Wherein, transducer is and the coil array coil voltmeter array that forms of M*N voltmeter one to one.

As shown in Figure 4, be the flow chart of a kind of wireless charging method embodiment 3 that the application provides, the method is realized by following steps:

Step S401: it is whole coil power supply in described coil array that described controller controls described power supply;

Step S401 is consistent with step S301 in embodiment 2, and the present embodiment repeats no more.

Step S402: described controller obtains the magnitude of voltage that in described voltmeter array, each voltmeter detects, the magnitude of voltage that described voltmeter detects is the magnitude of voltage at the coil two ends that described voltmeter is corresponding;

Wherein, the voltmeter in this voltmeter array and the coil one_to_one corresponding in this coil array, each voltmeter detects the magnitude of voltage at the coil two ends corresponding with it.

Wherein, this controller obtains the magnitude of voltage that each voltmeter in voltmeter array detects, and the mode of this acquisition can be used as carries out successively according to the sequence of row or row, does not limit in the present embodiment to the mode obtained.

It should be noted that, in concrete enforcement, the arrangement mode of this voltmeter array can be the arrangement mode arranged with the capable N of the on all four M of the arrangement mode of coil array coil, can adopt is not the arrangement mode that the capable N of M arranges yet, as a line, row, multirow or multiple row arrange all voltmeters, the information of each voltmeter is the position of the coil of its correspondence, available line number and columns are using the form of coordinate as the information of this voltmeter, information as a certain voltmeter is the position of coil in coil array that (2,3) this voltmeter is corresponding is the 2nd row the 3rd.

To sum up, in a kind of wireless charging method that the present embodiment provides, transducer is the array of detection units of S*R the detecting unit composition arranged in transmitting terminal, the value of described S and R be greater than 0 integer, the plane that described detecting element array is formed is overlapping with the plane that this coil array is formed, and the Detection Information that described controller obtains described transducer comprises: described controller obtains the detected value of each detecting unit in described array of detection units and the positional information of described detecting unit; The detected value of the arbitrary described detecting unit in described array of detection units and the positional information of described detecting unit combine by described controller, obtain the Detection Information of described detecting unit; Described controller obtains the Detection Information of each detecting unit in described array of detection units successively; Wherein, the Detection Information of described array of detection units characterizes the placement location in plane that described receiving terminal forms at described coil array.Adopt the method, the detected value of controller according to each detecting unit and the positional information of detecting unit, locate the state of each coil, and then control to provide electric current for the coil sections in coil array according to the state of this coil, the magnetic line of force produced to make this coil sections is crossing with the coil of this receiving terminal, and the coil of remainder is no longer powered, the situation that the energy non-receiving end coil of the magnetic field release excited when preventing this remainder coil power supply receives occurs, ensure that under the function prerequisite for receiving terminal charging, reduce the overall electric energy loss of transmitting terminal, improve charge efficiency.

As shown in Figure 8, be the flow chart of a kind of wireless charging method embodiment 5 that the application provides, the method is realized by following steps:

Step S801: described controller obtains a Detection Information;

Wherein, step S801 is consistent with step S201 in embodiment 1, and the present embodiment repeats no more.

Step S802: described controller, according to described Detection Information, obtains the placement location in plane that described receiving terminal forms at described coil array;

Wherein, this Detection Information is positioned over the Detection Information that produces in the plane formed at coil array for receiving terminal, and the placement location that this Detection Information can obtain in plane that this receiving terminal forms at coil array analyzed by controller.

Wherein, this step S802 specifically comprises: the detected value comprised in described Detection Information compares with predetermined threshold value by described controller, obtains comparative result; When described comparative result represents that described detected value is greater than predetermined threshold value, the magnetic line of force that the first coil that then described Detection Information is corresponding produces is crossing with the coil of described receiving terminal, and the position of the first coil described in described controller record is described receiving terminal covering position; Described controller, by position grouping corresponding for each the first adjacent coil, obtains the placement location in plane that described receiving terminal forms at described coil array.

It should be noted that, in the present embodiment, this Detection Information is detected by voltmeter and obtains, then this threshold value is voltage threshold, when this Detection Information is obtained by pressure sensitive unit detection, then this threshold value is pressure threshold, when this Detection Information is obtained by contact-sensing unit detection, then this threshold value is the numerical value whether difference has contact generation.

It should be noted that, the threshold value of this Detection Information is not limited in the present embodiment, in concrete enforcement, can arrange according to actual conditions.

Concrete, a threshold value is preset with in controller, when the detected value comprised in Detection Information is greater than this threshold value, the magnetic line of force produced during coil electricity corresponding to this detected value is crossing with the coil of receiving terminal, when the detected value comprised in Detection Information is less than this threshold value, the magnetic line of force produced during coil electricity corresponding to this detected value can not be crossing with the coil of receiving terminal.

It should be noted that, when the receiving end, region of a certain coil covers completely, the detection numerical value of its correspondence is larger, and when the non-receiving end, region of this coil covers completely, the detection numerical value of its correspondence is less, when the completely non-receiving end, region of coil covers, the detection numerical value of its correspondence is minimum.

In concrete enforcement, whether the coil that can arrange larger threshold value determination transmitting terminal is completely covered, and then gets rid of the coil of overlay area less (being completely covered).

It should be noted that, when a certain coil of transmitting terminal only has part receiving end to cover, only have the part magnetic line of force crossing with receiving terminal coil in the magnetic field then excited during this coil electricity, and remainder is not crossing with this receiving terminal coil, then the energy non-receiving end coil of this transmitting terminal release receives completely, and the charge efficiency of this coil is lower.
