Managing the maintenance activity of electric vehicle charging station networks to guarantee the health and safety of workers

The achievement of European and national targets and objectives regarding the installation of alternative fuel infrastructure to utilise zero-emission propulsion technologies in the road sector through the application of economic incentives has led to the development of electric and hybrid vehicle fleets and the establishment of electric vehicle recharging infrastructure. The paper presents the results of research studies on diagnosing technological and occupational risks generated by the maintenance activities of the electricity supply infrastructure for road transport. The validation and evaluation of the models of electric charging stations in use highlighted for maintenance personnel a series of significant electrical risks, including those generated by electrical short circuits and mechanical failures, as well as the risk of fire associated with the heating of the electric vehicle's battery during charging. In order to manage technological risks and occupational risks generated in the maintenance activity of electric vehicle charging station networks, the general decision support system (DSS) was developed so that by identifying the risks of occupational accidents and illnesses, implementing security measures, planning and organising preventive maintenance and corrective maintenance activities, the risks for workers and users are minimised.
