As part of the Master Thesis, the main topic was the company Rimac Automobili. Currently, the most popular Croatian company has experienced great growth in the last ten years. From a garage, they became the company with the fastest-accelerating car in the world, which goes into series production. Rimac Automobili d.o.o. becomes part of the Rimac Group and includes two companies: Bugatti Rimac (created by merging the world-famous car brand Bugatti) and Rimac Technology (production and development of batteries, various electrical systems and concepts for automotive manufacturers). The construction of a mega project called Campus is underway. Details about this company are discussed below. As a company within the Rimac Group, Rimac Technology is developing high technology in which the biggest focus is on production of battery packs for the world market. Considering the future of the automotive industry, the technological process of making a battery packs has been taken as a main topic of this thesis. In addition to the description of the product itself, the component of each subassembly that builds the battery is analyzed in details, and the technological process of making each of these subassemblies is divided by workstations. Also, a conceptual solution was proposed for a new concept of making battery packs by introducing technologies related to Industry 4.0. Finally, a simulation of a new production process was made with a focus on transport routes and the logistics supply of the production line with the components needed to assemble the battery pack.
