- the control unit 10 detects whether or not the mobile terminal 23 is placed on the upper surface (mobile terminal installation unit) of the support plate 6 and also the mobile terminal 23. Is detected (more precisely, the position of the receiving coil inside the portable terminal). Specifically, the self-excited oscillation circuit 15 is turned on, and pulse waves are output to the plurality of detection coils 12 (S1). At this time, the impedance measurement circuit 17 measures the impedance of each of the plurality of detection coils 12 in order (S2). Then, it is monitored which of the plurality of detection coils 12 has the impedance change (S3).
- the output voltage of the magnetic field transmitted from the detection coil is extremely small compared to the magnetic field output in the ping operation described later, and therefore, the influence on other in-vehicle devices using electromagnetic waves is small.

- the threshold is set to a resonance frequency or resonance voltage value at a normal level when the portable terminal 23 is not placed. It can be seen that the impedance has changed due to the change in the resonance frequency and / or the resonance voltage in any one of the plurality of detection coils 12. More specifically, a change in resonance voltage reflects a resistance component (R component) of impedance change, and a resonance frequency reflects a reactance component (L component) of impedance change. When a metal object is placed on the upper surface of the support plate 6, the resonance frequency increases and the resonance voltage decreases.
- the process proceeds to S4. If no change in impedance is detected, the process returns to S2 again, and the impedance measurement of the detection coil 12 is performed again.

Specifically, a charging coil corresponding to a detection coil that has detected an impedance change is selected from the plurality of charging coils 11 (S4), and a magnetic field is output from the selected charging coil (S6). Note that the self-excited oscillation circuit 15 is temporarily turned off before the magnetic field output from the charging coil (S5).

- a predetermined response signal is obtained in S7, it is determined that communication with the portable terminal 23 has been established, and a full-scale charging operation is started (S8).
- S7 when a predetermined response signal is not obtained, it is determined that communication is not established, and the process returns to S1 again.
- an operation for outputting a magnetic field for a short time until the presence / absence of a response from the portable terminal 23 is determined is referred to as a ping operation.
- the mobile terminal 23 returns a predetermined response signal to the mobile terminal charging device 5 in response to receiving the magnetic field output from the charging coil of the mobile terminal charging device 5. At this time, the portable terminal 23 varies the value of the load connected to the power receiving coil.
- the response signal is received by detecting the reflected impedance of the load fluctuation by the signal receiving circuit connected to the charging coil of the mobile terminal charging device 5. Such a signal transmission / reception method is called load modulation.
- the response signal returned from the portable terminal 23 may be a simple signal that only indicates that communication has been established, or may include ID information that indicates the type or the like of the portable terminal 23.
- the control unit 10 monitors whether the communication with the portable terminal 23 is continuously established, and continues the charging if the communication is continued. If the communication is interrupted, the process returns to S1 to confirm again the presence or absence of the mobile terminal. Further, during the charging operation (S8), the control unit 10 monitors whether or not a signal indicating that the charging is completed is transmitted from the portable terminal 23. If the charging is not completed, the control unit 10 continues the charging. If is completed, charging is stopped (S9).

Therefore, each of the detection coils L1, L3, L5, L7, and L9 is disposed almost directly above the corresponding charging coil.
- the center in the arrangement direction of each detection coil overlaps the end in the arrangement direction of the charging coils. Therefore, the detection coils L2, L4, L6, and L8 are disposed across two adjacent charging coils.
- the width of each detection coil is one half or more of the width of each charging coil. If the width of the detection coil is smaller than half the width of the charging coil, a gap is formed between the detection coils. Moreover, it is preferable that the length of each detection coil is substantially the same as the length of each charging coil. With this configuration, almost the entire area of the charging coil can be covered with the detection coil without excess or deficiency.

That is, the detection coils L2, L4, L5, and L7 are disposed across two adjacent charging coils. These four detection coils serve as a second set of detection coils. There is no detection coil located directly above the charging coil Lc3.
- the operation of the second embodiment is as follows. First, when the maximum impedance change is detected in any of the first set of detection coils (L1, L3, L6, L8), the charging coil immediately below the detection coil in which the maximum impedance change is detected is , Selected as the corresponding charging coil.
- the control unit 10 determines that the power reception coil 24 of the mobile terminal 23 has two charging coils. Judge that it was placed in between. Then, the control unit 10 also refers to the impedance change in the detection coil on both the left and right sides of the detection coil in which the maximum impedance change is detected (both sides in the detection coil arrangement direction).
