The invention discloses a single-stage two-way wireless energy transmission system and method for an electric vehicle. The transmission system comprises a primary side switch network, a resonance network and a secondary side switch network. The transmitting end of the resonance network is connected to the output end of the primary side switch network, and the receiving end of the resonance network is connected to the output end of the secondary side switch network; the primary side switch network comprises a first full-bridge circuit; the bus capacitor is connected with the first full-bridge structure in parallel; the PFC inductor is connected to the input end of the full-bridge structure; the input end of the primary side switch network is connected to an alternating current power grid; the secondary side switching network comprises a second full-bridge circuit; the voltage stabilizing capacitor is connected with the second full-bridge circuit in parallel; the input end of the secondary side switch network is connected to a battery of the electric automobile; when the energy is forwardly transmitted, the battery at the secondary side switching network side discharges, and the primary side switching network outputs alternating current to an alternating current power grid; and when the energy is reversely transmitted, the primary side switching network provides alternating current, and the secondary side switching network charges the battery.
