FIELD: transport.
SUBSTANCE: invention relates to electrically driven vehicle and power feeder therefor. Proposed vehicle comprises secondary coil operating at natural resonance frequency, secondary coil, rectifier and power accumulator. Secondary coil operating at natural resonance frequency is configured for magnetic coupling with primary coil operating at natural resonance frequency of power feeder. Secondary coil is configured to receive electric power from secondary coil operating at natural resonance frequency via electromagnetic induction. In compliance with first version, power feeder comprises high-frequency power generator, primary coil to receive high-frequency power from high-frequency power generator, primary coil operating at natural resonance frequency, communicator and control device. Communicator is configured to receive magnitude of received power detection by vehicle. Control device is designed to adjust high-frequency power frequency. In compliance with another version, power feeder comprises device to control primary coil operating at natural resonance frequency, coil and control device. Control device detects received power at maximum level.
EFFECT: wireless power accumulation.
