在实际应用中，无线充电接收端发送实时无线充电功率至无线充电发射端的方式，可以是在通过双向连接接收到无线充电发射端的功率请求后，获取并发送，也可以在开始无线充电后，主动上报。
S103：无线充电发射端接收来自无线充电接收端的实时无线充电功率，根据实时无线充电功率及实时发射功率，计算实时无线充电传输效率，根据实时无线充电传输效率及理想无线充电传输效率，计算实时充电耦合系数，显示实时充电耦合系数；
在实际应用中，如图4所示，无线充电发射底座通过功率电路进行能量发射，同时通过解调电路获取接收端RX的发送信息，给到MCU进行分析然后进行无线充电的相关调整；在无线充电发射端增加一个耦合状态指示条，由多颗LED发光灯组成；通过手机端发送从充电器端接受到的功率数据Pr，无线充电器端可以实时统计自身的发射功率Pt，两者的比例µ=Pr/Pt。通过测试验证，无线充电完全配合好的效率为µ0，那么系统根据耦合系数β=µ/µ0的值进行耦合状态显示。具体的，当完全耦合时指示条全部显示绿色，如图6所示；否则根据耦合程度系数显示，如果耦合程度80%，则显示如图7所示。
在一实施例中，上述实施例的无线充电控制方法在无线充电接收端的体现包括：
接收无线充电电波，进行无线充电；

在实际应用中，无线充电发射端可以支持多个手机等设备同时充电，如图9所示，可以同时支持两个手机充电，那么对应的，可以为2个充电线圈分别设置耦合状态指示条及最佳位置引导框；针对通信装置及处理器，可以多个充电线圈公用，也可以为各充电线圈单独设置，在多个充电线圈公用时，需要根据无线充电接收端设备的设备标识，确定对应的充电线圈。
实施例四：
现结合具体应用场景对本发明做进一步的诠释说明。
本实施例考虑到目前的WPC无线充电产品的使用指导性不强，在无线充电器端增加状态指示，根据发射端和接受端的功率情况，计算目前发射端和接受的传输效率，与理想值进行比较，可以实时显示无线充电的耦合程度。完全对齐时显示100%或者满色状态，没有对齐时，根据与理想值比例差距显示对应的百分比或者半色状态，这样用户就能判断出位置是否放在了最佳位置，便于急需充电时可以保证最佳的充电效率。
WPC无线充电是通过磁场进行能量传输，同时又借助磁场波形进行幅度调制，将需要通讯的内容加载在传输波形上。如图4所示，无线充电发射底座通过功率电路进行能量发射，同时通过解调电路获取接收端RX的发送信息，给到MCU进行分析然后进行无线充电的相关调整。
如图6及7所示，本实施例在无线充电发射端增加一个耦合状态指示条，由多颗LED发光灯组成。
本实施例提供的无线充电控制方法如图5所示，具体步骤不再赘述，该方法通过手机端发送从充电器端接受到的功率数据Pr，无线充电器端可以实时统计自身的发射功率Pt，两者的比例µ=Pr/Pt。通过测试验证，无线充电完全配合好的效率为µ0，那么系统根据耦合系数β=µ/µ0的值进行耦合状态显示。
如图6所示，当完全耦合时指示条全部显示绿色；否则根据耦合程度系数显示，如果耦合程度80%，则显示如图7的状态。
本实施例通过增加无线充电器发射端的耦合程度指示条，根据无线充电的发射和接受的功率情况，在无线充电实时显示发射端和接受端的耦合程度，提示用户目前的对齐程度，保证用户在进行无线充电时可以通过状态指示情况将手机放到最佳位置，保证最高充电效率。
通过以上实施例的实施可知，本发明提供的方法具备以下有益效果：

以上内容是结合具体的实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
