ABSTRACT:
Electrochromic systems having a material, whose coloration state and/or the transmission in certain electromagnetic radiation wavelengths varies by performing an electrochemical reaction involving the passage of an electric current. The electric current is generated by an intensity generator able to supply a current, whose intensity obeys a reference value determined as a function of the number of charges to be transferred for switching from the initial coloration state to the desired coloration state and as a function of the time chosen for the switching. The system also relates to using a power supply in an electrochromic glazing process.
