  • Patent number: 11467463
    Abstract: A overcharge-aware electrochromic device driver for preventing overcharge of an electrochromic device is described. One driver applies a constant supply current to an electrochromic device from a power supply. The driver determines an amount of charge as a function of time and current supplied to the electrochromic device. The driver determines whether the amount of charge reaches an overcharge limit before a sense voltage reaches a first sense voltage limit. Responsive to the amount of charge reaching the overcharge limit, the driver sets the sense voltage as a second sense voltage limit that is lower than the first sense voltage limit, ceases the constant supply current, and applies one of a variable voltage or a variable current to the electrochromic device from the power supply to maintain the sense voltage at the second sense voltage limit.

  • Patent number: 10705403
    Abstract: A method of controlling an electrochromic device is provided. The method includes measuring an open circuit voltage between a first electrode and a reference electrode in the electrochromic device in a fully bleached state. The method includes calculating a charge Q to return the first electrode to a baseline state and darkening the first electrode in the electrochromic device to a darkened state. The method includes transferring charge from the first electrode in the darkened state to a redox element.
