FIELD: electronics.
SUBSTANCE: group of inventions relates to wireless charging of vehicle accumulator battery. Electric power supply device comprises communication means, notification means, detection means and control means. Communication means receives a trigger signal for activation of electric power supply device by means of wireless communication from vehicle. Notification means reports on state of electric power supply device. Detection means checks state of electric power supply device. Control means controls notification means based on detection result. Detection means checks state, in which power can be supplied from a coil for transmission of electric power via a contactless method. Control means controls notification means for reporting state, when non-contact power supply is possible, and state when not possible. Contactless electric power supply system also comprises a coil for receiving electric energy, which is installed on vehicle.
EFFECT: technical result is enabling determination of state of electric power supply device before parking vehicle.
