14 Facts About Wireless charging
2.
Inductive Wireless charging is used in vehicles, power tools, electric toothbrushes, and medical devices.
| FactSnippet No. 794,031 |
3.
Inductive Wireless charging is named so because it transfers energy through inductive coupling.

4.
Greater distances between sender and receiver coils can be achieved when the inductive Wireless charging system uses resonant inductive coupling, where a capacitor is added to each induction coil to create two LC circuits with a specific resonance frequency.

10.
Electric vehicle wireless power transfer or wireless charging is generally divided into three categories: stationary charging when the vehicle is parked for an extended period of time; dynamic charging when the vehicle is driven on roads or highways; and quasi-dynamic or semi-dynamic charging, when the vehicle moves at low speeds between stops, for example when a taxi slowly drives at a taxi rank.

11.
The major advantage of the inductive approach for vehicle Wireless charging is that there is no possibility of electric shock, as there are no exposed conductors, although interlocks, special connectors and RCDs can make conductive coupling nearly as safe.
