  • Patent number: 10778139
    Abstract: Building integrated photovoltaic (BIPV) systems provide for solar panel arrays with improved aesthetics and efficiency that can replace a conventional roof surface structure. These BIPV systems can utilize photovoltaic PV roof tiles defined as glass tiles having photovoltaic elements embedded or incorporated into the body of the roof tile. Such PV roof tiles can include one or more lapping features for interfacing with adjacent tiles and features for electrically connecting multiples tiles within a course to an external power optimizer. Such PV roof tiles can utilize stamped glass that is stamped to define these features within an integrated glass tile and can further include texture, striations on the glass tile and/or color matched back layers or various other components to obscure visibility of any embedded solar cells and provide a more pleasing appearance.

  • Patent number: 10763477
    Abstract: A system and method for mitigating the effects of a thermal event within a non-metal-air battery pack is provided in which the hot gas and material generated during the event is directed into the metal-air cells of a metal-air battery pack. The metal-air cells provide a large thermal mass for absorbing at least a portion of the thermal energy generated during the event before it is released to the ambient environment. As a result, the risks to vehicle passengers, bystanders, first responders and property are limited.

  • Patent number: 10737304
    Abstract: A system for thermally servicing a solvent-refining column includes: a first solvent-refining column, a closed-loop water-steam system; a first heat-exchanger thermally coupling the closed-loop water-steam system to the top of the first solvent-refining column, a second heat-exchanger thermally coupling the closed-loop water-steam system to a bottom of the first solvent-refining column, and a compressor positioned between the first heat-exchanger and the second heat-exchanger. The first heat-exchanger boils pressurized water to steam by transferring first heat from the top of the first solvent-refining column to the closed-loop water- steam system. The compressor compresses the steam in the closed-loop water-steam system to a higher temperature. The second heat-exchanger provides second heat to the first solvent-refining column by condensing the steam at the bottom of the first solvent-refining column after compression by the compressor.

  • Patent number: 10741888
    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.

  • Patent number: 10734938
    Abstract: One embodiment provides a solar roof tile module. The module includes a plurality of solar roof tiles positioned side by side and one or more tile spacers. The tiles are electrically and mechanically coupled to each other. A tile spacer is positioned between two adjacent solar roof tiles, thereby preventing water leakage. A solar roof tile can include a front cover, a back cover, and a plurality of photovoltaic strips positioned between the front and back covers. Each photovoltaic strip includes a first edge busbar located on an edge of a first surface and a second edge busbar located on an opposite edge of a second surface, and the photovoltaic strips are arranged in such a way that the first edge busbar of a photovoltaic strip overlaps with a second edge busbar of an adjacent photovoltaic strip, thereby forming a serial connection among the photovoltaic strips.

  • Patent number: 10715175
    Abstract: Various embodiments of the invention provide systems, devices, and methods for decompressing encoded electronic data to increase decompression throughput using any number of decoding engines. In certain embodiments, this is accomplished by identifying and processing a next record in a pipeline operation before having to complete the decompression of a current record. Various embodiments take advantage of the knowledge of the method of how the records have been encoded, e.g., in a single long record, to greatly reduce delay time, compared with existing designs, when decompressing encoded electronic data.

  • Patent number: 10714735
    Abstract: A battery pack includes an enclosure containing a plurality of battery modules. A cooling system disposed among and electrically isolated from the plurality of battery modules uses a coolant solution that is a first mixture of a first liquid and a second liquid in a predetermined ratio to produce a first boiling point. Boiling of the coolant solution changes the predetermined ratio to produce a second boiling point that is higher than the first boiling point and that is sufficient to induce a thermal runaway condition for the plurality of battery module. A sensor monitors at least one operational characteristic of the plurality of battery modules and a controller determines a possible high voltage electrolysis within the enclosure based upon the at least one operational characteristic. A remediation system is responsive to the possible high voltage electrolysis to decrease risks associated with the possible high voltage electrolysis when operated.
