  Replacing conventional vehicles by vehicles that operated with alternative energy sources is a significant step towards sustainable development of transport systems and efficient energy management. In our research, Hungarian characteristics and peculiarities are analysed; special focus is given to the applicability of renewable energy sources. The road electromobility system has been analysed according to energy production, vehicle stock, charging facility and operational aspects. We found that initial higher share of plug-in hybrid vehicles (PHEV) is gradually decreasing against that of pure battery electric vehicles (BEV). We investigated and compared electric vehicle cost calculators available online in English or Hungarian. We found that applications lack a drivetrain fitness evaluation method based on vehicle use. Accordingly, we have elaborated a conventional, hybrid and pure electric drivetrain type evaluation method, which is the main scientific contribution of the paper. The function was integrated into a new online cost calculator method in Hungarian, that may contribute to the spread of electric vehicles in Hungary.

  The 21st century has seen significant changes in supply chain management. Chains with an increased number of members are now considered more like networks in the literature. Cooperation between members, coordination and synchronisation of processes have become increasingly difficult. In addition, supply chains are increasingly expected to apply environmentally friendly systems, technologies and processes. The increasing levels of pollution and the decreasing levels of non-renewable resources are also indicative of the changes in business. The objectives of organisations, and therefore of supply chains and networks, include the use of environmentally friendly solutions, but this also complicates the operation of companies and thus has an impact on coordination between members. Therefore, we have focused on a coordination solution that can effectively support supply chain coordination based on literature. Contracts are potentially a good solution for member coordination, and therefore the focus of our study is on the potential of contracts as a means of coordination in a business sphere where environmental awareness is a high demand. Thus, our study aims to establish a group of experts who are decision makers in firms with high levels of environmental awareness. Based on their preferences and using the AHP method, we would like to develop a decision support model that would help to propose a contract that coordinates the partnership at the appropriate level, taking into account the characteristics, expectations and attitudes of environmentally aware companies.
