Abstract: Various embodiments may include methods of controlling a temperature of an electrochromic device. The methods may include determining a current temperature of the electrochromic device which includes a first transparent conductor electrically connected to a working electrode, and a second transparent conductor electrically connected to a counter electrode, and applying the heating current to the first transparent conductor and the second transparent conductor if the current temperature is below a minimum temperature to heat the electrochromic device. Further embodiments may include an electrochromic system including an electrochromic device and a controller configured to control the temperature of the electrochromic device.

Abstract: An electrochromic (EC) privacy window includes an EC pane unit including a first EC device having a bright state and a dark state, and a privacy device facing the EC pane unit and having a bright state and a privacy state configured to attenuate visible radiation transmitted through the window. In some embodiments, when the privacy device is in the privacy state, the window has transmitted haze of greater that 80%. In other embodiments, when the privacy device is in the privacy state and the first EC device is in the dark state, the window has a visible transmittance of about 0.1% or less.
