Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices.
The Level 2 charger which supplied 6.6 kW was the most common version. A higher-power (Level 3) "fast charge" version which supplied 50 kW was demonstrated in 1998. [14] There were two inductive charge paddle sizes, an original large paddle and later small paddle, which were 5 + 1 ⁄ 2 and 4 + 1 ⁄ 4 in (140 and 110 mm) wide, respectively. [15]
Inductive charging pad for a smartphone as an example of near-field wireless transfer. When the phone is set on the pad, a coil in the pad creates a magnetic field [1] which induces a current in another coil, in the phone, charging its battery. Generic block diagram of a wireless power system
The car will only charge at around 1 or 2 kW, which is five times slower than a home wallbox-style charger, and more than 100 times slower than what many electric cars are capable of.
Non-contact charging utilizes magnetic resonance to transfer energy in the air between the charger and battery. This achieves a highly efficient energy transformation. [7] As the non-contact charger could keeping charging the vehicle, it allows EVs to have a smaller battery. By itself, it is more economical, safer and more sustainably developed.
A simple charger typically does not alter its output based on charging time or the charge on the battery. This simplicity means that a simple charger is inexpensive, but there are tradeoffs. Typically, a carefully designed simple charger takes longer to charge a battery because it is set to use a lower (i.e., safer) charging rate.

Resonant inductive coupling or magnetic phase synchronous coupling [4] [5] is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. [5]
