Abstract: Various embodiments disclosed herein relate to techniques for simultaneously designing optical and electrical properties of an electrochromic device by tuning specific parameters of the electrochromic device. One or more models representing respective relationships of the optical and electrical properties with respect to the individual ones of the parameters of the device may be obtained. Given specific values of the optical and/or electrical properties, at least one of the parameters may be adjusted to simultaneously control the optical and electrical properties according to the given specific values.

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: 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: 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.

Abstract: A method can be used to control the operation of one or more non-light-emitting, variable transmission devices. In an embodiment, a method of operating a plurality of non-light-emitting, variable transmission devices can include receiving requests for requested visible transmittance for the non-light-emitting, variable transmission devices; determining operating parameters for the non-light-emitting, variable transmission devices; and operating the non-light-emitting, variable transmission devices at the operating parameters, wherein the operating parameters for the non-light-emitting, variable transmission devices are different. In another aspect, the method can include operating the non-light-emitting, variable transmission device at a first operating parameter for a time period, wherein the operating parameter corresponds to an intermediate visible transmittance; generating a characterization parameter based at least part on the voltage and current measurements that are obtained during the time period; and controlling the non-light-emitting, variable transmission device period based at least in part on the characterization parameter.
