Title
(EN) WIRELESS CHARGING SYSTEM WITH START-UP NEGOTIATION
(ZH) 具有启动协商的无线充电系统
Abstract
(EN) A wireless power transmission system has a wireless power receiving device that is located on a charging surface of a wireless power transmitting device. The wireless power transmitting device uses measurement circuitry such as coil impedance measurement circuitry or impulse-response circuitry that makes coil inductance measurements to monitor the charging surface for the presence of the wireless power receiving device. In response to detecting that the wireless power receiving device is present on the charging surface, the wireless power transmitting device and the wireless power receiving device establish a wireless communications link. The wireless power transmitting device transmits information on wireless power transmission capabilities of the wireless power transmitting device to the wirelessly power receiving device. The receiving device selects desired settings and transmits these to the transmitting device.
(ZH) 本公开涉及具有启动协商的无线充电系统。本发明公开的无线功率传输系统具有无线功率接收装置,所述无线功率接收装置位于无线功率传输装置的充电表面上。所述无线功率传输设备使用测量电路诸如线圈阻抗测量电路或进行线圈电感测量的脉冲响应电路以监视所述充电表面是否存在所述无线功率接收设备。响应于检测到所述无线功率接收设备存在于所述充电表面上,所述无线功率传输设备和所述无线功率接收设备建立无线通信链路。所述无线功率传输设备向所述无线功率接收设备传输关于所述无线功率传输设备的无线功率传输能力的信息。所述接收设备选择所期望的设置并将这些设置传输给所述传输设备。
