Patent abstract
A method of determining the transmission state of an electrochromic device includes applying a voltage across the electrochromic device, using the applied voltage and current for calculating leakage current of the electrochromic device and determining ionic current as the difference between the applied current and the leakage current. The method includes using the ionic current for determining the transmission state of the electrochromic device.
