WIRELESS CHARGING SYSTEM CAPABLE OF ACHIEVING ENERGY FUNNEL EFFECT AND WIRELESS CHARGING METHOD THEREOF

WIPO Patent Application WO/2019/210503

A1

The present invention provides a wireless charging system capable of achieving an energy funnel effect and a wireless charging method thereof. The system comprises a wireless transmitting device and a wireless receiving device; the wireless transmitting device comprises a wireless transmitting control circuit and a wireless transmitting coil; and the wireless transmitting coil is electrically connected to the wireless transmitting control circuit; the wireless receiving device comprises a wireless receiving coil, a magnetic resonance excimer, a wireless transmitting control circuit, and a load; the magnetic resonance excimer is surrounded by the wireless receiving coil; the wireless receiving coil, the wireless transmitting control circuit, and the load are electrically connected in sequence; the plane turn area of the wireless receiving coil is less than that of the wireless transmitting coil, and on this basis, an energy funnel effect is achieved between the transmitting coil and the receiving coil; the transmission efficiency and transmission distance of a magnetic resonance wireless energy transmission system are improved, and a wireless charging system with better robustness and a charging method thereof are formed.
