Induction battery chargers: how to certify them in Europe, USA and Canada

Induction battery chargers have entered the market for a few years: the convenience of recharging your device by eliminating wires and sockets certainly has its practical side. If we also combine this with the charm of minimal and often futuristic shapes, it is easy to understand how this type of technology is proving to be in full expansion.
Induction battery charger: what are the regulations governing the verification of emissions of this product?
Depends.
Let's see why.

Wireless chargers is an electronic and electrical product whose functions can incorporate multiple abilities.
This is precisely the case of the wireless charger which can lend itself to the charging function alone or also add the ability to transfer data: the legislation to be followed, however, is not unique, it varies depending on the functionality of the product and the country of reference.

Therefore, before placing a product on the market, the process of the correct certification path must be more careful. There are more regulations and directives to follow: it is necessary to consider components, functionality and the final country for which the product is intended.

Wireless Charger Regulations in the USA

The FCC classifies the wireless charger as an "intentional radiator".
The procedure to be followed for marketing authorization is that of certification.
The tests to be applied to the product are those envisaged in accordance with Title 47 of the Code of Federal Regulations FCC Part 15 and Part 18 (Specifically for “Wireless power transfer devices”).

Regulations on Wireless Charges in CANADA

Vehicle charger

There radio standard specification RSS-216 published in late 2014 regarding Wireless Power Transfer (Wireless Battery Charging) establishes minimum requirements for wireless power transmission devices with power management and/or control capabilities. This standard distinguishes between three types of devices based on their classification as radio equipment (category I or II) or as interference-causing equipment, in particular industrial, scientific and medical (ISM) equipment.

Regulations on Wireless Charges in EUROPE

In Europe the induction battery charger alone is not considered a radio emitter and the EMC tests to refer to for certification are those arranged for the product category to which it belongs.
If, however, the induction battery charger is also designed to transmit data on the same frequency as the battery charger, then the product falls under the Directive RED (2014/53/EU) and the harmonized reference standard for certification is the EN 300 330-2.

With the aim of adapting to these new technologies, the European Institute for Telecommunications Standards introduced in 2015, the ETSI EN 300 330-2 V1.6.1 revision.
The document deals with generic short-range devices, inductive loop transmitters, radio equipment and wireless energy transfer devices (fixed, mobile and portable stations) and distinguishes the procedures to be adopted depending on the number of product features and of the frequency used by them.

Security aspects

In all cases mentioned, without distinction of country, if the product enters domestic use, tests and analyzes must be carried out in accordance with harmonized standards IEC 60335 or to the corresponding European ones EN 60335-1 and EN 60335-2-6 which provide for the safety of household electrical appliances for kitchens, stoves, ovens and similar appliances.

Human exposure

Last but not least, the regulations that regulate human exposure to electromagnetic fields must be considered.
The products must in fact be subjected to controls and tests on the rate of radiation emitted to preserve health from harmful sources.
For household appliances, for example, the harmonized standard applies EN 62233 “Methods of measurement for electromagnetic fields of household electrical appliances and similar with reference to human exposure” or the corresponding IEC 62233 for the USA.

How to obtain the CE mark

Given the complexity of the regulations and the detailed harmonization, it is always advisable to contact a specialized laboratory to verify the product before placing it on the market.
For the Certification CE the aspects of electromagnetic compatibility, electrical safety, human exposure and good use of the spectrum must be verified according to the RED Directive.
Once the test reports have been collected, proving the successful outcome of all the measurements carried out, and the product documentation, the project can be completed. Technical file for CE marking and write the EU declaration of conformity

  1. Good morning
    Wireless chargers (WPT) in China will be limited to 50W, but will the same thing happen in Europe?

    • Good morning,
      To date, European standards place limits only on the electromagnetic field radiated "at a distance" from the device but there is no limit on the power transmitted to the device being charged. The 50W limit for mobile phone chargers is currently being evaluated by international standardization bodies and could also be present in European standardization in a few years.

  2. Good morning,
    thanks for your article.
    For wireless chargers (WPT) there is the ETSI EN 300 417 which seems to be centered on these devices. Why not apply this?

    Thank you

    • It is actually a family of standards. In particular, they are non-harmonised standards, therefore they do not give presumption of conformity to a directive.

  3. 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 power bank wirelessly charging?

    Thanks in advance

    • Good morning Sandy,

      thank you for writing us.
      A human exposure assessment is required for each solution. Both the electromagnetic field and the distance between the device and the human body must be measured. From this data human exposure can be calculated. The product must also be checked for general and/or electrical safety, considering whether the product is used outdoors, and therefore subject to rain, fog, high and low temperatures.
