The processor is configured to: apply to the coils a ping signal of which a ping power section is repeated periodically and which has a plurality of ping power levels increasing in phases; confirm an SSP signal responding to the ping signal; and perform wireless power transmission by the coils on the basis of a ping power level in which the SSP signal is confirmed from among the plurality of ping power levels.",
