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.
