無線充電器是指不用傳統的充電電源線連接到需要充電的終端設備上的充電器,采用電磁感應原理,通過線圈進行能量耦合實現能量的傳遞。從理論來說,無線充電技術對人體(tǐ)安全無害處,無線充電使用的共振原理是磁場共振,隻在以同一(yī)頻(pín)率共振的線圈之間傳輸,而其他裝置無法接受波段。但是它在正常工(gōng)作下(xià)會産生(shēng)電磁場,所以也要滿足相應的EMC要求。
1、無線充CE認證标準:
R&TTE指令中(zhōng),ETSI針對無線充電器在EN300 330-1 V1.8.1中(zhōng)有章節規定:
新的RED已經将無線充電器劃分(fēn)到了EN303 417. 适用的範圍如下(xià):
Note: 無線充電器一(yī)定要有Radio Communication or Radio Determination功能才屬于EN303 417的範疇。如果僅僅是充電功能的話(huà),那麽就應該符合EMCD。
2、無線充FCC認證标準(KDB680106 D01):
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.
無線充電器的标準可以是Part 15C或Part 18,取決于充電設備和接受充電的設備之間是否有通訊。
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.
充電模式可以做Part 18,通訊模式可以做Part 15C.這兩個标準都需要增加RF exposure evaluation。
3、無線充IC認證标準:
