  • Publication number: 20240136842
    Abstract: A battery charging system with enhanced time-based charging and coupling detection. A user provides a time available for charging to a control unit of the vehicle, a mobile device of the user, or a control unit of a charging station directly. In the case that the time available for charging is provided to the control unit of the vehicle or the mobile device of the user, this information is then shared with the control unit of the charging station when the control unit of the charging station detects coupling of the associated connector/coupler to the vehicle, or when the vehicle is detected within a predetermined proximity of the charging station. When the vehicle is connected to the charging station and charging commences, a standard charging power may be utilized or a charging power may be selected and utilized such that enhanced charging can be provided in the available time period.

  • Publication number: 20240136945
    Abstract: Described herein are controllers configured for a wireless power system and methods for such controllers and systems. The controller includes a control module configured to generate a first control signal having a first voltage level and a second control signal having a second voltage level and a modulator configured to (a) receive a signal representative of the output current and (b) generate carrier signals based on the output current. When a first carrier signal is greater than the first voltage level, a first gate drive signal for a first switch is high and when a second carrier signal is greater than the second voltage level, a second gate drive signal for a second switch is high, thereby driving an inverter to output a multi-level voltage having a first output level based on the first drive signal and a second output level based on the second drive signal.

  • Publication number: 20240132297
    Abstract: A sorting system conveys a heterogeneous mixture of material pieces past an XRF system and a vision system. A classification of a material piece is changed to a high copper content aluminum alloy when the XRF system classifies the material piece as a low copper content aluminum alloy and the vision system determines that the material piece is a thin strip material piece. The reclassified material piece is then sorted accordingly.

  • Publication number: 20240132026
    Abstract: A battery module with removable cells and a battery management system or charging station system that determines the number of cells to use for a given trip. Thus, the system receives trip information (starting point, destination, stops, etc.) and determines the number of cells required for the trip, optionally based on traffic conditions, weather, prior driving habits, cell state of charge (SOC), cell state of health (SOH), and the like. The system can recommend which cells to leave in the vehicle, which cells to remove from the vehicle, which cells to place in the vehicle, which cells to charge, and the like, via a visual indicator. Importantly, a number of cells actually required for the trip can be suggested, without extra cells, such that extra weight in terms of unused cells may be removed from the vehicle, thereby increasing trip efficiency.

  • Publication number: 20240131828
    Abstract: Articles and devices comprising fluorinated polymers, as well as methods of preparing fluorinated polymers, are generally described. In some cases, such fluorinated elastomers can be used for sensing neural activity, e.g., by encapsulating electronic circuits, or other applications. Furthermore, according to certain embodiments, polymers can, surprisingly, be directly deposited onto layers comprising low molecular weight fluorinated polymers, e.g., without swelling in the presence of certain solvents. Some embodiments are generally directed to devices and methods for treating fluorinated polymers and subsequently depositing material onto the treated fluorinated polymers. This may allow the fabrication and patterning of multilayered articles comprising fluorinated elastomers.

  • Publication number: 20240131948
    Abstract: A battery charging system with enhanced time-based charging, which may be static or dynamic. A user provides a time available for charging a vehicle to a control unit of the vehicle, a mobile device of the user, or a control unit of a charging station directly. In any case, this information is received by the control unit of the charging station via a wired connection, a wireless connection, a near field connection, a cloud network, or directly. When the vehicle is connected to the charging station and charging commences, a charging power is selected and utilized such that enhanced charging can be provided in the available time period, illustratively providing as much charge as possible in the available time period. This charging power may be modified responsive to user changes to the available charging time while charging is ongoing.

  • Publication number: 20240131949
    Abstract: A battery charging system with enhanced time-based charging and coupling detection, as well as battery health monitoring and battery cell selection. A user provides a time available for charging to the vehicle or a mobile device and indirectly to a charging station, or the charging station directly. The time available for charging, as well as battery health information, is shared with the charging station when the charging station detects coupling of the associated connector/coupler to the vehicle, or when the vehicle is detected within a predetermined proximity of the charging station. Subsequently, a standard charging power may be utilized or a charging power may be selected and utilized such that enhanced or optimized charging can be provided for the available time period. A battery control unit identifies degraded or faulted battery cells and charging of these battery cells is avoided or deprioritized.

  • Publication number: 20240131959
    Abstract: A battery system that, based upon the state of charge (SOC), state of health (SOH), and discharge profile of a battery module, or removable cells of the battery module, apprises the user of optimal or allowable storage temperature and time before the charge and range of a fully charged battery module or removable cell is degraded. In the event that this optimal or allowable storage temperature or time is deviated from or exceeded, the battery system recalculates the necessary charging power and time to meet the original range calculation and satisfy original trip requirements. This may be utilized for cells stored both in the vehicle and cells stored remote from the vehicle.

  • Publication number: 20240131958
    Abstract: A battery system that collects and considers multiple variables to provide optimal charge and range information, either on a battery module or per cell basis. This system may provide the required charge time to complete a trip and provides a minimum SOC, which may be achieved by charging or via cell swapping. Variables considered may include expected traffic conditions for a trip, expected temperature for a trip, expected wind conditions for the trip, expected trip topography, etc., all gathered prior to the start of and/or updated during the trip. Based on this smart range estimation, the system can provide the cell swaps required, the number cells to charge, the expected charging time required, and alert the user if charge/swap related stops will be required during the trip in order to successfully complete the trip.
