Abstract

A bidirectional wireless charging/discharging device includes: a first receiver/transmitter device and a second receiver/transmitter device. The first receiver/transmitter device includes a first power storage/supply device that supplies and converts a first electrical power into a first frequency modulation signal. A first resonant circuit device, when set in an activated state, receives and converts the first frequency modulation signal into first resonance energy. The second receiver/transmitter device is arranged to correspond to the first receiver/transmitter device. The second receiver/transmitter device includes a second resonant circuit device, which when set in a deactivated state, receives and converts the first resonance energy into a third frequency modulation signal. A second power storage/supply device receives the third frequency modulation signal, and converts the third frequency modulation signal into a third electrical power for storage. When the first resonant circuit device is set in a deactivated state and the second resonant circuit device is in an activated state, the second power storage/supply device supplies and converts a second electrical power into a second frequency modulation signal, which is received and converted by the second resonant circuit device into second resonance energy. The first resonant circuit device receives and converts the second resonance energy into a fourth frequency modulation signal. The first power storage/supply device receives and converts the fourth frequency modulation signal into a fourth electrical power for storage. As such, a function of bidirectional wireless charging and discharging is realized.
