Provided is a battery module. The battery module includes: a plurality of battery packs; a bus bar electrically connecting neighboring battery packs to each other; and a bus bar cover covering an end portion of the bus bar for insulating the bus bar, the bus bar cover including a hollow portion through which a coupling hole of the bus bar is exposed, the hollow portion extending in a direction away from the bus bar. According to embodiments, in the battery module, the bus bar electrically connecting different battery packs is sufficiently insulated to prevent malfunctions and safety accidents caused by a short circuit of the bus bar through which charging and discharging high-voltage current flows.

An electrical conductor comprising a flat conductor formed of a solid metallic material, the flat conductor having at least two opposite broad sides, two opposite narrow sides and two opposite end sides and having an at least quadrangular cross-sectional profile, and a flexible conductor formed of a plurality of strands, the strands of the flexible conductor being at least partially joined to one another in a materially bonded manner in the region of at least one end of the flexible conductor, characterized in that the flexible conductor, at its end with the joined strands, is joined in a materially bonded manner with its end face to an end face, a narrow side or broad side of the flat conductor.

A bus bar module includes a plurality of bus bars each having a through hole into which an electrode terminal of an electrode terminal group arranged in a line on a battery module formed of a plurality of battery cells is inserted, the bus bars being arranged along an arranging direction of the electrode terminal in the electrode terminal group, and a flat cable including a conductor part electrically connected to the bus bars, and an insulating holding part for holding the bus bars. The bus bar includes a holding body to be fitted to the flat cable. The holding part has a holding hole for each of the bus bars that allows a relative movement of the bus bar with respect to the flat cable in the arranging direction, by allowing a relative movement of the inserted holding body in the arranging direction.

A connector assembly for electrically connecting poles of two adjacent battery cell. The connector assembly comprises an electrically conductive bus bar having a first connection area and a second connection area distal from each other, electrically conductive pole-mating components having a pole-mating face and a bar-mating face, and fastening components for attaching the electrically conductive bus bar and one of the pole-mating components to one of the poles of the two adjacent battery cells. The pole-mating faces of the pole-mating components are adapted for mating the poles the battery cells. The bar-mating faces of the pole-mating components are adapted for mating with the connection areas. The bar-mating faces and the connection areas have complementary concave/convex arched shape for optimizing contact surface over a range of relative positioning of the two adjacent battery cells.

A connector (20) includes a connecting member (15) with a main body portion (16) for connecting adjacent electrode terminals (12A, 12B) of a plurality of battery cells (11) including positive and negative electrode terminals (12A, 12B) and a first terminal (22) extending from the main body portion (16), a battery-side connector housing (29) accommodating the first terminal (22), a wire-side connector housing (36) to be connected to the battery-side connector housing (29) and an end part of a wire (37, and a fuse (25) arranged in the battery-side connector housing (29) to electrically connect the first terminal (22) and the wire (37).

A bus bar for use in conducting an alternating current may comprise multiple substantially parallel ribs and an electrically conductive attachment feature. Each rib may include a first and second end. Each rib may be provided for conducting a substantially equal portion of the current. The ribs may be spaced apart to provide gaps therebetween for airflow through the gaps. The electrically conductive attachment feature may connect the first ends of the plurality of ribs, and may be provided for attaching the plurality of ribs to an electrical component. A method for manufacturing a bus bar for use in conducting an alternating current may comprise attaching a plurality of electrically conductive strips to form a bus bar having a plurality of ribs, each rib having a first and second end, the ribs spaced apart to provide gaps therebetween for airflow through the gaps, the first ends of the plurality of ribs connected together.

The present disclosure discloses a battery connection sheet, including: a first part, including a first metal sheet, a first buffer portion and a first connection portion, and a second part, including a second metal sheet connected with the first connection portion via electromagnetic pulse welding.

This patent pertains to magnetic coupling systems. One implementation includes magnetic jumper cables, which include magnetic couplers and elongate, insulated, electrically-isolated electric conductors.

A jumper cable which includes a receptacle mounted on, near or within a battery casing. The receptacle may include a socket having a pair of circular contacts on the inner circumference thereof electrically connected to battery terminals. The device may also include a cable having a plug on each end configured to mate with the receptacle socket. Such a plug may include a larger-diameter ring for engaging the upper contact and a smaller-diameter ring for engaging the lower contact when the plug is inserted into the socket, Accordingly, if a battery needs recharging, a plug is inserted into the receptacle associated with the dead battery and the opposing plug is inserted into a receptacle associated with a charged battery to establish electrical interconnection there between. Alternatively, an adapter having a socket and electrical clamps for grasping battery terminals may be used when a receptacle is not connected to one of the batteries.
