A cooling device for use with circuit interrupters includes a housing structured to be coupled to a terminal of the circuit interrupter and formed with several ventilation openings, as well as a permanent magnet, a torque converter and a fan blade all contained within the housing. When the cooling device is coupled to a terminal of a circuit interrupter and current flows through the terminals of the circuit interrupter, parasitic magnetic fields are generated and induce oscillatory motion of the permanent magnet. The torque converter is coupled to the permanent magnet and converts the oscillatory motion of the magnet to rotational motion that rotates the fan blade. The fan blade is disposed near the ventilation openings of the housing so that air flow produced by rotation of the fan blade travels across the surface of the circuit interrupter terminal nearest the ventilation openings to increase convection.

A battery system for an electric vehicle includes a fixed cover, and a removable cover arranged over battery modules and a high voltage distribution system. The battery system includes a busbar arranged at least partially over a region of the battery modules and under the removable cover. The busbar includes a fixed section and a movable section, or a hinge, such that the busbar can be repositioned out of the way. The support tray includes a link between the fixed and movable sections. Floating fasteners, allowing at least one of radial float and axial float are used to secure the link to the support tray, thereby avoiding safety hazards and reducing the potential for short circuits in high voltage distribution systems or conductors thereof. The floating fasteners include a head, a neck, an engagement section, and a washer, which prevent removal from a component once installed.

A system for detecting anomalies in electrical wiring in a truck trailer. The system measures and compares current drawn from the truck tractor with the current drawn by a circuit at a particular trailer component or other location in the trailer wiring. If the two current measurements differ in excess of a predetermined threshold, the system can report a wiring anomaly. The location of the anomaly can then be determined by performing the operation for different trailer components thus testing multiple different branches of the trailer power distribution circuit, and using the results of these tests to determine that an anomaly is present, and possibly the location of the issue. The system may then send a notification to a remote computing device, to the truck tractor, or any combination thereof.

A method of manufacturing a connector device suitable for making an inter or intra static electrical energy converter connection. The device includes at least two flat conductors and at least one insulating material. The said method includes: preparing each flat conductor individually; applying at least one coat of enamel varnish to each conductor, which is thinner than a desired final thickness; carrying out cross-linking of the enamel coating; and repeating the depositing of a layer of enameling resin and the cross-linking until the chosen thickness is reached. The varnish coated conductors of the connector device are assembled by using a template and connecting elements.
