Abstract
An electrochromic device is disclosed. The electrochromic device includes a pair of bases, and both a primary and a reference electrochromic element provided between the bases. The reference electrode is electrically connected to the primary electrochromic element so as to maintain the color-developing and fading potentials of the primary electrochromic element at predetermined voltages. A power regulator is also provided for driving the primary electrochromic element based in part on the output of the reference electrochromic element.
