  • Publication number: 20190030867
    Abstract: Treatments are provided to strengthen adhesion of an optical filter layer in a photovoltaic (PV) module to an encapsulant layer, or generally, between inorganic materials and organic polymers. The embodiments disclosed herein can provide five or more times the adhesive forces of untreated encapsulant-filter interfaces. As a result, the system can enhance long-term reliability of PV modules by reducing interface surface charges and dangling bonds and reducing gaps and cracks, thereby preventing moisture, impurities, and particles from entering the interface. The treated optical filter layer can result in a surface modification. In some embodiments, treating the optical filter layer includes applying a chemical treatment such as an acid or alkaline wash, and/or ultrasonic cleaning.

  • Patent number: 10193467
    Abstract: We describe a power conditioning unit with maximum power point tracking (MPPT) for a dc power source, in particular a photovoltaic panel. A power injection control block has a sense input coupled to an energy storage capacitor on a dc link and controls a dc-to-ac converter to control the injected mains power. The power injection control block tracks the maximum power point by measuring a signal on the dc link which depends on the power drawn from the dc power source, and thus there is no need to measure the dc voltage and current from the dc source. In embodiments the signal is a ripple voltage level and the power injection control block controls an amplitude of an ac current output such that an amount of power transferred to the grid mains is dependent on an amplitude of a sinusoidal voltage component on the energy storage capacitor.

  • Publication number: 20190006723
    Abstract: Embodiments of the present invention include a battery management system that provide a plurality of channels that allow communication between host and clients. This communication may operate in bi-directional modes such that commands from the host and responses from the clients are transmitted clockwise or counter-clockwise around a daisy-chain loop. This architecture provides both a high level of redundancy across multiple channels as well as transmission directions around the loop. The use of multiple channels provides a separation in signal paths akin to the provision of completely separate physical wires, preventing malfunction of spurious operation of devices using one channel from interfering with the normal operation of devices using the other channel. In addition, the signaling architecture allows a host to dynamically transmit commands and receive responses between specific client(s) and host or broadcast communication across all clients.

  • Publication number: 20180314342
    Abstract: A vehicular interface system for providing application-based access to a plurality of vehicular subsystems is disclosed. The vehicular interface system includes a display for displaying a graphical user interface (GUI). A taskbar is displayed in a first portion of the GUI, the taskbar including a plurality of icons, each of icons representing a corresponding application. A plurality of windows is displayed in a second portion of the GUI. When determining that a user-selected icon is being dragged from an initial location on the taskbar, a semi-transparent overlay, corresponding to the application to be launched, is displayed on a window of the GUI as the selected icon is being dragged within the window. When determining that the selected icon is released within a selected window, the corresponding application is launched in the selected window. In general, the application provides control options or monitoring information relating to a subsystem of a vehicle.

  • Patent number: 10115838
    Abstract: One embodiment can provide a current-collecting mechanism of a photovoltaic structure. The current-collecting mechanism can include a top metallic grid positioned on a top surface of the photovoltaic structure and a bottom metallic grid positioned on the bottom surface of the photovoltaic structure. The top metallic grid can include a top busbar positioned near an edge of the photovoltaic structure, and the bottom metallic grid can include a bottom busbar positioned near an opposite edge. The top busbar and the bottom busbar can have complementary topology profiles such that, when the edge of the photovoltaic structure overlaps with an opposite edge of an adjacent photovoltaic structure, the top busbar of the photovoltaic structure and the bottom busbar of the adjacent photovoltaic structure interlock with each other.
