A structural assembly includes a frame and a plurality of panels. The frame includes a wall that at least partially defines an interior region. The plurality of panels is disposed at least partially in the interior region and is coupled to the frame. The plurality of panels includes a first panel and a second panel. The first panel includes a first surface and a second surface opposite the first surface. The first surface defines a first plurality of depressions and the second surface defines a first plurality of protrusions complementary to the first plurality of depressions. The second panel includes a third surface and a fourth surface opposite the third surface. The third surface defines a second plurality of depressions. The fourth surface defines a second plurality of protrusions complementary to the first plurality of depressions. The first panel is coupled to the second panel.

An electrical connection unit for a battery pack includes a busbar having a first hole therein, a top surface and a bottom surface, an annular bushing having a top end abutting the bottom surface, a bottom end opposed to the top end and a bore hole therein registered with the first hole, a busbar cage secured to the busbar and retaining the annular bushing in abutment with the busbar, the busbar cage having a cavity therein above the top surface, and a fastener having a head portion captured within the cavity and a shank portion extending through the first hole. The annular bushing may include one or more indents formed on an outer surface thereof, and the busbar cage may include a plurality of fingers extending along the outer surface and interfacing with the one or more indents. Each finger may include a protrusion configured to rest within an indent.

Presented are thermomechanical fuses for mitigating heat propagation across electrochemical devices, methods for making and methods for using such fuses, and traction battery packs with load-bearing, sacrificial thermomechanical fuses to help prevent thermal runaway conditions. A battery assembly includes an electrically insulating battery housing with multiple battery cells disposed inside the battery housing. These battery cells are electrically interconnected, in series or parallel, and stacked in side-by-side facing relation to form adjacent, mutually parallel stacks of battery cells. Thermomechanical fuses thermally connect neighboring stacks of the battery cells. Each thermomechanical fuse is formed, in whole or in part, from a dielectric material that undergoes deterioration or deformation at a predefined critical temperature; in so doing, the thermomechanical fuse thermally disconnects a first stack of cells from a neighboring second stack of cells.

A pre-assembled electrical connection unit for a battery pack includes a bus bar defining a hole, and a cage defines a cavity. The unit also includes a fastener disposed in the cavity and the cage surrounds the fastener. The cage is secured to the bus bar, and the fastener is positioned in the hole and the cavity in an initial position. The fastener is movable to a final position relative to the cage which positions the fastener deeper in the hole of the bus bar. The unit is positioned relative to the battery pack, and the battery pack includes a module terminal. The module terminal includes a terminal nut that is accessible during an assembly process. The unit is placed over the terminal nut during the assembly process such that the fastener aligns with the terminal nut and secures the bus bar to the module terminal in the final position.

A destination selection system for determining travel destinations includes a human-machine interface (HMI); a positioning system in communication with the HMI; a controller in communication with the HMI and the positioning system, the controller having a processor, and a memory, the processor executing programmatic logic stored in the memory. The programmatic logic includes a first logic to display an icon on the HMI based on position data received from the positioning system; and a second logic for sizing the icon based on at least one of the position data and one or more additional factors, and in response to at least one of the position data and one or more additional factors actively and continuously resizing the icon.
