The distance between the two coils is typically 5 mm. It is possible to extend that range to at least 40 mm.[2] Regulation of the output voltage is provided by a digital control loop where the power receiver communicates with the power transmitter and requests more or less power. For a router, the sticker will be on the bottom.For more examples, click here. skipToContent skipToNavigation Home Wall Chargers ProductSupport Related Products. The base station sends an 8 bit data string. The competition between the members makes sure that performance increases, cost go down, and that more applications are served with solutions tuned to specific market needs. The power transfer then takes place using magnetic induction. Одна из них является базой и подключается к источнику энергии, а вторая находится внутри заряжаемого устройства и является приёмником.


The diagram also demonstrates that a Base Station may contain numerous transmitters, allowing for multiple Mobile Devices to be placed on the same Base Station and inductively charge until each of its batteries are fully charged. Once an object has been detected the base station validates the device placed on it for Qi charging compatibility. The current resultant from this voltage can charge a battery or power the device directly.While a moving magnet might just as well be used to externally generate the field, an external coil is simply more practical.

Close spacing of the two coils, as well as shielding on their surfaces, ensure the inductive power transfer is efficient. The Qi standard defines two ways of achieving this: Guided positioning: This form of placement on a Qi charger involves the use of means to guide the user to place the mobile in the correct place on the Qi base station for charging. The communications and control unit regulates the transferred power to the level that is appropriate for the subsystems (e.g., battery) connected to the output of the power receiver.
