A control method for the an electrochromic device includes: determining whether a current transmittance of the electrochromic device reaches a preset transmittance; when determining that the current transmittance does not reach the preset transmittance, controlling an external power supply to perform a first mode charging and discharging on the electrochromic device until the current transmittance reaches the preset transmittance; when determining that the current transmittance reaches the preset transmittance, suspending the charging and discharging, and continuously monitoring whether a current open circuit potential of the electrochromic device is within a preset open circuit potential threshold range; and if the current open circuit potential is not within the preset open circuit potential threshold range, controlling the external power supply to perform a second mode charging and discharging on the electrochromic device to enable the current open circuit potential to be continuously within the preset open circuit potential threshold range.
