The inductive charging batteries have entered the market a few years: the practicality of recharge their equipment esonerando wires and sockets certainly has its practical side. If we add also the charm of minimalist forms and often futuristic, it is easy to understand how this type of technology you are confirming booming.
Upload induction batteries: what are the regulations governing the emissions testing of this product?
It depends.
Here's why.
The Wireless charghers is an electronic and electrical product whose functions can incorporate more skill.
E 'precisely the case of the wireless chargher which can lend itself to single charging function or also add the ability to transfer data: legislation to follow, however, is not unique, It varies from product functionality and the country of reference.
Here then before putting a product on the market, the process of the correct certification path must be more careful. There are more rules and guidelines to follow: in fact it is necessary to consider components, functionality and the final country to which the product is intended.
Statement on the Wireless Charger in USA
The FCC classifies wireless charger as a radiant body "intentional radiator".
The procedure for authorizing the placing on the market is that of certification.
The tests to be applied to the product are those established according to Title 47 of the Code of Federal Regulations FCC Part 15 and Part 18 (Specifically for devices “Wireless power transfer devices”).
Wireless Charges Regulations in CANADA
The radio standard specification RSS-216 published at the end of 2014 inherent in the wireless power transfer (Wireless charging batteries) It establishes minimum requirements for the wireless power transmission devices with power management and / or control capabilities. This standard distinguishes between three types of devices based on their classification as radios (Category I or II) or as interference-causing equipment, in particular industrial, scientific and medical equipment (ISM).
Wireless Charges Regulations in EUROPE
In Europe, the only inductive charging batteries is not considered a radio emitter and EMC tests to which refer for the certification are those arranged for the category of membership product.
If the inductive charging batteries is also designed to transmit data on the same frequency as the battery charge, then the product falls under the Direttiva RED (2014/53/EU) and the reference harmonized standards for certification is ON 300 330-2.
In order to adapt to these new technologies, the European Institute for Telecommunications Standards introduced in 2015, the Revision ETSI EN 300 330-2 v1.6.1.
The document is short generic range devices, transmitters inductive loop, radio equipment and devices for wireless energy transfer (fixed stations, Mobile and portable) and it distinguishes the procedures to be adopted depending on the number of the functionality of the product and the frequency used by these.
Safety Aspects
In all cases cited, without classification, if the product enters in the use of the domestic sphere, They must be carried out tests and analyzes in accordance with the harmonized standard IEC 60335 or to the corresponding European ones ON 60335-1 and ON 60335-2-6 which provide for the safety of electrical appliances for domestic use for kitchens, cookers, ovens and similar appliances.
Human exposure
Ultime ma non ultime, are to be considered the rules that regulate human exposure to electromagnetic fields.
Products must be in fact subjected to controls and tests on the radiation rate issued to preserve the health of harmful sources.
For example appliances, the harmonized standard applies ON 62233 “Measurement methods for electromagnetic fields of electrical household and similar apparatus with regard to human exposure” or the corresponding IEC 62233 for the USA.
How to obtain the CE mark
Given the complexity of the rules and the articulated harmonization, it is always advisable to consult a specialized laboratory for the verification of the product before placing it on the market.
For the Certification CE aspects shall be verified by compatibilità elettromagnetica, electrical safety, human exposure and good use of the spectrum according to Directive RED.
Once collected test reports, proving the success of all the measures carried out, and the product documentation, you can complete Technical documentation for the CE marking and draft Dichiarazione di conformità UE
Sicom Testing offers a complete service for the certificazione ce and authorization of electrical and electronic products for USA and Canada.

Good morning
For wireless charger (WPT) in China they will be limited to 50W, but the same thing will happen in Europe?
Good morning,
To date, European standards only place limits on the radiated electromagnetic field “at a distance” from the device but there is no limit on the power transmitted to the device being charged. The limit of 50 W for mobile phone chargers is currently being evaluated by international standardization bodies and in a few years it could also be present in European standardization.
Kind regards

Very interesting, good article. All very well described.
Good morning,
thanks for the comment. We are happy that our articles are helpful.
Cordial greetings

Good morning,
because of your article.
For wireless charger (WPT) there is ETSI EN 300 417 that seems centered on these devices. Why not apply this?
Thank you, Yours sincerely
It is actually a family of standards. In particular are standard non-harmonized, so do not give presumption of conformity to a directive.
Greetings and good work

Hi,
I read the article and I wonder if you can clarify some aspects.
Is it safe to carry in your clothes wireless phone charging cases? And powerbank wirelessly charging?
Thanks in advance
Hello Sandy,
thank you for writing us.
an assessment of human exposure is required for each solution. Both the electromagnetic field is the distance between the device and the human body must be measured. From these data we can calculate the human exposure. The product must be verified also for the general and / or electrical safety, Whereas if the product is used outdoors, and therefore subject to rain, fog, high and low temperatures.
Kind regards
