The IAA Hannover 2018 fair, which ended just a couple of days ago and where we were participants, proved that the e-mobility trend is permanent, and the solutions which until recently were prototype have now entered mass production. The fair included 2,174 exhibitors from 48 countries. They all premiered 400 solutions, most of which in the field of e-mobility. The exhibitors also showed several dozen models of buses, vans, and trucks with electric drive. Most of these vehicles are intended for use in urban traffic. At our stand, we showcased the battery systems dedicated to buses, rail vehicles, and commercial vehicles.
