Abstract: A control system to prevent thermal runaway includes an enclosure housing a plurality of battery cells of a battery module. Each of the battery cells is a pouch-type battery cell includes a core and a pouch enclosing the core and including one or more portions along one or more side surfaces thereof that are attached together by adhesive to form a seal. The adhesive is configured to release the seal when pressure within the pouch exceeds a predetermine pressure value. A gas sensor is configured to sense a predetermined gas in the enclosure. A valve is configured to selectively deliver thermal control fluid from a source. A controller is configured to open the valve in response to the gas sensor sensing the predetermined gas in the enclosure.

Abstract: In an exemplary embodiment, a LiDAR is provided that is configured for installation in a mobile platform. The LiDAR includes a scanner and a light-intensity receiver. The scanner includes a light source configured to direct illumination in an illuminating direction. The light-intensity receiver includes one or more light-intensity sensors; and one or more lens assemblies configured with respect to the one or more light-intensity sensors, such that that at least one sensor plane from the one or more light-intensity sensors is tilted to form a non-zero angle with at least one equivalent lens plane from the one or more lens assemblies, transferring the sensor focal plane to be align with the main light illumination direction and be consistent with the direction of movement of a mobile platform.

Abstract: A vehicle includes an engine having a combustion cylinder, and at least one fuel injector configured to supply a number of fuel pulse to the cylinder. A controller is programmed to issue a first fuel pulse command to actuate the fuel injector allowing fuel to pass through the fuel injector as a first fuel mass. The controller is also programmed to monitor a voltage across the fuel injector, and determine a preliminary fuel injector opening magnitude based on a rate of change of voltage. The controller is further programmed to assign the preliminary fuel injector opening magnitude as a maximum fuel injector opening magnitude in response to the first fuel mass being greater than a quantity threshold. The controller is further programmed to apply a scaling factor to adjust a second fuel pulse command to normalize the maximum fuel injector opening magnitude value to a predetermined full open value.

Abstract: Battery systems including battery cells and hydrogen-permeable membranes are provided. In one example, a battery system includes a battery cell. The battery cell includes a cell enclosure disposed about a cell interior. At least one multi-layer stack is disposed in the cell interior and includes a cathode, an anode and a separator disposed therebetween. A hydrogen-permeable membrane is in fluid communication with the cell interior and is configured to selectively allow any hydrogen produced in the battery cell to pass from the cell interior through the hydrogen-permeable membrane to outside of the battery cell while substantially preventing other fluids from passing through the hydrogen-permeable membrane.

Abstract: A method for predicting a rotor temperature of an electric motor for an electric vehicle. The method includes measuring at least one of an operating parameter of the electric motor; inputting the at least one of the operating parameter of the electric motor into a predetermined regression model to predict a rotor temperature of the electric motor; and communicating the rotor temperature of the electric motor to a vehicle control module for managing the electric motor. The operating parameters includes a measured stator temperature, a torque level output, a rotor speed, and a coolant flowrate of the fixture electric motor. The electric motor may be that of an induction motor.
