Wireless power transfer (WPT) devices operating at frequencies above 9 kHz are intentional radiators and are subject to either Part 15 and/or Part 18 of the FCC rules. The specific applicable rule part depends on how the device operates, and if there is communication between the charger and device being charged.
Intentional radiators transmitting information must be certified under the appropriate Part 15 Rules and will generally require an equipment certification. A WPT device may operate in two different modes: charging and communications. It is possible for the device to be approved under Part 18 for the charging mode and Part 15 for the communications mode, if it can be shown that (1) the device complies with the relevant rule parts; and (2) the functions are independent. Part 18 consumer devices can be authorized using either certification or SDoC, once the appropriate RF exposure evaluation has been completed.
针对于工作频率高于9 kHz的无线能量传输设备,无线充电器的标准可以是FCC
传输信息的散热器必须根据相应的第15部分规则进行认证,并且通常需要设备认证。在FCC第15标准中,无线充电器做FCC认证,在FCC-SDOC中标准是PART15 B,在FCC-ID中标准是PART15C。
WPT设备可以以两种不同的模式操作:充电和通信。 如果可以证明(1)设备符合相关规则部分,则可以根据第18部分批准设备用于充电模式,第15部分用于通信模式; (2)职能是独立的。 一旦完成适当的RF暴露评估,第18部分消费者设备可以使用认证或SDoC进行授权。无线充电器做FCC认证充电模式可以做part 18标准, 通讯模式可以做part 15标准. 这两个标准都需要增加RF exposure evaluation。
