Automobile wireless charging coil shape classification

Wireless car charging coil shape is divided into 2 kinds, one is the circular coil,a square coil.

Wireless car charging coil shape determines the magnetic circuit, so the power supply side and receiving side shape is not united, between two coil cannotefficiently through the flux. Between the circular and square coils are not compatible with each other and have different advantages and disadvantages.The current global automobile manufacturers also basically divided into two factions.

Square coil is in a square flat ferrite core winding copper wire coil. Side outputflux from the inner core of the side plate, and then from another plate of the inner core into. The utility model has the advantages of large tolerance level ison the dislocation. But the leaked electromagnetic wave is often more severe.Because the flux is a side from beneath the plate within the core of the outputto the horizontal direction, and then from the top of the side plate of the inner core magnetic circuit to enter, so easy to disperse in the horizontal plane.Automobile wireless charging manufacturers through improved coverageoutside the coil installation etc., inhibit the dispersion problems of magnetic circuit.
