  • Publication number: 20250070351
    Abstract: A pressure management system includes a pressure plate disposed at an initial position relative to a battery cell, the battery cell disposed in a housing, the pressure plate and the housing defining an enclosure, where an increase in an internal pressure of the battery cell causes an expansion force to be applied to the pressure plate. The system includes a mechanical linkage attached to the pressure plate, the mechanical linkage configured to translate the expansion force to a reverse force that is opposed to the expansion force, and a rotatable component connected to the mechanical linkage, the rotatable component configured to rotate from a first orientation to a second orientation based on lateral movement of the mechanical linkage to allow the pressure plate to move and increase a volume of the enclosure.

  • Publication number: 20250045305
    Abstract: A method is disclosed for providing autocomplete suggestions for a navigation text box. The method includes receiving an input in the navigation text box and obtaining candidate navigation suggestions from a retrieval source. Respective signals are obtained for the candidate navigation suggestions, and respective probability scores are obtained by providing the input, candidate navigation suggestions, and signals to a navigation suggestion ranking model. The probability scores reflect a prediction of the likelihood of selection. Based on their respective probability scores, at least some candidate navigation suggestions are provided as autocomplete suggestions for the input. This method enhances user experience by offering relevant and personalized navigation suggestions in real-time, improving efficiency and accuracy in navigation tasks.

  • Publication number: 20250030039
    Abstract: A pressure management system includes a pressure plate configured to be disposed at an initial position relative to a battery cell in a housing, the initial position including a first orientation, a tilting assembly configured to allow the pressure plate to change from a first orientation to a second orientation based on the expansion force being non-uniform. The system includes a mechanical linkage attached to the pressure plate and configured to move laterally in response to the expansion force and translate the expansion force to a reactive force, and a biasing system including a biasing member configured to resist a lateral movement of the mechanical linkage. The biasing system is configured to apply a biasing force that causes the mechanical linkage to apply the reactive force, and based on the expansion force being non-uniform, is controllable to change the biasing force to balance an internal pressure of the cell.

  • Publication number: 20250030037
    Abstract: A vehicle includes an apparatus for performing a method of controlling a pressure within a battery. The battery is disclosed between a support plate at a first side of the battery and a pressure plate disposed at a second side of the battery opposite the first side. The pressure plate is movable with respect to the support plate to control the pressure of the battery and including a first plate wedge. The first actuator wedge is moved parallel to the pressure plate with the first actuator wedge in contact with the first plate wedge to control a force applied by the first actuator wedge to the first plate wedge to move the pressure plate with respect to the support plate. Moving the pressure plate controls the pressure within the battery.

  • Publication number: 20250023120
    Abstract: A vehicle includes a propulsion system having multiple electric motors. A battery system is connected to the electric motors via a direct current to direct current (DC-DC) converter and an inverter. The battery system includes a battery assembly having a plurality of battery modules. Each of the battery modules has multiple individual battery cells arranged in battery packs, a set of sensors configured to monitor a set of parameters of each battery pack, and a plurality of battery pack mounts. Each battery pack mount includes a base plate and a top plate and an actuator configured to alter a distance between plates. A monitoring unit is configured to monitor a value representative of a battery pack pressure, determine whether the value falls within a pressure threshold window, and maintain the value within the pressure threshold window by actively altering the battery pack pressure.
