A capacitive wireless charging system for use with a vehicle includes a roadway-side capacitive charging pad configured to be embedded in a roadway and to form a capacitive electrical connection with a vehicle-side capacitive charging pad for wirelessly transferring power to charge a vehicle battery when the vehicle is on the roadway, a power conditioning circuit configured to be positioned next to the roadway and to condition power received from a power source, and a plurality of conductors configured to be at least partially embedded in the roadway and to electrically connect the power conditioning circuit and the roadway-side capacitive charging pad, such that the plurality of conductors form a roadway-side matching network for the capacitive electrical connection without discrete inductors and capacitors.
