Smart Cordless Kitchen Appliances at CES 2023 

There are a number of companies trying to market similar types of wireless power in the kitchen, however categories like this one need to have a standard to provide consumers the assurance of safety, reliability and interoperability. That's why major and start up kitchen appliance manufacturers around the world are joining the Wireless Power Consortium - to participate in developing the Ki Standard and carry the Ki logo on their products.

Indeed the dual-function hobs as displayed at CES2023 can do both standard cooking and Ki appliance powering on the same spot (of course not at the same time). In fact to enable the Ki powering, there is no user-action required on the hob. The appliance can be operated like a corded appliance. Placing the device on the hob will activate the power. Removing it will bring the hob in standby, meeting also standby power regulations and not transmitting any induction power while in standby.

And you will Manuel, but most likely not until the Ki Standard is available. It will be difficult for any individual company to successfully create a new category like this one without the existence of a standard to ensure consumers that the products are safe and interoperable with other brands in the market.

If I do not see it very safe because in the example of the mixer that starts it and removes it from the base then does not put it back. What happens if a child unintentionally places an appliance on top of it?

@@julianavarro3744 The software in the appliance will detect if a device was already switched on and then removed. Hence there is a safety precaution that a device that is in the "on-state" when placed on the power spot will not start until first switched off and then switched on again. It will also avoid your overfilled blender to start bursting like a volcano when placed on the spot and you might even trip it over because of it. The devices are designed to safely cope with such situations.

​@@julianavarro3744 my friend your vacuum cleaner work the same right? If you already have it switched ON before plugin it ????????????????

Wireless power transfer is not neccesarily inefficient. The higher the power, the better the efficiency. In this case the efficiency will be around 94%.

Any power conversion (also to power your phone via the charger or TV set) will have power conversion involving a transformer and those efficiencies in general are less than 90%.

@@r.dumont3031 Why does higher power result in higher efficiency?

@@gabedarrett1301 Because general system losses remain the same (constant factor; your car radio will not consume more power when driving at higher speed, nor will your car-system-management), and for lower powers these contributions are relatively higher.

No, the safety mechanisms built into the Ki standard prohibit the transmitter from being activated by anything other than a Ki-enabled appliance. That's one reason why a standard like Ki is critical in products like this.

The energy efficiency is around 94%

Great question. Indeed "at the surface" the Ki wireless power interface is identical, regardless whether the power generating device under the countertop is powered by 110 or 220v. Indeed the Ki appliances for 110V and 220V regions would be identical.

​@@r.dumont3031we would never wire these for 120V here in the USA, considering it's a professional install they would also be 240v like our stoves
