Study of the radiated emissions of an electric vehicle battery charger during the charge cycle

The development of hybrid/electric vehicles for land transport brings up new constraints in terms of electromagnetic compatibility and particularly low frequencies magnetic field radiations. This paper presents a study of an electric vehicle charger magnetic emissions during the different charge cycle phases. In fact, the electric vehicle battery charger under test is placed beneath the passenger seat; therefore its radiated emissions might affect not only the passengers but also the other electronic devices placed in its vicinity. This study gives designer clearer idea toward an optimized components´ arrangement inside the limited space of the vehicle to scale down the possible electromagnetic interference phenomena.
