Abstract: Systems and methods of controlling an active safety feature of a vehicle are provided. The systems and methods receive radar data from a radar device of the vehicle and image data from a camera of the vehicle. Object detection and tracking processes are performed on the radar data and the image data to identify and track objects in an environment of the vehicle. Conditions are assessed with respect to identified objects to ascertain whether a radar track is erroneously reported as a separate object to a camera track. When the conditions are assessed to be true, an object corresponding to the camera track is used as an input for controlling an active safety feature of the vehicle and an object corresponding to the radar track is discounted for controlling the active safety feature of the vehicle.

Abstract: Excessive expansion of rechargeable batteries during recharging is a significant concern since the uncontrolled buildup of high internal battery pressures from expansion inside a confined space can lead to separator membrane failure and/or thermal runaway of a battery cell. A crushable foam or honeycomb insert layer is placed inside of a rigid battery fixture to automatically limit the progressive buildup of internal battery pressure due to charging-induced expansion of the battery cell during recharging. The crushable insert layer is included as part of the rigid battery fixture. Aluminum honeycomb cores and porous aluminum metal foam materials have a significant amount of crushability over a very wide range of compressive strains. Alternatively, a porous metal foam or metal honeycomb material may be infused with a liquid polymer (e.g., silicone, rubber, EDPM, or polyurethane) to enhance the mechanical properties of the polymer-infused metal foam or honeycomb metal/polymer composite material.

Abstract: A method of making a reference electrode assembly for an electrochemical cell according to various aspects of the present disclosure includes providing a subassembly including a separator layer and a current collector layer coupled to the separator layer. The method further includes providing an electrode ink including an electroactive material, a binder, and a solvent. The method further includes creating a reference electrode precursor by applying an electroactive precursor layer to the current collector layer. The electroactive precursor layer covers greater than or equal to about 90% of a superficial surface area of a surface of the current collector layer. The electroactive precursor layer includes the electrode ink. The method further includes creating the reference electrode assembly by drying the electroactive precursor layer to remove at least a portion of the solvent, thereby forming an electroactive layer. The electroactive layer is solid and porous.

Abstract: A mechanical design of a rechargeable battery cell (e.g., a Lithium-ion battery) disposed inside of a prismatic can, for use in electric vehicles and other electric-powered devices. The improved design uses a thermally conductive insert to divide the battery cell into two adjacent volumes that each hold a pair of stacked layers of a battery cell. This thermally conductive insert conducts heat from the center of the battery cell during battery recharging to actively-cooled channels disposed in a pair of cooling manifolds that are disposed on two vertical sides of the battery cell. Alternatively, or additionally, an actively-cooled bottom cold plate can be used. The pair of stacked battery layers can each be wound in a “jelly-roll” geometric configuration. The thermally conductive insert may be made of aluminum, aluminum alloy, copper, or copper alloy, and combinations thereof.

Abstract: Systems and methods associated with an electric vehicle are provided. The electric vehicle includes a sensor system, a communications system and a snow clearing system. The systems and methods detect, based on data from the sensor system, snow that may accumulate on a window of the electric vehicle. When snow is detected, a notification is provided, via the communications system, to a remote user device. The notification requests user acceptance of use of charge of a battery of the electric vehicle to operate the snow clearing system of the electric vehicle. The systems and methods receive, by the communications system, a response to the notification from the user device, and when the response indicates acceptance of the use of charge of the battery, the snow clearing system is activated. The snow clearing system is powered by the battery.

Abstract: A system for 5G MICO mode operation of a vehicle during an ignition off mode includes a telematics unit and a telematics communication mode controller. The controller monitors energy consumption by the telematics unit and estimates a total energy consumption of the telematics unit through a time period. The controller further compares the total energy consumption to a first threshold energy consumption and a second threshold energy consumption and, when the total energy consumption is less than the first threshold energy consumption, operates the telematics unit in a first mode including unrestricted communication. The telematics communication mode controller, when the total energy consumption is between the first threshold energy consumption and the second threshold energy consumption, operates the telematics unit in a second MICO mode and, when the total energy consumption is greater than the second threshold energy consumption, deactivates communications by the telematics unit.
