Ynvisible Interactive Inc. announced a collaboration with Exevio. Exevio has engaged Ynvisible on a project in Croatia to produce a digital e-paper road sign that informs the availability of EV charging stations. The project was supported by the Centre of Competence for Smart Cities (CEKOM), a government-backed organization that encourages R&D in the field of smart cities which includes electric vehicles.

With the electric vehicle market growing at a staggering rate, a growing issue is the lack of EV chargers on the road causing charging stations to be congested. The problem is that when an individual arrives at an EV charging station to charge their car, they find the chargers occupied. Before Ynvisible and Exevio's digital signage solution, the only way to know if a stall was available was to use a mobile app while driving, endangering yourself and others.

With the implementation of the digital signs on critical locations such as significant intersections, parking entrances or above the EV stations themselves, drivers can now be informed of the availability of the charging stations, thereby lowering the need to use a smartphone while driving. The digital road sign needed to be extremely low power, energy independent and send out geo-location data in order to be sustainable and autonomous on the open road. It also needed to satisfy road safety law and emit minimum visual stimuli to prevent distraction when driving, whilst also looking like a traditional traffic sign.
