Optical storage-type electric vehicle wireless power supply system laid in highway and open environment

Abstract

The invention relates to the technical field of wireless charging of an electric vehicle, and particularly relates to an optical storage-type electric vehicle wireless power supply system laid in a highway and an open environment, which comprises the highway or a ground in the open environment, the electric vehicle, at least one charging system transmitting unit and an electric vehicle device receiving unit, wherein the charging system transmitting unit comprises a power supply module, a high-frequency inversion module, a pressure sensing device, an RFID reader, a power control circuit, a power oscillation module and an electromagnetic transmission coil connected in sequence; the electric vehicle device receiving unit comprises an electromagnetic receiving coil, an RFID electronic label, a rectifier module, a voltage-stabilizing step-down module and a vehicle-mounted battery connected in sequence; the high-frequency inversion module converts low-voltage DC to high-frequency AC; the at least one charging system transmitting unit is laid in the highway of the ground in the open environment to form a charging area; and the electric vehicle device receiving unit is arranged in the electric vehicle. The power supply system has a high energy utilization rate, and 24-hour uninterrupted power supply can be realized.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle wireless charging, and in particular relates to a light-storage type electric vehicle wireless power supply system used for laying roads and open-air environments. Background technique [0002] With the development of science and technology, environmentally friendly and energy-saving electric vehicles are playing an important role, but the popularization of electric vehicles still faces some problems. Especially the charging of electric vehicles is inconvenient. Therefore, the wireless charging method for electric vehicles has developed rapidly. The existing wireless energy transfer technology includes at least the following five directions: electromagnetic induction, electromagnetic resonance, microwave, ultrasonic and laser. The basic principle of electromagnetic induction is based on Faraday's law of electromagnetic induction. Its basic structure is similar to a transformer. There is ...
