Electrochromic system and method for its power supply.

摘要

The electrochromic system comprises a material whose state of transmission in certain electromagnetic wavelengths varies with an electrochemical reaction involving the passage of an electric current. The electric current is generated by intensity generator (8) capable of delivering a current whose intensity corresponds to a set value determined as a function of the number of charges to be transferred to change from the initial state to the desired state and as a function of the length of time selected for the change. The intensity of current supplied by the generator (8) is determined independently of the operating temperature of the system (1). The current intensity supplied is regulated to stay at low values. <IMAGE>
