no. 1 approach

[0027] A first embodiment of the present invention will be described with reference to the drawings. figure 1 It is an external view of the power supply system 1 according to this embodiment. exist figure 1 In the shown example, the power supply system 1 is configured to include a power transmission unit 10 provided on the power transmission side, and a power reception unit 20 provided on the power reception side.

[0028] The power transmission unit 10 is configured as a power transmission device including a power transmission coil 11 that transmits acquired power. The supplied AC power flows through the power transmission coil 11 . Since the intensity of the current varies with time, the intensity of the magnetic field around the power transmission coil 11 varies. This variation is radiated from the power transmission coil 11 as an electromagnetic wave.

[0029] The power receiving unit 20 receives power transmitted by electromagnetic waves when located in the charging a...

no. 2 approach

[0080] Next, a second embodiment of the present invention will be described. About the same structure as embodiment mentioned above, the same code|symbol is attached|subjected, and the description is referred. Figure 6 It is a schematic block diagram of the power supply system 1A according to this embodiment. The power supply system 1A is configured to include a power transmission unit 10 and a power reception unit 20A.

[0081] The power receiving section 20A is in the power receiving section 20 ( figure 2 ) includes a charging control unit 24A instead of the charging control unit 24, and further includes a priority input unit 28A. The priority of the machine itself is input to the priority input unit 28A, and priority information indicating the input priority is stored in the priority storage unit 27 . At this time, the priority information stored in the priority storage unit 27 is updated. The priority input unit 28A may be configured to include an operation device th...

no. 3 approach

[0098] Next, a third embodiment of the present invention will be described. About the same structure as the above-mentioned embodiment, the same code|symbol is attached|subjected, and the description is referred. Figure 9 It is a schematic block diagram of the power supply system 1B according to this embodiment. The power supply system 1B is configured to include a power transmission unit 10B and a power reception unit 20 .

[0099] The power transmission unit 10B is in the power transmission unit 10 ( figure 2 ) includes a power transmission control unit 12B instead of the power transmission control unit 12, and further includes a priority input unit 15B. In the priority input unit 15B, the priority of an arbitrary power receiving unit 20 is input, and priority information indicating the input priority is stored in the priority table 14 in association with the device ID of the power receiving unit 20 . . At this time, among the priority information already stored in the...

Abstract

According to the present invention, a power transmission unit transmits power, and a power control unit detects one or a plurality of power reception units for receiving power, and controls the powertransmission unit so that a greater amount of power is transmitted to a power receiving unit having a higher priority. According to one embodiment of the present invention, a power transmission device, and a power supply system provided with a power reception device and a power transmission device, can be realized. The power supply system can also be realized as further being provided with an electronic device for consuming the power received by the power reception device.

Description

technical field [0001] The invention relates to a power transmitting device, a power supply system and a power receiving device. [0002] This application claims priority based on Japanese Patent Application No. 2016-025994 for which it applied in Japan on February 15, 2016, and uses the content here. Background technique [0003] Devices such as mobile phones that users use while moving usually consume the power stored in the battery, so charging is essential to ensure sufficient power for operation. On the other hand, the charging operation may be troublesome for the user. Therefore, a non-contact power supply system that charges various devices in a non-contact (wireless) manner has attracted attention. The non-contact power supply system may also be called a non-contact charging system or a non-contact power transmission system. The contactless power supply system adopts a power supply method such as a magnetic field resonance method, includes a power transmission uni...
