  • Publication number: 20220404676
    Abstract: When transitioning an electrochromic (EC) device between two tint levels, a control unit may repeatedly adjust an applied voltage based on a stack voltage of the EC device. The stack voltage of the EC device may be measured and compared to a reference or target stack voltage. The stack voltage may be measured in any of various methods, such as by measuring it directly, via a measured equivalent series resistance, or via an open circuit voltage measurement. The applied voltage may then be changed or adjusted based on the measured stack voltage and the comparison of the stack voltage to the reference value. This process may be repeated multiple times and may essentially be performed continually until the stack voltage attains the desired level or at least attains a level within a predetermine threshold of the desired level.
