Abstract: Thermal barrier assemblies are provided for inhibiting the transfer of thermal energy inside a traction battery pack. An exemplary thermal barrier assembly may include a structural barrier flanked by a pair of thermal resistance material layers. The structural barrier and the thermal resistance material layers may each include a non-uniform thickness. The structural barrier may include a reduced thickness at its respective outboard edges, and the thermal resistance layers may each include an increased thickness at their respective outboard edges. Providing a greater amount of thermal resistance material near the outboard edges of battery cells can help slow or even eliminate the transfer of thermal energy across a cell stack of the traction battery pack during a thermal event.

Abstract: A traction battery assembly includes an enclosure assembly having an interior area, and a pressure relief device having a valve member movable from a closed position to an unlocked-release position, and movable from the unlocked-release position to a locked-release position. The valve member in the closed position blocks flow through the pressure relief device from the interior area. The valve member in the unlocked-release position permits flow from the interior area. The valve member in the locked-release position permits flow from the interior area. A ratchet mechanism that holds the valve member in the locked-release position.

Abstract: Resealable guide tubes are provided for use within traction battery packs. One or more resealable guide tubes may be arranged such that a first portion of each guide tube extends inside an enclosure assembly of the traction battery pack and a second portion of each guide tube extends outside of the enclosure assembly. Each guide tube may be sized and shaped for guiding a measurement probe of a testing device directly to a high voltage measuring point located inside the traction battery pack. The testing device may then be utilized to measure one or more electrical properties associated with the traction battery pack.

Abstract: A vehicle charging includes a housing, a sensor system configured to detect if a vehicle is parked near the housing, and a notification system configured to communicate an alert if the vehicle is parked near the housing and charging has not been initiated within a threshold amount of time. The alert indicates improper usage of the vehicle charging station to an operator of the vehicle.
