ABSTRACT:
A process for electrical power supply of at least one electrically drivable glazing of the electrochromic type for the purpose of causing variation of the state of coloration thereof. An electrical drive circuit includes an electrical connection to connect electrically conductive layers of the glazing to the drive circuit. An electricity generator supplies power to the electrochromic glazing under instruction of a control unit equipped with a user interface, and which utilizes a counter for counting a time and which measures and computes physical characteristics of the drive circuit and of the glazing, including at least measuring the electrical voltage between two distinct points of the electrochromic structure of the glazing, and measuring the electric current and measuring the state of coloration of the glazing.
