Energy analysis of charging infrastructure for electric vehicles on the TEN-T road network

Electromobility is a European vision of future motorization. In Poland, there are plans to introduce a million vehicles of this type by 2030. Currently, their share is marginal (about 1 percent). This vision is to be made real. This is due to the fact that vehicle manufacturers are developing newer EV vehicle constructions. Increasing the number of electric vehicles requires the development of their charging infrastructure. Based on the work of the authors regarding the EV vehicle charging network on the Trans-European Transport Network road network, it was possible to extend this issue with energy calculations related to energy demand for supplying the EV vehicle charging network. This is an important topic from the point of view of the State's energy needs. The calculations made in the article present the problem of the need to increase the production of electricity, which in the case of Poland is associated with increased emissions of harmful substances and the possibility of periodic interruptions in the supply of electricity. Due to excessive domestic consumption with too little production. The second issue is the need to supply electricity to the charging station (infrastructure), as well as transmission losses, which limit the possibility of building multi-station fast charging stations. The issue presented by the authors in this article is one of the key problems relating to the introduction of electromobility in Poland. The key is to determine how large the demand for electricity in the country will be if a greater number of electric vehicles is put into operation. Considering that there are power shortages during a hot summer, this may affect the possibility of using electric vehicles in the country.
