The German automaker, BMW debuted its new color-changing paint technology, E-Ink at the 2022 Consumer Electronics Show (CES) hosted in Las Vegas. At CES 2022, the company unveiled an e-ink vehicle exterior that can change colors depending on weather and traffic conditions or just the driver’s mood.
BMW to Integrate the Color-Changing Paint Technology to its Latest Automobiles
Furthermore, the electrophoretic coloring material itself is applied as a vehicle body wrap but functions just like its e-ink displays do in Kindle. The wrap is implanted with millions of microcapsules each containing a negatively-charged white pigment and a positively charged-black pigment employing the color-changing paint technology.
Depending on the environment, applying an electrical charge to the color-changing paint technology will push either the white or black pigments to rise to the top of the microcapsule, changing the vehicle’s color in moments. While the current iteration can only swap between a pair of colors, the palette could ultimately be developed to display a rainbow’s worth of differing hues.
“This gives the driver the freedom to express different facets of their personality or even their enjoyment of change outwardly and to redefine this each time they sit into their car,” Stella Clarke, Head of Project for the BMW iX Flow featuring E Ink, said in a prepared statement. “Similar to fashion or the status ads on social media channels, the vehicle then becomes an expression of different moods and circumstances in daily life.”
Currently E-Ink Has Limited Color Options
The innovative color-changing paint technology scheme can be activated at the touch of a button. Right now, the colors are limited to white, black, and grey. But despite the constrained palette, BMW says it could have implications for the efficiency of its electric vehicles.
The new color-changing paint technology, E-ink exterior displays could also establish to be useful in more functional applications such as changing colors depending on the weather to improve a vehicle’s battery life in cold climates or decrease the need for air conditioning in balmy weather.
