COMPOSITE-TYPE MAGNETIC COMPOSITE FOR CHARGING ELECTRIC TRANSPORTATION MEANS, PAD ASSEMBLY COMPRISING SAME, AND ELECTRIC TRANSPORTATION MEANS COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/154228
Kind Code:
A1
Abstract:
An embodiment relates to an assembled pad assembly characterized by comprising: a reception pad supporting a reception coil; the reception coil connected to the outside by a wire and positioned on the reception pad; and a magnetic composite layer disposed above or below the reception coil, wherein the amount of increase in inductance of the pad assembly after assembly relative to before assembly is 25 (%·cm3/g) or more per unit density of the magnetic composite layer. According to the embodiment, wireless charging with excellent charging efficiency is possible for electric transportation means, etc., and excellent charging efficiency can be well maintained even when an impact or repeated vibration is applied to the pad assembly.
