GEAR SHIFTING CONTROL METHOD AND APPARATUS FOR ELECTROCHROMIC DEVICE, AND ELECTROCHROMIC DEVICE

Provided are a gear switching control method and apparatus for an electrochromic device and an electrochromic device. The electrochromic device pre-stores gear characterization parameter data. 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 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, or according to the gear characterization parameter state when the interruption operation is performed and a gear characterization parameter corresponding to the new target gear. The electrochromic device is adjusted to switch to the new target gear according to the charging direction or the discharging direction and the corresponding gear characterization parameter adjustment value. The method can solve the problem that the gear switching process cannot be interrupted, so that the gear switching waiting time of the user is reduced.
