    Abstract: A solid-state battery module includes a housing, a pre-compressed solid-state battery cell stack disposed within the housing, and first and second opposed interior surfaces facing and compressing the pre-compressed solid-state battery cell stack therebetween. At least one of the first and second interior surfaces is curved and configured to increase compression in a low pressure central area of the pre-compressed solid-state battery cell stack to facilitate providing an even distribution of pressure across the pre-compressed solid-state battery cell stack.

    Abstract: A fuel cell electric vehicle (FCEV) includes an electric drive motor, a hydrogen fuel cell, an on-board hydrogen storage tank, a portable hydrogen storage cartridge, a controller, a battery pack and a plug interface having a vehicle charging inlet. The electric drive motor delivers drive torque to at least one drive wheel. The on-board hydrogen storage tank is configured to store hydrogen and selectively supply the hydrogen to the fuel cell in a first operating mode. The portable hydrogen storage cartridge selectively connects to a hydrogen portable interface configured on the FCEV. The portable hydrogen storage cartridge supplies the hydrogen to the fuel cell in a second operating mode. The controller determines whether hydrogen from the on-board hydrogen storage tank is supplied to the fuel cell in a first operating mode or hydrogen from the portable hydrogen cartridge is supplied to the fuel cell in the second operating mode.

    Abstract: A vehicle access system for a vehicle includes a telematics device disposed on the vehicle for communication with a portable electronic device via a network, the portable electronic device associated with the vehicle and configured to generate first and second security keys, and generate and display a QR code mapped from the first security key, the QR code configured to be authenticated by the second security key. An imaging device is disposed on the vehicle, and a vehicle controller is in signal communication with the telematics device and the imaging device. The vehicle controller is configured to perform operations including receiving the second security key to begin execution of an authentication process, detecting, with the imaging device, the QR code generated with the first security key, authenticating the QR code with the second security key, and upon authenticating the QR code, enabling access to a vehicle function.

    Abstract: A regenerative braking system for an electrified vehicle includes a battery system, an electric motor and a regenerative system resistor. The battery system selectively stores and delivers power. The electric motor is powered by the battery system and transfers drive torque to a driveline for propulsion of the vehicle and that selectively directs regenerative power in a first mode to the battery system during regenerative braking. The regenerative system resistor is selectively moveable between a first position during the regenerative braking in the first mode and a second position where regenerative power is directed to the regenerative system resistor and dissipated as heat in a second mode. At least one fan is disposed on the regenerative system resistor and selectively operates to direct air onto the regenerative system resistor based on operating conditions.

    Abstract: An electric drive module (EDM) that generates and transfers drive torque to a driveline of an electrified vehicle is provided. The EDM includes an electric drive gearbox assembly having a housing, first and second planetary gear sets, and a damper. The housing defines a first and second pockets and an annular channel formed intermediate an outer wall of the housing and a ring gear support inner wall. The first planetary gear set is disposed in the first pocket and has a first ring gear splined to the ring gear support inner wall. The damper is disposed in the annular channel and has an inboard surface that engages a damper engaging surface on the ring gear support inner wall and an outboard surface that engages the housing outer wall. The damper mitigates noise vibration and harshness (NVH) of the electric drive gearbox assembly.

    Abstract: An engine system includes an internal combustion engine, a main exhaust aftertreatment system with a main catalytic converter, and a light-off catalyst bypass system with a bypass passage and a bypass catalytic converter. An emissions control system includes a controller in signal communication with an oxygen sensor disposed downstream of the bypass catalytic converter. The emissions control system performs a diagnostic of the bypass catalytic converter, by the controller, including (i) monitoring signals from the downstream oxygen sensor for a predetermined time period during an engine cold start condition, (ii) determining a curve plotting oxygen content at the downstream oxygen sensor over the predetermined time period, based on the signals from the downstream oxygen sensor, (iii) determining a number of times the curve crosses a predetermined setpoint over the predetermined time period, and (iv) comparing the number to a predetermined threshold to determine if the bypass catalytic converter has failed.
