Temperature control for electrochromic devices

A method of controlling a temperature of an electrochromic device, comprising:

• determining a current temperature of the electrochromic device, wherein the electrochromic device comprises a first transparent conductor electrically connected to a working electrode, and a second transparent conductor electrically connected to a counter electrode;
• applying the heating current to the first transparent conductor and the second transparent conductor, when the current temperature is determined to be below a minimum temperature, wherein the heating current heats the electrochromic device via the first transparent conductor and the second transparent conductor;
• and
• applying a working current between the working electrode and the counter electrode to change a transmission state of the working electrode.
