  • Patent number: 11946515
    Abstract: A method for determining, in real-time, an electronic limited-slip differential (eLSD) clutch torque includes receiving vehicle data in real-time, wherein the vehicle data includes a torque request, determining a preliminary eLSD clutch torque using a neural network and the vehicle data, determining clutch torque bounds of the eLSD using a physics-based model, determining whether the preliminary eLSD clutch torque is outside the clutch torque bounds of the eLSD, adjusting the preliminary eLSD clutch torque using clutch torque bounds to determine a final clutch torque of the eLSD in response to determining that the preliminary eLSD clutch torque is outside the clutch torque bounds of the eLSD, and commanding, in real-time, the eLSD to apply the final clutch torque to a clutch of the eLSD.

  • Patent number: 11946432
    Abstract: A throttle body for an engine or fuel cell of a vehicle is provided. The throttle body comprises a cylindrical housing comprising a first open end extending to a second open end defining an inner wall having an inner surface. The throttle body further comprises a moveable blade valve movably disposed on the inner wall and arranged to regulate air to the engine during operation of the vehicle. The moveable blade valve has an outer surface. The throttle body further comprises a dual-phase thermal composite coating (TCC) disposed on one of the inner surface of the inner wall and outer surface of the moveable blade valve for enhanced thermal conductivity and reduced deposit accumulation on the inner surface and the outer surface. The dual-phase TCC comprises a first material comprising between 10 wt % and 90 wt %, and a second material comprising between 10 wt % and 90 wt % of the dual-phase TCC. The dual phase TCC has a contact angle of between 100° and 160° and a thermal conductivity of at least 0.3 W/mK.

  • Publication number: 20240106067
    Abstract: A battery pack includes an elongated exhaust conduit defining a gas flow channel. The exhaust conduit includes a longitudinal center axis and a terminal end having a pack vent. The battery pack also includes fins disposed within the gas flow channel, and a plurality of battery cells arranged adjacent to the exhaust conduit. Each respective battery cell includes an outer casing defining a cell cavity. The casing defines a cell vent opening. An anode and a cathode are disposed within the cell cavity, and a vent cap covers the cell vent opening. The vent cap opens at a predetermined pressure to release hot gasses from the cell cavity into the gas flow channel. The fins direct the hot gasses along the longitudinal center axis and toward the terminal end of the exhaust conduit, and thus to the pack vent for discharge to the surrounding ambient environment.

  • Publication number: 20240106259
    Abstract: A power-densifying charging station includes a low-power charging module (LPCM), a direct current (DC) storage device, electrical switches, and a controller. The LPCM receives a low-power input voltage from a low-power energy source. The DC storage device accumulates a high-power DC voltage from the low-power input voltage during a charge accumulation stage of operation. The switches selectively connect the charging station to the energy source, the LPCM to the DC storage device, and the DC storage device to a high-voltage offboard battery pack during a charge delivery stage of operation. The controller is in communication with and operable for controlling the LPCM, the DC storage device, and the switches during the charge accumulation and delivery stages of operation via performance of a corresponding method.

  • Publication number: 20240100990
    Abstract: A method, system, and motor vehicle for controlling a direct-current fast-charging process of a battery system are provided that significantly improves performance of the direct-current fast-charging process and minimizes condensation issues by utilizing lower coolant temperature for a short duration when a rechargeable energy storage system cell temperature is greater than a specific temperature threshold. The rechargeable energy storage system cell temperature, a rechargeable energy storage system state of charge a rechargeable energy storage system voltage, and a rechargeable energy storage system direct-current fast-charging current are utilized to determine when to utilize the lower coolant temperature when the rechargeable energy storage system cell temperature is greater than a specific temperature threshold instead of using a lower coolant temperature from the beginning of the direct-current fast-charging process.

  • Publication number: 20240106072
    Abstract: A bicontinuous separating layer include a separating matrix having pores and a solid-state electrolyte disposed in the pores of the separating matrix. In certain variations, the bicontinuous separating layer is prepared by contacting a solid-state electrolyte liquid-state precursor with the separating matrix and heating the infiltrated separating matrix to a temperature between about 25° C. and about 300° C. The solid-state electrolyte liquid-state precursor includes a solvent and a solid-state electrolyte powder or a solid-state electrolyte precursor. In other variations, the bicontinuous separating layer may be prepared by contacting a solid-state electrolyte powder with a separating matrix to form a physical mixture and heating the physical mixture to a temperature between about 240° C. and about 500° C., where the separating matrix is defined by a polymer having a melting temperature greater than about 215° C., and the solid-state electrolyte has a melting temperature greater than about 300° C.
