●BMW iX Flow unveiled for the first time at CES 2022
●Freely change the body color?Realize fictional technology
● Introduced electronic paper technology
●Advantages other than design
● Risk of vehicle theft and damage
On January 5, 2021, local time in the United States, BMW released the concept car "BMW iX Flow" that can change the appearance color for the first time in the world. In addition to this concept car, the new car "iX M60" was announced at the same time, and the BMW iX Flow was only released as a concept car, and there is no plan to sell it on the market.
The biggest feature of BMW iX Flow is that it can freely change the appearance color. If it is grayscale, you can also freely adjust the depth of the color. The next second you think it is a black car, it may become a white car. The fictional technology in the movie Green Hornet and the Avengers series has been moved to the real world.
You can also change the local color!
You can achieve your favorite design style by changing the color of the partial appearance, and the matching style is changeable, but if this technology is really carried on a general vehicle, it will be difficult to find it back if the design is changed after the vehicle is stolen.
This technology that can freely change the color of the car body actually comes from the "electronic ink technology (E-ink)" used by e-book readers. The appearance of BMW iX Flow adopts a special coating of e-ink technology, which contains digital ink. Millions of microcapsules with a diameter of about the size of human hair, and this microcapsule contains negatively charged white pigment and positively charged black pigment. After the electric field is stimulated, the pigment will concentrate on the surface of the microcapsule, forming a visible form to the naked eye. s color.
Simply put, it is to stick several pieces of electronic paper on the car body, but if you want to highlight the unique contour of the car body or reflect the changes of light and shadow, the position of the sticker needs to be carefully planned. BMW uses an algorithm to achieve these goals. "Generative Design" with laser cutting technology, and then configure the electronic paper according to the contour of the car body.
The advantage of changing the color of the exterior is not only to improve the design, for example, in different seasons, the color of the body will also affect the absorption of heat energy. If it is black, it will increase the absorption of heat energy and cause the temperature to rise. lower.
If it can reduce the use of energy, it means that it will help to reduce the use of fuel and electricity. For example, the electric vehicle iX may have a longer cruising range, and the electronic ink technology itself does not consume energy. Powered up when changing colors, the BMW iX Flow is, in conclusion, an environmentally friendly presence.
As mentioned earlier, the fact that the color of the car can be changed is very unfavorable for recovery when it is stolen. In addition, because the surface of the BMW iX Flow has undergone a special coating, if it is accidentally damaged, it will not only lose the color-changing feature, but also may have to pay for it. It costs quite a lot to repair, but it seems that a concept car should not consider so many practical problems, and we can only wait and see how this technology will be applied.
