The invention relates to the field of electrochromic, in particular to a glass capable of changing color.
At present, more and more automatic color-changing anti-glare rearview mirrors are used on vehicles, and mainly EC glass, namely electrochromic glass is adopted, optical signals are converted into electric signals through photosensitive elements, and MCU (micro control Unit) calculates and outputs the voltages to an executing device (electrochromic glass). In the prior art, the glass voltage of a device used in the field of rearview mirrors is about 1.2V, and in the actual use process, a vehicle-mounted 12V voltage is generally used for providing power, 12V is converted into 5V (for providing working voltage for a chip) through a step-down link or a power chip, and then is converted into 1.2V (for providing the executive device, namely electrochromic glass) from 5V. The invention mainly provides electrochromic glass, the driving voltage of which is 12V, and the electrochromic glass can be directly powered by a vehicle, so that a step-down link is omitted, and the cost is greatly reduced.

| project | Minimum of | Standard of | Maximum value | Unit (B) |
| Supply voltage | 0.8 | 1.25 | 3.5 | V |
| Supplying current | 40 | 180 | 400 | mA |
