Namely, examples leverage an intelligent insight that many types of vehicle tamper events have unique audio signatures. Accordingly, examples detect/classify vehicle tamper events based on these unique audio signatures. Moreover, examples can verify these audio-based classifications by analyzing acceleration-related data (e.g., relative acceleration data for a body of a vehicle, relative jerk data for a body of a vehicle, etc.) to determine suspicious movement of a body of a vehicle during a potential/suspected vehicle tamper event. This acceleration-related verification step can reduce occurrence of false positive audio-based classifications caused by other noise events proximate to the vehicle that have similar audio signatures to vehicle tamper events (e.g., drilling or other noise from a construction site, rain, etc.).

THERMAL BARRIER BULB SEALS FOR ESTABLISHING SEALING INTERFACES WITHIN TRACTION BATTERY PACKS
Battery cell stack designs are provided for traction battery packs. An exemplary cell stack may include a thermal barrier assembly that is arranged to inhibit the transfer of thermal energy between adjacent subgroupings of battery cells of the cell stack. The thermal barrier assembly may include a bulb seal for sealing an interface between the thermal barrier assembly and a perimeter environment (e.g., a heat exchanger plate, an enclosure tray, etc.). The bulb seal may seal any leak paths between the thermal barrier assembly and the perimeter environment, thereby preventing vent gases from passing from one battery cell subgrouping to another during battery thermal events.

A method of assembling a battery pack includes positioning one or more terminals of a cell stack within a slot that is provided by a frame of a cross-member assembly. The method further includes securing a beam of the cross-member assembly to the frame after the positioning. The beam can be a pultruded beam that covers several slots of the frame.

TRACTION BATTERY PACK TERMINAL CLAMP AND CLAMPING METHOD
A method of assembling a battery pack includes inserting at least one terminal through a slot of a cross-member assembly, folding the at least one terminal over a busbar of the cross-member assembly, pressing the at least one terminal against the busbar using a clamping fixture, and securing the at least one terminal to the busbar through at least one aperture in the clamping fixture.
A traction battery pack system includes one or more busbars protruding from a battery array of a traction battery pack, and a control module assembly that slidably receives the one or more busbars to electrically couple the control module assembly to the one or more busbars. The control module assembly can be a bussed electrical center.

A method of assembling a battery pack includes inserting a guide within a slot of a slotted assembly; guiding one or more terminals into the slot using the guide; and withdrawing the guide from the slot while the one or more terminals remain in the slot. A traction battery pack assembly includes a terminal guide; and an actuator assembly that rotates the terminal guide back and forth between a guiding position and a withdrawn position. The terminal guide is at least partially disposed within a slot of a slotted assembly when in the guiding position such that the terminal guide can guide insertion of one or more terminals into the slot. The terminal guide is withdrawn from the slot when in the withdrawn position.

Multi-functional barrier trays are provided for use within traction battery packs. An exemplary barrier tray may be arranged between a heat exchanger plate and a cell stack of the traction battery pack for maintaining electrical isolation between battery cells of the cell stack and the heat exchanger plate, providing flat surfaces for cell stack thermal barrier and end plate components to interface relative to, and sealing interfaces between the cell stack and the heat exchanger plate.
