The number of products that support the wireless charging function is constantly increasing due to the progressive spread of the technology. In a wide variety of sectors – automotive, medical technology or consumer electronics – the convenient technology for wireless charging of devices is now being used. Various approval requirements must be observed when placing devices supporting this technology on the market.
In addition to a possible certification based on the specifications of the Wireless Power Consortium (WPC), regulatory tests are mandatory for products with wireless charging function and serve as the basis for regulatory approval, which is a prerequisite for a successful market launch. For the European market, for example, the Radio Equipment Directive (RED) defines the test specifications for such products:
This standard, in its current version, provides a very detailed description of tests for WPT devices in terms of effective use of spectrum. The tests to be performed depend on the type of device (transmitter or receiver):
These standards cover requirements to ensure that EMC phenomena are properly addressed. The test scope can be roughly divided into two parts:
In addition, regulatory approval also requires compliance with electrical safety requirements based on the standards EN 62311, EN 60950-1 or EN 62368. Depending on the technical equipment of the actual device with regard to the technologies used (Bluetooth, WLAN, USB, NFC or mobile radio), additional regulatory test specifications must also be taken into account.
The regulatory requirements vary between the individual approval regimes. For a market approval in the USA, for example, FCC Part 18 and/or Part 15 serve as the basis for the regulatory tests.
