Ki (wireless charging standard)

2024: Standard Approval

In mid-September 2024, the Wireless Electromagnetic Energy Consortium (WPC) announced the approval of a new wireless charging standard for Ki appliances that would allow small kitchen appliances such as toasters and blenders to operate without a power cable.

The new Ki standard uses electromagnetic induction to wirelessly transfer energy to devices, but differs from the previously implemented Qi standard. In the case of Qi, the energy from the wireless charger is used only to charge the battery of the mobile device, and in the Ki standard, the generated current is used to directly power the motors, heating elements and electronics that ensure the operation of the device.

The Verge

In addition, kitchen appliances require significantly more energy than the battery of a mobile device. Qi and Qi2 standards can provide up to 5 and 15 watts of power, respectively, and the Ki standard, thanks to the use of much larger coils, can transmit up to 2200 watts of power. This is more than enough even for energy-intensive devices such as fryers.

The Ki can also wirelessly transmit energy through materials such as granite, quartz, marble and even wood up to 5cm thick, allowing discreetly m wireless energy transmitters into the kitchen.

Ki-compatible devices interact with NFC power transmitters, and power will be supplied to them only when the device is safely used. If the blender capsizes, the power supply will turn off immediately. In addition, the lower part of the appliances or the surface of the countertop will not be able to heat up to such an extent as to cause burn or damage to adjacent materials.^[1]
