The electrochromic film can have the adjustability of light absorption and transmission under the action of an electric field, can effectively control external light transmission, and simultaneously changes the light transmission rate and the color.

Specifically, in the present embodiment, when the power is turned on, the COLOR _ SEL level is set as required, and the charging polarity of the electrochromic film is configured (the transmissive and non-transmissive states are set); then, starting the current type fuel gauge, enabling the PWR _ EN to enable the load switch, and charging the electrochromic film to realize the preset state of the electrochromic film; when the charge reaches charge capacity C (where the value of C characterizes different charge capacities rushing into the electrochromic film, with different values of C corresponding to different transmittances), PWR _ EN is configured low, the load switch is turned off, and the fuel gauge is turned off to stop charging the electrochromic film.

Optionally, in this embodiment, VPH _ PWR is a lithium battery voltage, and the voltage value is between 3.5V and 4.5V; PWR _ ON is a voltage signal of 1.8V or more; the COLOR _ SEL is a voltage signal of 3.3V or more. The PWR _ ON and COLOR _ SEL signals are both output control signals for the end processor or the assist processor.

The method has the advantages that a first voltage signal for starting charging is sent to the load switch through the processor, wherein the first voltage signal is a voltage signal of 1.8V or more; then, a second voltage signal is sent to the electrochromic film through the processor, and the charging charge of the electrochromic film is acquired in real time through the fuel gauge, wherein the second voltage signal is a voltage signal of 3.3V or more. The driving control scheme of the electrochromic film is more humanized, so that the light transmittance of the electrochromic film can be finely and continuously adjusted, and the implementation scheme is simple and reliable.
