This study deals with the human exposure to electromagnetic fields (EMFs) emitted by a dynamic wireless power transfer (D-WPT) system during charging operations of a compact electric vehicle (EV). Specifically, different postures of realistic anatomical models, i.e., standing or lying outside and driving inside the EV, are considered. The influence of the car chassis material is investigated as well. Compliance with EMF safety standards has proven that reference levels are exceeded in the extreme case of a bystander or lying person on the sidewalk at few centimetres from the car and of a driver when the chassis is modelled as carbon fiber. However, the system is always compliant with the basic restrictions, at least for the considered scenarios.

Abstract
This study deals with the human exposure to electromagnetic fields (EMFs) emitted by a dynamic wireless power transfer (D-WPT) system during charging operations of a compact electric vehicle (EV). Specifically, different postures of realistic anatomical models, i.e., standing or lying outside and driving inside the EV, are considered. The influence of the car chassis material is investigated as well. Compliance with EMF safety standards has proven that reference levels are exceeded in the extreme case of a bystander or lying person on the sidewalk at few centimetres from the car and of a driver when the chassis is modelled as carbon fiber. However, the system is always compliant with the basic restrictions, at least for the considered scenarios.Pubblicazioni consigliate
