Abstract: A battery includes a battery cell stack disposed within a housing such that a gap exists between the battery cell stack and an inner surface of the housing. The battery cell stack includes a plurality of battery cells that each include a positive electrode tab and a negative electrode tab electrically coupled to an electrode assembly and extending from the electrode assembly outside of a case. The positive electrode tabs and/or the negative electrode tabs of the plurality of battery cells extend into the gap between the battery cell stack and the inner surface of the housing. A filler material fills the gap and provides a thermally conductive pathway between the positive electrode tabs and/or the negative electrode tabs of the plurality of battery cells and the inner surface of the housing. The filler material includes a thermally conductive particulate component distributed throughout a polymeric matrix component.

Abstract: A heterogeneous multi-core system that executes a real-time system for an automobile includes a plurality of system-on chips in electronic communication with one another. Each system-on-chip includes a plurality of central processing units (CPUs) arranged into a plurality of logical domains. The heterogeneous multi-core system also includes a plurality of scheduled tasks that are executed based on an execution pipeline and each execute a specific set of tasks for one of the logical domains. The plurality of scheduled tasks includes at least one offset scheduled task that is executed at an offset time and a reference scheduled task located at an execution stage upstream in the execution pipeline relative to the offset scheduled task. The reference scheduled task communicates data to the offset scheduled task and the offset time represents a period of time measured relative to the reference scheduled task.
Abstract: In various embodiments, methods and systems are provided for processing data pertaining to a vehicle event for a vehicle. In accordance with an exemplary embodiment, vehicle sensor data is obtained from one or more vehicle sensors pertaining to the vehicle event. Also in an exemplary embodiment, an assessment of the vehicle event is determined via a processor, including as to a fault or a severity, or both associated with the vehicle event, based on the vehicle sensor data.
Abstract: A system for determining calibrated camera extrinsic parameters for an autonomous vehicle includes a camera mounted to the autonomous vehicle collecting image data including a plurality of image frames. The system also includes one or more automated driving controllers in electronic communication with the camera that executes instructions to determine a vehicle pose estimate based on position and movement of the autonomous vehicle by a localization algorithm. The one or more automated driving controllers determine the calibrated camera extrinsic parameters based on three dimensional coordinates for specific feature points of interests corresponding to two sequential image frames, the specific feature points of interests corresponding to the two sequential image frames, and the camera pose corresponding to the two sequential image frames.
Abstract: A quality control system analyzes the quality of a battery cell, with the battery cell defining a gas pouch configured to expand from a deflated configuration to an inflated configuration when filled with a gas formed during a cell formation process. The system comprises a computational system comprising a processor and a memory and a measurement instrument in electronic communication with the computational system. The measurement instrument is arranged to measure a distance defined by the gas pouch and transmit a signal to the computational system corresponding to the distance. The computational system is arranged to analyze the distance with the processor and determine a volumetric measurement of the gas within the gas pouch and compare the volumetric measurement to a threshold in the memory to assess a quality score for the battery cell. A corresponding method analyzes the quality of the battery cell with the quality control system.
