What is QI certification for wireless charging? Presumably many manufacturers are not very familiar with Qi certification, so GTS Global One is here to talk about some related knowledge of wireless charging QI certification.

background

      In order to promote the widespread application of wireless charging technology worldwide, on December 17, 2008, mainstream wireless charging technology solution providers such as IDT, Qualcomm, Texas, etc., terminal product manufacturers and brand owners such as Samsung, Philips, etc., jointly initiated the establishment of wireless The wireless power consortium is WPC. These companies have also become the main regular members of WPC. On September 1, 2010, WPC entered China, hoping to promote its wireless charging standard among Chinese manufacturers.

      As the main means of promotion, WPC has introduced Qi certification rules, which stipulate product technical specifications, test specifications, certification procedures and the use of certification marks. Qi certification is currently mature and promoted. It is aimed at short-range electromagnetic induction low-power devices. In 2016, WPC has updated the standard, the updated version is 1.2.1, and the product certification of the old version 1.1.2 is no longer accepted. The new version of the standard already covers the 15W fast charging function of transmitting and receiving equipment.

      The certified and listed products not only meet the corresponding safety and performance specifications, but also the products of different brands and manufacturers are compatible with each other.
