680106 D01 RF Exposure Wireless Charging Apps v03r01
Question: What rules regulate short distance wireless inductive coupled charging pads or charging devices? 什么规则规范短距离无线感应耦合充电板或充电设备？
Answer:
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.
Devices specifically intended for use for wireless power transfer, or inductive charging, require FCC guidance for frequency exposure review. This includes Part 18 devices. It may be necessary for the responsible party (manufacturer) to seek guidance from the FCC on specific WPT devices by submitting a KDB inquiry.
以高于 9 kHz 的频率运行的无线电力传输 (WPT) 设备是故意辐射器，受 FCC 规则第 15 部分和/或第 18 部分的约束。 具体适用的规则部分取决于设备的运行方式，以及充电器和被充电设备之间是否存在通信。专门用于无线电力传输或感应充电的设备需要 FCC 指导以进行频率暴露审查。 这包括第 18 部分设备。 责任方（制造商）可能需要通过提交 KDB 查询来寻求 FCC 对特定 WPT 设备的指导。
The inquiry should include the following:
- complete product description, including coil diameters , number of turns and current; 完整的产品描述，包括线圈直径、匝数和电流
- FCC Rule Part(s) the device will operate under and the basis for selecting the Rule Part(s); 设备将在 FCC 规则部分下以及选择部分规则下运行的依据
- planned equipment authorization procedure (i.e., SDoC or certification); 计划的设备授权程序（即 FCC SDoC 或FCC ID认证）
- drawings, illustrations; 图纸、插图；
- frequency of operation; 工作频率
- radiated power; 辐射功率
- operating configurations; and 操作配置
- conditions for human exposure. 人体接触情形与条件，例如，使用的时候必须直接接触人体、距离人体距离多少、接触身体部位，身体、手部，以及不需要接触人体等情况。
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.
传输信息的有意散热器必须根据适当的第15部分规则进行认证，通常需要设备认证。WPT设备可在两种不同模式下工作：充电和通信。如果能够证明
（1）该装置符合相关规则部分的规定，则该装置可以根据第18部分的规定获得充电模式认证，根据第15部分的规定获得通信模式认证；
（2）功能是独立的。一旦完成适当的射频暴露评估，可使用认证或SDoC对第18部分消费类设备进行授权。
Finally, it is possible that the power charging function could be approved under Part 15 rather than Part 18 if the device meets all of the requirements of the appropriate Part 15 rule.
Attachment 680106 D01 RF Exposure Wireless Charging Apps v03r01 provides general guidance on the information necessary to determine RF exposure evaluation and compliance requirements when submitting a wireless charging application inquiry.
最后，如果设备满足第15部分规则的所有要求，则可以根据第15部分而不是第18部分批准充电功能。
附件680106 D01射频暴露无线充电应用程序v03r01提供了在提交无线充电应用程序查询时确定射频暴露评估和合规性要求所需信息的一般指南。
