The wireless charging apparatus includes a plurality of coil arrays disposed so as to partially overlap each other, and a shielding member disposed at one side of each of the coil arrays to block a leaked magnetic field. The coil arrays include a first coil array including a plurality of transmission coils disposed adjacent to each other, a second coil array including a smaller number of transmission coils than the first coil array and disposed under the first coil array, and a third coil array including the same number of transmission coils as the second coil array and disposed on the first coil array. As a result, it is possible to simultaneously charge a plurality of devices requiring different amounts of power."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless charging apparatus","description":"A wireless charging apparatus is disclosed.
