2. Inductive charging - Wikipedia

   en.wikipedia.org/wiki/Inductive_charging

   Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices. The portable equipment can be placed near a charging station or inductive pad without needing to be precisely aligned or make electrical contact with a dock or plug. Inductive charging is named so because it transfers energy through inductive ...

3. Qi (standard) - Wikipedia

   en.wikipedia.org/wiki/Qi_(standard)

   Qi (pronounced / tʃ iː / CHEE; [1] from simplified Chinese: 气; traditional Chinese: 氣; pinyin: qì) is an interface standard for wireless power transfer using inductive charging. The standard allows compatible devices, such as smartphones , to charge their batteries when placed on a Qi charging pad, which can be effective over distances ...

4. Wireless power transfer - Wikipedia

   en.wikipedia.org/wiki/Wireless_power_transfer

   Its Qi inductive power standard published in August 2009 enables high efficiency charging and powering of portable devices of up to 5 watts over distances of 4 cm (1.6 inches). [173] The wireless device is placed on a flat charger plate (which can be embedded in table tops at cafes, for example) and power is transferred from a flat coil in the ...

6. SAE J2954 - Wikipedia

   en.wikipedia.org/wiki/SAE_J2954

   [a] A much more powerful WPT9 is being defined in J2954/2 for 500 kW charging for heavy-duty vehicles which have the room necessary to mount the larger induction plate. [2] The system works along similar principles as inductive charging, but uses the resonant inductive coupling concept with a demonstrated efficiency of around 85%. This makes it ...

7. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   A charging station sends electromagnetic energy through inductive coupling to an electrical device, which stores the energy in the batteries. This is achieved without the need for metal contacts between the charger and the battery. Inductive battery chargers are commonly used in electric toothbrushes and other devices used in bathrooms. Because ...
