The number of products that support the Qi standard, and thus the wireless charging function, continues to increase as the technology continues to expand. The number of companies registered with the WPC has increased by almost 100% in 2017 – with an ascending trend.
A Qi certification in accordance with the specifications of the Wireless Power Consortium (WPC) serves as a quality feature of the devices with wireless charging technology. Products that use the Qi standard must be rigorously tested to ensure safety, interoperability, and energy efficiency. Only products that pass these independent tests may use the Qi logo and are considered “Qi Certified”.
While regulatory testing is necessary and indispensable for the market approval of wireless charging devices, the Qi certification of the private Wireless Power Consortium is an additional component in the positioning of the product. Although Qi certification is not required by regulatory standards, the benefits of such approval in terms of product quality, interoperability and commercialization potential are undeniable.
Official Qi certification
As part of our services, we offer you a comprehensive portfolio in the context of testing wireless power transfer technology. In addition to a variety of regulatory approvals for global market entries, our laboratory in Essen, Germany is the only testing laboratory in Europe to offer certification exams according to various Qi profiles:
- BPP Baseline Power Profile (commonly called Low Power) for transmitters and receivers with up to 5 watts of power
- EPP Extended Power Profile (formerly referred to as Medium Power) for transmitter devices with a power of up to 15 watts
- Certification tests for the combination of Baseline Power Profile (commonly called Low Power) and FOD (Foreign Object Detection)
Due to the increased number of products on the market, the pressure for manufacturers to obtain approval in a timely manner in order to be present on the market is increasing. In this context, the relevance of pre-tests becomes ever greater.
Pre-testing can provide tremendous benefits to the approval process, both at the product development stage and shortly before the device is officially certified:
- In the context of development-supporting tests, indications of design improvements can be provided by results of the pre-tests. This particularly concerns the foreign object detection (FOD) and the maximum delivered/transmitted power, which is enormously relevant for wireless charging.
- Pre-testing saves manufacturers from surprises and possible delays due to unexpected results in the official certification tests, so there is no delay shortly before the planned launch.
- Pre-testing is possible without providing a wealth of formal information, so the administrative burden of performing pre-tests is low.
- Similarly, pre-testing already generates much technical and administrative information that can be used for the official certification process. Under certain circumstances, the formal effort involved in the official admission process may be reduced.
- The pre-tests can be used to look beyond the regulatory requirements. These checks are designed to identify worst-case scenarios and verify device interoperability.
Accordingly, pre-testing should not be underestimated as part of the approval of devices that use the Qi standards. Especially if the pre-tests are also carried out at an official Qi approval laboratory and all information and results can be reused.
We are therefore the ideal partner when it comes to the topic of wireless power transfer and can offer you all related services from a single source.
