Abstract

A bidirectional wireless charging/discharging device selectively performs electrical charging and discharging operation through selectively transmitting and receiving resonance energy with respect to a corresponding charging/discharging device that includes a second receiver/transmitter device. The bidirectional wireless charging/discharging device includes: a carrier body and a first receiver/transmitter device. The carrier body has a circumference from which an extension section extends. The first receiver/transmitter device is arranged inside the carrier body. The first receiver/transmitter device includes at least one connector, which is exposed outside the carrier body. The first and second receiver/transmitter devices selectively transmit to and receive from each other the resonance energy in a wireless manner and the resonance energy is then converted into electrical power, which is transmitted through the connector, or alternatively, the electrical power is converted into resonance energy for transmission and reception in a wireless manner.
