First, please refer to the first diagram of the characteristics of the input voltage of the electrochromic element. When the external power source is input to the electrochromic element, the transmittance of the electrochromic element is reduced, the absorbance is increased, the color is deeper, and the oxidation reaction is performed. When the electrochromic element is limited by the same transmittance condition, if different voltages are input, different current values and different changing speeds are generated, so that the current value of the same transmittance can be achieved by different input voltages. The relationship between the speeds of change shows that regardless of the input voltage, the sum of the current values per second will form the same total current flux value (please refer to the second figure for the total input of 2.5V of the electrochromic element). Schematic diagram of current area, schematic diagram of total current area when inputting 2.0V of electrochromic element in the third figure, and schematic diagram of total current area when inputting 1.5V of electrochromic element in the fourth figure], for example, the current value is 50mA+ in the first second.

Please refer to the fifth diagram for the aging phenomenon of electrochromic components, and because the electrochromic components will age after using them for a period of time, that is, input the same voltage, the same amount of current and the same light. In the case of degree, the speed of change of transmittance will change. For example, the speed of change of transmittance between the first, the 4,000th and the 6,000th will become faster and faster, resulting in the first time. The transmittance change speed time is calculated, and the transmittance is not the required transmittance.
