Wireless Charging Qi To Free Household Appliances From Power Cables
At the ongoing IFA 2024 exhibition, the Wireless Power Consortium (WPC) presented the final specifications of the Ki wireless charging standard, which is intended for use in home appliances and electronics.
Qi technology is a special coil that creates an electromagnetic field. It is captured by a receiver that can be built into a smartphone or other equipment. The current generation of the standard, Qi2, was introduced in 2023. In it, the developers improved the technology, increased the power to 15 W, and also added support for a universal magnetic mount. But progress did not stop there. The Ki standard is currently being prepared for launch. As noted by the WPC, such a standard will change the idea of kitchens.
Ki technology produces up to 2.2 kW of power. This is enough for almost any household appliance in the kitchen, including kettles or deep fryers. To turn on the device, you need to place it on the hob of an induction cooker that supports Ki. Thanks to this, the technology has many advantages. For example, you no longer have to plug devices into a socket and get tangled in wires. Electromagnetic fields prevent sparks, which reduces the risk of fire. And devices with Ki work when they are on special stations. If any device falls, it will immediately turn off – this is another plus for safety.
Since major home appliance manufacturers such as Philips, Midea and Miele are members of the WPC, it can be assumed that Ki-compatible appliances will appear on the consumer market as early as next year.
