1. A system for charging an electric vehicle, the system comprising:
- a charging system including a power source and a charging plate wirelessly coupled to the power source, wherein the power source wirelessly transfers power to the charging plate;
at least one shield portion between the charging plate and a passenger compartment of the electric vehicle, wherein the at least one shield portion is configured to attenuate an electromagnetic field provided by the charging system; and
an active cancellation management unit configured to generate an electromagnetic field which at least partially opposes the electromagnetic field provided by the charging system and received within the passenger compartment.
