Abstract: Provided are a gear switching control method and apparatus for an electrochromic device and an electrochromic device. The method includes steps described below. During a process of switching from an initial gear before gear switching to an initial target gear, a gear characterization parameter state of the electrochromic device is acquired, and when a new gear switching signal carrying target gear information is received, a new target gear is acquired and a current charging operation or a current discharging operation is interrupted. A charging direction or a discharging direction after the interruption operation and a corresponding gear characterization parameter adjustment value are determined according to the gear characterization parameter state when the interruption operation is performed and a gear characterization parameter corresponding to the initial gear and a gear characterization parameter corresponding to the new target gear.

Abstract: The present disclosure provides an electrochromic sunroof encapsulating a pre-assembled all solid-state flexible thin film ECDs and methods to fabricate the disclosed electrochromic sunroof. The electrochromic sunroof of the present disclosure provides great flexibility and can be adapted to virtually any curvature or shape without leaking concerns.

Abstract: An electrochromic device, a preparation method therefor and an application thereof are disclosed. The electrochromic device comprises a first conductive layer, a color-changing layer and a second conductive layer that are arranged in succession, wherein at least one first electrode lead is connected on the first conductive layer, and the first electrode lead passes through the color-changing layer and the second conductive layer; and at least one second electrode lead is connected on the second conductive layer, and the second electrode lead passes through the color-changing layer and the first conductive layer. The electrochromic device can achieve the application of the electrochromic device under the premise that the two conductive layers are not staggered, and on the basis of implementing electrochromism, the technical effect of gradual color change can be achieved by means of changing the magnitude of the power supply voltage and/or current.
