摘要： A wireless power transmission apparatus comprises: a plurality of transmission coils configured to transmit a wireless power to a wireless power reception apparatus; a shielding coil which is arranged on at least one surface of a dielectric substrate, and is configured in a loop shape having at least two turns so as to surround the plurality of transmission coils; and a capacitor configured to connect one point to the other point of the shielding coil. The plurality of transmission coils are arranged inside the shielding coil disposed on the dielectric substrate, and the direction of a magnetic field formed at one side and the other side of the plurality of transmission coils adjacent to the shielding coil is formed to be opposite to the direction of a magnetic field formed around the shielding coil so that the shielding coil shields external exposure of electromagnetic waves by the plurality of transmission coils.

摘要： An IPT system magnetic flux pad includes two substantially planar coils (17) in close proximity to each other above a magnetically permeable core (14). The coils (17) each define a pole area (11, 12) and the distance between one or more adjacent turns of the coils (17) located in a region between the pole areas (11, 12) being different from the distance between one or more adjacent turns of the coils (17) located outside the region between the pole areas (11, 12).

摘要： A footwear system includes a sensorized insole, a wireless charging transmitter pod, and a wireless charging mat. The insole has an insole bulk having a foot-facing upper surface and a ground-facing lower surface. One or more sensors, one or more batteries, and a wireless charging receiver pod are embedded in the insole bulk. The transmitter pod receives energy and wirelessly transmits energy to the receiver pod. The transmitter pod is positionable against the foot-facing upper surface to wirelessly provide energy to the receiver pod through the insole bulk. The mat receives energy and wirelessly transmits energy to the receiver pod. The mat is positionable adjacent the ground-facing lower surface to wirelessly provide energy to the receiver pod through the first insole bulk. The system is configured to allow only one of the transmitter pod and the mat to provide energy to the receiver pod at a given time.

摘要： A battery charging apparatus for device charging in a vehicle includes a charging device compartment, a housing, a blower, a charger, and a duct. The charging device compartment is configured to retain at least one device. The housing includes a top member, a bottom member, and an accommodating space. The housing further includes an air-return port. The blower is in the housing and has an input port and an output port. The charger is in the housing and between the top member of the housing and the blower. The duct has an input port and an output port. The input port of the duct is coupled to the output port of the blower, and the output port of the duct is coupled to the air-return port of the housing. The duct forms a barrier between the accommodating space and the air-return port of the housing.

摘要： A wireless charging system having a power transmitter may wirelessly transfer power to a power receiver. Shield saturation, such as saturation of a ferrite structure, in the wireless power receiver may occur under some operating conditions. Saturation can lead to disruptive oscillations in power transfer. The power transmitting may include control circuitry for detecting and mitigating saturation.
