Abstract: Devices, methods, and systems for interconnecting all of the battery cells in a battery module from a single side of the battery cell and module are provided. The cell busbar system comprises a number of thin formed strips arranged to interconnect individual battery cells in a row together in series and each row in parallel along a length of the battery module. In particular, the cell busbar system may include two high voltage, or edge, strips and a number of cell-to-cell, or internal, strips electrically interconnected to the edge strips. All of the battery cells in the battery module may be oriented such that all of the positive terminals are facing the same direction. The interconnections between series-connected rows of cells, and parallel rows of series-connected rows, may all be made in substantially the same plane on a single side of the battery module.

Abstract: Embodiments are directed to contact plates configured to establish electrical bonds between battery cells in a battery module. In a first embodiment, the contact plate includes at least one primary conductive layer including a hole that is aligned with two or more terminals of two or more battery cells in a group of battery cells that are configured to be connected in parallel with each other, and a bonding connector configured to provide direct electrical bonds between the contact plate and the two or more terminals of the two or more battery cells. In a second embodiment, a contact plate includes at least one primary conductive layer and a set of bonding connectors made from at least one material that is selected to match at least one material used for the terminals of the at least one group of battery cells.

Abstract: The invention relates to a battery cell connector 1 comprising a first terminal part 2 formed for connection to a battery terminal of a first battery, a second terminal part 4, and a connecting part 6 which is arranged between the terminal parts 2, 4 and electrically connects the terminal parts 2, 4 to one another. Uniform connection of battery terminals 22, 24 is ensured in that the first terminal part 2 is formed at least on the side A facing towards a battery terminal 22, 24 from a first electrically conductive material, and in that a flat piece 8, which is formed for connection to a second battery terminal 22, 24 and is formed at least on the side A facing the second battery terminal from a second electrically conductive material different from the first electrically conductive material, is arranged with a material fit on the second terminal part 4.

Abstract: A battery terminal in which opening of the inserting member of the electrode can be controlled so that the battery electrode is connected promptly and firmly, transformation of the electrode can be avoided by preventing excessively tight connection of the electrode, electric resistance is reduced by maximizing contacting surface of the electrode thereby enhancing electric conductivity, and connecting process is conveniently carried out by fastening the bolt which controls the opening of the inserting member at upper portion of the device.

Abstract: The invention proposes a terminal contact for electric conductors in an insulating housing (1) with electric contacts that are arranged in separate chambers (11), wherein a clamping sleeve (3) is in axial alignment with and connected to a slide element (2) that is also arranged in the chambers (11). A single-wire or multi-wire electric conductor that is inserted into a through-bore of the slide element and the clamping sleeve connected thereto is pushed over a stationary, rigid and barb-shaped terminal region of the conductor rail while the slide element is axially moved along the chamber, wherein the strands are clamped between the terminal region and the clamping sleeve.

Abstract: A battery terminal connector for connecting a battery cable to a battery terminal post includes a clamp body, a compression ring and a compression plate. The clamp body has a tapered hole for loosely receiving the battery terminal post. The conductive compression ring has a tapered inner peripheral wall and a tapered outer peripheral wall and is sized to fit into the tapered hole of the clamp body and over the battery terminal post. The taper of the inner and outer peripheral walls of the ring are opposed to each other. A compression plate is mounted to the clamp body and includes a flange for pressing the compression ring into the tapered hole to compress the ring and achieve tight electrical contact among the terminal post, the compression ring and the clamp body. The clamp body, the compression ring and the compression plate are made of a material having a hardness of at least about 60 on the Rockwell B scale.

Abstract: A connector requiring minimal insertion force and forming a reliable connection has a female terminal and a male terminal. A shaft portion of the male terminal is insertable into a closed end insertion tubular portion of the female terminal. The shaft portion has an expanding slot extending along a length thereof. A projection is provided within the insertion tubular portion near the closed end. A bore diameter of the insertion tubular portion is larger than a diameter of a portion of the shaft portion that is to be first inserted. At a final stage of an insertion operation, the projection fits in the expanding slot. Accordingly, at the final stage of the insertion operation, the shaft portion is forcibly expanded radially outward and brought into contact with the bore wall of the insertion tubular portion at a predetermined contact pressure.

Abstract: An electrical coupling for a power supply busbar has a U-shape metal body that embraces the busbar and is locked in place by a pin that extends through apertures in opposite limbs of the body. The pin has a shoulder that urges the bar against a flexible metal strip retained in a groove in the body. A plastics sleeve embraces the body and retains the pin in place, the sleeve being retained by a cable stud screwed into the body.
