A wireless charging system according to the present invention comprises: a first power reception device which is connected in parallel to a first battery and which includes a first sub-resonance circuit having a first resonance frequency; a second power reception device which is connected in parallel to a second battery and which includes a second sub-resonance circuit having a second resonance frequency; and a power transmission device. The power transmission device is configured to determine the charging order of the first battery and the second battery. If the first battery is selected according to the charging order, the power transmission device wirelessly transmits first alternating current power having the first resonance frequency to the first sub-resonance circuit. If the second battery is selected according to the charging order, the power transmission device wirelessly transmits second alternating current power having the second resonance frequency to the second sub-resonance circuit.

    Système de charge sans fil qui, selon la présente invention, comprend : un premier dispositif de réception d'énergie qui est connecté en parallèle à une première batterie et qui comprend un premier circuit de sous-résonance ayant une première fréquence de résonance; un second dispositif de réception d'énergie qui est connecté en parallèle à une seconde batterie et qui comprend un second circuit de sous-résonance ayant une seconde fréquence de résonance; et un dispositif de transmission d'énergie. Le dispositif de transmission d'énergie est conçu pour déterminer l'ordre de charge de la première batterie et de la seconde batterie. Si la première batterie est sélectionnée en fonction de l'ordre de charge, le dispositif de transmission d'énergie transmet sans fil une première énergie à courant alternatif ayant la première fréquence de résonance au premier circuit de sous-résonance. Si la seconde batterie est sélectionnée en fonction de l'ordre de charge, le dispositif de transmission d'énergie transmet sans fil une seconde énergie à courant alternatif ayant la seconde fréquence de résonance au second circuit de sous-résonance.

    본 발명에 따른 무선 충전 시스템은, 제1 배터리에 병렬 연결되고, 제1 공진 주파수를 가지는 제1 서브 공진 회로를 포함하는 제1 수전 장치; 제2 배터리에 병렬 연결되고, 제2 공진 주파수를 가지는 제2 서브 공진 회로를 포함하는 제2 수전 장치; 및 송전 장치를 포함한다. 상기 송전 장치는, 상기 제1 배터리 및 상기 제2 배터리 간의 충전 순서를 결정하도록 구성된다. 상기 송전 장치는, 상기 충전 순서에 따라 상기 제1 배터리가 선택된 경우, 상기 제1 공진 주파수를 가지는 제1 교류 전력을 상기 제1 서브 공진 회로에게 무선으로 송신한다. 상기 송전 장치는, 상기 충전 순서에 따라 상기 제2 배터리가 선택된 경우, 상기 제2 공진 주파수를 가지는 제2 교류 전력을 상기 제2 서브 공진 회로에게 무선으로 송신한다.
