Abstract

Embodiments of the present application provide an electrochromic device control method and an electrochromic device. The electrochromic device pre-stores gear representation parameter data, and the gear representation parameter data includes open circuit voltage and charge capacity data corresponding to the electrochromic device in different gears. The method includes: when a dimming instruction of a target gear is received, obtaining a current actual open circuit voltage of the electrochromic device; determining a charge capacity supplement value according to the actual open circuit voltage, a target open circuit voltage corresponding to the target gear, and the open circuit voltage and charge capacity data corresponding to different gears, so as to adjust the electrochromic device to switch to the target gear. The method can solve the problem that the gear switching process cannot be interrupted, and reduce the switching waiting time of the user.
