    Abstract: Dynamic systems may require a large number of coils (charging pads) which may be installed into the roadway to wirelessly provide power to electric vehicles as they are traveling along the roadway. The current in each of these coils may need to be turned on and off as a vehicle drives over the coils in order to efficiently utilize power and properly convey power to the passing vehicles. The supply network behind these coils may need to be capable of managing the individual coils with minimal infrastructure and cost as well as be capable of distributing the required power from the power grid to these pads efficiently and safely. The supply network may include charging coils, switches, local controllers, and distribution circuitry within a modular element, which may receive power from external sources and may be controlled by a central controller.

The apparatus comprises a receiver communication circuit (639), coupled to a receive coil (618) and to a load (636). The receiver communication circuit is configured to receive information associated with at least one characteristic of the charging transmitter. The apparatus further comprises a sensor circuit (635) configured to measure a value of a short circuit current or an open circuit voltage associated with the receive coil. The apparatus further comprises a controller (638) configured to compare the value of the short circuit current or the open circuit voltage to a threshold charging parameter set at a level that provides charging power sufficient to charge the load. The controller may be further configured to initiate receiving the charging power from the charging transmitter when the short circuit current or the open circuit voltage associated with the receive coil is greater than or equal to the threshold charging parameter.

    Abstract: Systems and methods are described that reduce magnetic flux density proximate to a wireless charging pad, such as a WEVC pad. These systems and methods control peak magnetic flux density in air around a WEVC pad to reduce potentially dangerous heat produced in foreign metal objects affected by a magnetic field generated by a coil of the WEVC pad. Controlling the peak magnetic flux density results in a safer WEVC pad. Aspects include ferrite tiles being separated by gaps having predefined sizes to increase a magnetic reluctance of a path of the magnetic flux through the ferrite tiles, which reduces a peak magnetic flux density experienced in areas proximate to the coil. In addition, the ferrite tiles can be arranged such that a combination of gaps are aligned with a region overlapping the coil.
