent individual cells are electrically interconnected in non-positive and/or in positive manner and pressed with the cooling plate in non-positive and/or in positive manner by clamping elements. | 02-21-2013 |
20140220409 | Individual Cell for a Battery, and a Battery - A single cell for a battery includes an electrode foil stack situated in a housing formed from two enveloping metal sheets and a frame that electrically insulates the two enveloping metal sheets from one another. Current discharge tabs of electrode foils of one polarity are connected to one another to form a pole contact, and the respective pole contact is connected to an enveloping metal sheet, and an enveloping metal sheet in each case forms an electrical pole of the single cell. The current discharge tabs of the same polarity are led out in each case at a pole side of the electrode foil stack and connected to one another in a middle area of the pole side. The pole contacts are angled parallel to the pole side, in particular with respect to one-half of the particular pole side, and are connected to an enveloping metal sheet. | 08-07-2014 |
20140242446 | Single Cell for a Battery, and a Battery - A single cell for a battery includes two housing parts, a cell frame, an electrode foil stack situated between the housing parts, and an insulating element situated between the housing parts. The insulating element electrically separates the two housing parts from one another. The insulating element has dimensions such that in the assembled state of the single cell the insulating element projects, at least in part, beyond a first housing part at the edge, forming a projection. The first housing part is enclosed, at least in part, by the insulating element at an edge. | 08-28-2014 |
20140363704 | Battery Comprising a Number of Individual Cells Connected Electrically to One Another and Method for Maintaining, Repairing and/or Optimizing such a Battery - A battery includes a number of single cells interconnected in series and/or in parallel, the electrical poles of which for the electrical interconnection are connected to one another in a positive-fit and/or integrally bonded manner, directly or by means of cell connectors. The battery also includes a battery monitoring unit connected to the electrical poles and/or to the cell connectors in a positive-fit and/or integrally bonded manner. The electrical poles of the single cells, the cell connectors, and/or the battery monitoring unit have redundant contact areas for the positive-fit and/or integrally bonded connection. In each case only one of the contact areas which are redundant with one another is connected in a positive-fit and/or integrally bonded manner, and the further contact area(s) is/are not connected. | 12-11-2014 |
20150104686 | Battery and Cell Block for a Battery - A cell block for a battery includes a number of electrochemical single cells electrically connected to one another in series and/or in parallel. The single cells are flat cells oriented essentially in parallel and situated one behind the other in the cell block, and are tensioned with respect to one another by a tensioning element. The tensioning element is a temperature control plate for controlling the temperature of the single cells. The temperature control plate is situated on a longitudinal side of the cell block and thermally coupled to the single cells. | 04-16-2015 |
