Abstract: A system for evaluating a battery cell includes an imaging device configured to take a first image of at least part of the battery cell when the battery cell is in a first deformation state, and take a second image of the at least part of the battery cell when the battery cell is in a second deformation state. The system also includes a processor configured to analyze the first image and the second image, identify a first region of the first image that represents a suspected discontinuity, the first region corresponding to a portion of the battery cell, compare the first region of the first image to a second region of the second image, the second region corresponding to the portion of the battery cell, and determine that the suspected discontinuity is an actual discontinuity based on a difference between the first region and the second region.

Abstract: Presented are clutch-type engine disconnect devices, methods for making/using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device includes a notch plate, which has multiple notches and attaches to a torque converter, and a pocket plate, which has multiple pockets and attaches to an engine's crankshaft. A pawl is movably mounted within each notch; these pawls selectively engage the notches with the pockets. A notch plate insert is nested within each notch, supporting thereon one of the pawls. A selector plate interposed between the pocket and notch plates moves from a first position, to shift the pawls out of engagement with the pockets, and a second position, to move the notch plate inserts within the notches and allow the pawls to engage the notches with the pockets to thereby lock the notch plate to the pocket plate to rotate in unison with each other.

Abstract: Presented are dual-clutch engine disconnect devices, methods for making/using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device for a vehicle includes a first one-way clutch (OWC) with concentric inner and outer races and torque elements interposed between and transferring torque across these races in a first direction. The first outer race rigidly attaches to a damper plate for common rotation therewith, and the first inner race rigidly attaches to a pump cover of a torque converter for common rotation therewith. A second OWC, which concentrically aligns within the first OWC, includes concentric inner and outer races with torque elements interposed between and transferring torque across these races in a second direction. The second outer race is splined to the first inner race for common rotation with the pump cover. The second inner race rigidly attaches to the damper plate for common rotation therewith.

Abstract: The continuously variable transmission (CVT) assembly includes a CVT including a drive pulley, a driven pulley, and an endless rotatable device coupled between the drive pulley and the driven pulley. The CVT assembly also includes an actuator coupled to the drive pulley. The CVT assembly also includes an angle sensor coupled to the endless rotatable device such that the angle sensor is configured to measure an angular position of the endless rotatable device. The CVT assembly also includes a controller in communication with the actuator and the angle sensor. The controller is programmed to: (a) determine a speed ratio of the CVT based on the angular position of the endless rotatable device; and (b) control the actuator to adjust the clamping force exerted on the drive pulley in response to determining the speed ratio of the CVT.

Abstract: A system for evaluating a battery cell includes an imaging device configured to take an image of at least part of the battery cell, and a processor. The processor is configured to perform: determining a region of interest in the acquired image, reducing a sharpness of the acquired image to generate a reference image, comparing the acquired image and the reference image, and identifying a discontinuity of the battery cell based on a difference between the acquired image and the reference image.

Abstract: Aspects of the disclosure include degas equipment and degassing process schemes for providing high throughput extraction of battery cell formation gas. An exemplary method can include loading a battery cell in a sampling chamber of a degas station and creating an opening in the battery cell to release formation gas. A first portion of the formation gas can be routed to a collection chamber of the degas station while the formation gas is prevented from venting. After routing the first portion of the formation gas to the collection chamber, a second portion of the formation gas can be vented until degassing is complete. The first portion of the formation gas can be diluted with a dilution fluid and the diluted first portion of the formation gas can be routed to a cell quality control gas manifold configured to measure battery cell formation gas compositions.

Abstract: A quality control system analyzes the quality of a battery cell, with the battery cell defining a gas pouch configured to be filled with a gas. The quality control system includes a computational system including a processor and a memory, a manifold defining a passageway extending between an inlet port for receiving the gas and an outlet port, and at least one sensor in electronic communication with the computational system. The sensor is arranged to measure a physical property of the gas and transmit a signal to the computational system corresponding to the physical property of the gas. The computational system analyzes the physical property of the gas, accesses a threshold value corresponding to the physical property, compares the physical property to the threshold value, and assess a quality score for the battery cell. A corresponding method analyzes the quality of the battery cell with the quality control system.
