Abstract: An electrochromic module and a driving method for an electrochromic are provided. The electrochromic module has an electrochromic device provided so as to be colored or bleached depending on an applied drive voltage, a sensing part for sensing an external temperature of the electrochromic device, a control part for determining an application time of a voltage satisfying a particular Relation Equation depending on the sensed external temperature, and a power supply part for applying a voltage to the electrochromic device by the determined application time.
