Qi certification: the universal language of the Wireless charging world Qi, the full name of the Wireless charging Consortium (Wireless Power Consortium, referred to as WPC) masterpiece, it defines a universal wireless charging standard. This standard is "convenient" and "universal" as the core, ensuring that different brands of products only need to have the Qi logo, can be seamlessly connected with any QI-compatible wireless charger.
Qi is the Wireless Power Consortium, referred to as WPC) launched "wireless charging" standard Car wireless charging sample ; It has two characteristics of convenience and versatility. Qi certification test standard Qi standard 0 was released in July 2010, the current version is V4, the WPC charging Alliance expects the latest version V3 around April 2020 (there is likely to be a 3-6 month delay), the full V3 specification was released in WPC2001.
Wireless charging Qi certification types can be divided into three categories: BPP certification, EPP certification and PPDE recognitionCertificate. 1) QI-BPP certification: The product supports less than 5W power, the use of Qi protocol, must be BPP certification. 2) QI-EPP certification: The product supports more than 5W power, the use of Qi protocol, must be EPP certification. 3) Qi-PPDE certification: The product supports more than 5W power, uses Samsung private protocol PPDE, and must be tested by PPDE (from July 1, 2019).
Wireless charging Qi certification content: including Compliance test (Compliance test) and compatibility test (Interoperabi)We will actively carry out strategic layout and seize opportunities to cut into the market.

QI certification is the Wireless Charging Alliance certification, that is, WPC certification (Wireless? The Power? The Consortium is a collaborative group of independent companies that aims to create and promote widespread market adoption of Qi, an international wireless charging standard compatible with all rechargeable electronic devices. QI certification is an authorized mark for wireless charging products, and only products that have been rigorously tested to ensure safety, interoperability and energy efficiency can use the QI certification mark.
QI authenticationIs the Wireless charging Alliance certification, formerly known as WPC certification is the first letter of the Wireless Power Consortium (Wireless charging Alliance), which belongs to a technical organization's certification requirements, similar to SIG's Bluetooth BQB certification. It is not directly related to conventional national or regional certification, that is to say, it can be used globally.
This certification is a certification that complies with the wireless charging standards established by the Wireless Charging Alliance (WPC). Qi certification refers to the certification that meets the wireless charging standards set by the Wireless Charging Alliance (WPC). wirelessThe Charging Alliance (WPC) is a global organization dedicated to developing and promoting standards for wireless charging technology.

qi certification is WPCProducts certified by the WPC Alliance can use the QI certification mark, which is similar to the BQB certification of the Bluetooth Alliance. Up to now, the wireless charging alliance WPC has more than 600 members, more than 800 products have obtained QI certification, WPC has an absolute advantage in the field of wireless charging standards.
1. In theoryElectric vehicle wireless charging technology can not only greatly improve the user's car experience, but also pave the way for the last link of the unmanned future autonomous driving use scenario. One of the important reasons for the delay in really going to the market is that various countries failed to develop a unified standard for the technology as soon as possible, resulting in a series of "chain reactions", resulting in difficult to scale, marketization.
2, then to say that the wireless charging used by the passenger car before, the power is not as efficient as the slow charging pile, and the current level can exceed the slow charging efficiency. From this point on, wireless charging has beenQualified to load the car. However, the application of wireless charging technology to the field of new energy vehicles seems to be a very worthwhile thing, but the specific research and development process has encountered a number of problems.
3, secondly, wireless charging power is low and the cost is high. The current passenger car wireless charging power is up to 11kW, the efficiency is lower than wired charging, the equipment cost is more significant, a 3kW wireless charging system price of more than 10,000, and the same efficiency of AC slow charging pile only more than 1,000. The high cost and low efficiency make the popularization of wireless charging technology face serious challenges. Moreover, wireless charging brings electromagnetic wavesThe radiation problem cannot be ignored.
