    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) device includes a first substrate, a second substrate, a transparent first conductor disposed between the first and second substrates, a transparent second conductor disposed between the first and second substrates, a working electrode disposed between the first and second conductors, a counter electrode disposed between the working electrode and the second conductor, and an electrolyte disposed between the working and counter electrodes. At least one of the first or second conductors is a multipart conductor which includes a transparent first conductive film, a first contact strip extending lengthwise in a first direction which is perpendicular to a second direction, along a first side of the EC device, and first conductive lines extending from the first contact strip toward an opposing second side of the EC device. The multipart conductor has a lower effective sheet resistance in the second direction than in the first direction.
