Abstract:
PROBLEM TO BE SOLVED: To provide a control system for an electrochromic (EC) device which can monitor the temperature of the EC device without requiring an external temperature monitoring element and control the EC device based on the temperature readings. SOLUTION: The control system provides methods for heating the EC device using current flowing through the device and for simultaneously heating and changing the transmissivity level of the device. The controller also provides security feedback by detecting glass breakage via a high frequency impedance measurement of the EC device. The controller also provides for methods of determining the bleaching/coloring history of the EC device, determining the transition state of the EC device, and applying a holding voltage to maintain the transmission state of the EC device.

Abstract:
An electrochromic device is structured to selectively heat one or more particular regions of a conductive layer of the electrochromic device. An electrical potential difference can be induced across the conductive layer to heat one or more layer regions. The conductive layer can be one of at least two conductive layers on opposite sides of an electrochromic film stack, and an electrical potential difference can be induced between the conductive layers to cause at least some of the electrochromic film stack to change transmission levels. The conductive layer can include regions with different sheet resistances, so that one or more regions are structured to generate more heat than other regions of the conductive layer when an electrical potential difference is induced across the conductive layer. Separate layer regions can include separate chemical species. The conductive layer can be geometrically structured so that some layer regions have a greater sheet resistance than other regions.
