Abstract: A system for reusing power from a smart glass is provided. The system includes a power storage device. The system also includes a synchronous converter configured to change a voltage of electrical power. The system further includes a smart glass in electrical communication with the power storage device, the synchronous converter, and a controller. The smart glass is configured to change or maintain a tint in response to a voltage. In addition, the system includes the controller. The controller is configured to receive an indication that the smart glass is to change a tint. The smart glass has a non-zero voltage between two electrical connections. The controller is configured to change, using the synchronous converter, the voltage from the smart glass to a different voltage. The controller is configured to apply the changed voltage to the power storage device to transfer electrical energy for storage and smart glass tinting.

Abstract: An apparatus can include an electrochromic device configured to be maintained a continuously graded transmission state. When using the apparatus, the electrochromic device can be switched from a first transmission state to a continuously graded transmission state and maintained in the continuously graded transmission state. The current during switching can be higher than current during maintaining the continuously graded transmission state. In an embodiment, the grading can be reversed to provide a mirror image of the grading. In another embodiment, at least 27% and up to 100% of the electrochromic device can be in a continuously graded transmission state. The control device can be located within an insulating glass unit, adjacent to the insulating glass unit, or remotely from the insulating glass unit. In a further embodiment, a gap between bus bars can be used to form a portion of the electrochromic device that can be continuously graded.

Abstract: An apparatus can include an electrochromic device. When using the apparatus, the electrochromic device can be switched from a first transmission state to a continuously graded state and maintained at continuously graded transmission state. An apparatus can include an active stack with a first transparent conductive layer, a second transparent conductive layer, an anodic electrochemical layer between the first and the second transparent conductive layers, and a cathodic electrochemical layer between the first and the second transparent conductive layers. The apparatus can further include a first bus bar electrically coupled to the first transparent conductive layer, a second bus bar electrically coupled to the second transparent conductive layer, where the second bus bar is generally non-parallel to the first bus bar, and a third bus bar electrically coupled to the first transparent conductive layer, where the third bus bar is generally parallel to the first bus bar.

Abstract: Various embodiments of systems and methods for long-term benchmarking of electrochromic glass unit (“EGU”) are described. In some embodiments, a device monitoring and control system can transmit control messages to respective communication gateways for a plurality of remote installation sites for EGUs to benchmark the state the EGUs. During a low usage time of the EGUs, an installation site control system can collect telemetry data while cycling the state of its EGUs between clear and full tint to perform the benchmarking. The device monitoring and control system can receive messages from the installation sites, where the messages comprise the telemetry data associated with the benchmarking of the EGUs. The device monitoring and control system can store the telemetry data in data storage, perform analytics functions on the telemetry data at a data analytics engine, and provide results of the analytics functions to one or more remote destinations.

Abstract: An electrochromic device is disclosed. The electrochromic device can include a stack of layers. The stack of layers can include a first transparent conductive layer on a substrate, a second transparent conductive layer, a cathodic electrochromic layer between the first transparent conductive layer and the second transparent conductive layer, and an anodic electrochromic layer between the first transparent conductive layer and the second transparent conductive layer. The stack of layers can be patterned. In one embodiment, the pattern can be parallel to a voltage gradient of the electrochromic device. In another embodiment, the pattern can extend through all layers of the stack of layers of the electrochromic device.

Abstract: When transitioning an electrochromic (EC) device between two tint levels, a control unit may repeatedly adjust an applied voltage based on a stack voltage of the EC device. The stack voltage of the EC device may be measured and compared to a reference or target stack voltage. The stack voltage may be measured in any of various methods, such as by measuring it directly, via a measured equivalent series resistance, or via an open circuit voltage measurement. The applied voltage may then be changed or adjusted based on the measured stack voltage and the comparison of the stack voltage to the reference value. This process may be repeated multiple times and may essentially be performed continually until the stack voltage attains the desired level or at least attains a level within a predetermine threshold of the desired level.
