An electrical assembly includes an electrical conductor having a planar portion and defining a bore hole extending through the planar portion and an electrical contact having a tubular portion disposed within the bore hole and a plurality of contact petals extending radially from the tubular portion. The plurality of contact petals are in electrical contact with the electrical conductor. A method of producing such an electrical assembly is also provided.

Disclosed is a pole socket for an energy storage system, having a connecting element with a first end region and with a second end region, a connection element which is arranged on the first end region and which is configured to make electrical contact with electrical consumers, and a contacting element which is arranged on the second end region of the connecting element and which is configured to make electrical contact with a pole shaft. The connection element extends in a first direction of extent proceeding from the connecting element, and wherein the contacting element extends in a second direction of extent proceeding from the connecting element. The second direction of extent runs parallel and in the opposite direction with respect to the first direction of extent, such that the contacting element is arranged offset from the connection element.

An exemplary array activating assembly includes, among other things a disconnect key moveable back and forth between an engaged and a disengaged position relative to a battery array. The disconnect key completes an electrical conductive path of the battery array when in the engaged position. The electrical conductive path is open when the disconnect key is in the disengaged position. An exemplary array activating method includes moving a disconnect key relative to a battery array from a disengaged to an engaged position. The disconnect key completes an electrical conductive path of the battery array when in the engaged position. The disconnect key does not complete the electrical conductive path when in the disengaged position.

An embodiment is directed to a module-to-module power connector configured to form connections between battery modules installed in a battery housing of an energy storage system. The module-to-module power connector includes electrical interfaces and busbar(s) configured to form one or more electrical connections terminals of adjacent battery modules. The busbar(s) is flexibly configured to permit a defined range of movement of the electrical interfaces during insertion of the respective battery modules into respective battery module compartments. The module-to-module power connector may further be arranged inside in a tunnel space, whereby holes are defined in a battery module mounting area housing the battery modules that open into the tunnel space.

The present disclosure relates to the field of energy storage devices and in particular, to a housing used for a battery pack and a battery pack. The housing includes a main body and an installation panel. The main body includes a battery accommodation space and a panel installation window communicating with the battery accommodation space, and the battery accommodation space is configured to accommodate a battery. The installation panel and the main body are separately formed, and the installation panel is installed at the panel installation window. The installation panel includes a base and a connection device installation portion connected to the base, and the connection device installation portion is where a connection device that is connected to the battery is to be installed. The housing provided by the present disclosure has a relatively low production cost and a relatively high production efficiency.

An electrical cable is provided with a rounded insulated electrical conductor that transitions to a flattened section to fit into areas where the rounded portion does not fit. A round electrical conductor transitions to a flattened section for electrical conduction routing via the undercarriage of a vehicle, for routing under the carpeting of the passenger compartment, or other confined spaces. The electrical cable may illustratively be used in an electric car application where distribution of electrical current from the battery compartment to the motor requires additional wiring in the vehicle not found in combustion based engines. The reduced vertical profile of the flattened section provides for additional clearance between the vehicle undercarriage and the road, or between the undercarriage frame and the interior passenger compartment carpet.

A battery terminal adapter providing support for a plurality of wires, allowing several wires to be connected simultaneously and in parallel to a single, threaded battery electrode or terminal, such as a positive or negative threaded electrode of a vehicle battery. For this purpose, the battery terminal adapter includes an adapter body having a threaded battery terminal receiving cavity, two or more wire-receiving holes and two or more fastener bores in spatial communication with a respective one of the wire-receiving holes. The wire-receiving holes are in electrical communication with the battery terminal receiving cavity so that all electrical wires connected to the wire-receiving holes are powered by the battery.

A protector includes a plurality of lead-out openings through which electric cables are configured to be led out, and an electric cable attachment part which is provided in a projecting manner at an opening edge part of the lead-out opening and to which the electric cables are configured to be attached through a hinge part with flexibility. The electric cable attachment part is bent toward the lead-out opening by the hinge part, and a bent state thereof is configured to be held by a holding part.

A clamp for a male terminal of a power source, consisting of a frustoconical body projecting out of a base surface that is part of the source against which it rests with its greatest diameter. The clamp comprises at least one first ring-shaped portion with an open section of its circumference. Said first ring-shaped portion has such a diameter that a predetermined radial clearance exists when it axially fits upon said frustoconical body, and also has two jaws which axially project out of its circumference and are located at the ends of the open section of the circumference. The jaws are in opposed, spaced-apart relationship and a device is adapted to cause them to move toward each other to clamp the ring-shaped portion around the frustoconical body, by eliminating the radial clearance. The clamp comprises at least one first plate-like element associated with said ring-shaped portion of the clamp on the side on which it is inserted onto the frustoconical body of the male terminal, which is made of an electrically non-conductive material and has a through hole whose diameter is adapted to create a radial interference with the diameter of the frustoconical body of the male terminal proximate to said base surface from which it protrudes.
