A few days ago, BMW released a color-changing car paint technology at CES 2022, which is officially called "electronic ink" technology, which can realize the one-button color change function of the body.
"E-ink" contains millions of transparent microcapsules with a diameter of only one hair thickness, and each microcapsule contains a negatively charged white pigment, as well as a positively charged black pigment, and when it is necessary to change color, the color change can be achieved with one click by controlling the electrodes on both sides of the microcapsule.
Of course, this technology is not just for discoloration, it can also reduce energy consumption. For example, when sunlight is strong, changing the body color to a light color can correspondingly reduce the impact of strong sunlight and high temperatures on the interior of the vehicle. On the contrary, when the sunlight is weak, the body becomes dark, which can absorb more heat, reduce the energy consumption of air conditioning, and effectively increase the mileage.
Although the technology of "electronic ink" is very cool, it will not be widely used, so for its paint repair problem, we do not have to worry about the sky, "electronic ink" technology is only AN EXPLORATION OF BMW in the field of sustainable development, and this exploration will be more and more in the future.
