On March 21, 2024, 2024 Asia will be held in the same period of Asia Charging ExpoWireless chargingThe conference was well received by the industryWPCWireless chargingShuang Yu, the liaison representative of the Alliance in Greater China, published《WPCQi2. 0 UnificationWireless chargingStandards.It mainly introducesWPCOverview, Qi ecosystemWPCOther important contents such as standards.
WPC was established in 2008 as an open and collaborative standard setting organization.There are nearly 300 company members all over the world, covering the entire supply chain.It launched the Qi standard, the world's first wireless kitchen power standard Ki, and is also developing light electric vehiclesWireless chargingStandards.
Qi ecosystem
Qi has been the world's leading global wireless charging standard for portable consumer electronics since 2010.The competition standards of the same kind also came out one after another, but soon disappeared.Qi is the only standard in the industry.Some OEM brands have built various proprietary enhanced solutions based on Qi, but this does not pose a problem in the market, because all products still support Qi standards.In 2020, a major consumer brand introduced a private wireless charging method that is not fully compatible with Qi, which caused market differentiation and confusion.Retail channels encounter problems in promoting and selling products to consumers, and consumers are confused about which products are compatible.
In this regard, the WPC Wireless Charging Alliance launched the Qi 2.0 version, which includes magnetic locking and re unifies the wireless charging standard of smart phones.After the launch of the standard, it is estimated that Qi will be in 2024/Qi2. 0 There will be about 340 million smart phones and more than 500 million wireless charging and transmitting devices in the market.
Qi v2.0 will be launched in the fourth quarter of 2023. At present, most new products apply for and pass the Qi v2.0 certification, not Qiv1.3.By the end of February 2024, about 450 original products are in the process of certification or have passed the Qi v2.0 certification.It is estimated that by the end of 2024,Qi2. 0 certified products will grow to about 1 billion devices.
Qi's future development roadmap, in 2025, WPC will bring Qi v2. X version, which is faster than 15W wireless fast charging.In the next few years, the WPC will focus on improving the power level of Qi standard.The private wireless charging scheme is easier to increase power than to formulate standards. The private protocol designer designs both transmitter and receiver devices.It is more difficult to develop standards for all products on the market, because standards need longer time to ensure safety, quality and compatibility.In the planning of new application fields of wireless charging from 2025 to 2027, such as smart watches.
Other WPC Standards
Home and industrial standards launched by WPC: one is Ki wireless kitchen, which is expected to be launched in 2024;The other is light electric vehicles. LEV has begun to formulate specifications.
The Ki v1.0 product is expected to be launched at the end of 2024, and the Ki standard will be launched before the product is launched.Ki v1.0 supports Ki dual purpose induction cooker, Ki independent transmitter, wireless charger with receiving coil.The subsequent Ki version will add support for concealed transmitters, wireless appliances with transponder coils, wireless stoves and other devices.
WPC LEV is a standard for light electric vehicles, including a wide range of standards. The initial standard is for electric bicycles and electric scooters.
The WPC hopes to make charging simple by formulating standards: unify charging methods and standards regardless of manufacturer and product model to bring convenience to consumers and users.
