The invention provides an electromagnetic resonance wireless electric energy transmission system of an electric tour vehicle which operates at a tour and sightseeing fixed point. The electromagnetic resonance wireless electric energy transmission system comprises a wireless electric energy transmission circuit which is arranged on a parking charging point and a wireless electric energy receiving circuit which is mounted on the electric tour vehicle, wherein the wireless electric energy transmission circuit comprises a high frequency conversion power source and a wireless launch antenna resonance circuit; the wireless electric energy receiving circuit comprises a wireless receiving antenna resonance circuit, a high frequency rectifying circuit, a capacitor bank and a motor speed regulation module which are connected in sequence, and also comprises a receiving end voltage and current detection circuit. The design technology of the high-power low-frequency efficient electromagnetic resonance wireless electric energy rapid charging of an electric vehicle which operates at the fixed point and uses a super-capacitor for energy storage is adopted, and a switch device adopts a common IGBT (Insulated Gate Bipolar Transistor). For the electric vehicle which operates at the tour and sightseeing fixed point, the super-capacitor is adopted for energy storage, the high-speed charging at the fixed point is realized, the energy storage capacity is reduced, and the aims of reducing size, weight and cost are reached.
Description
technical field [0001] The invention relates to an electromagnetic resonance wireless power transmission system for an electric sightseeing car, in particular to an electromagnetic resonance wireless power transmission system for an electric sightseeing car with fixed-point operation for sightseeing. Background technique [0002] Electric vehicle wireless charging adopts non-contact power transmission technology. Currently, there are three commonly used wireless charging technologies: radio wave or microwave, electromagnetic induction and electromagnetic resonance. The radio wave type, because the magnetic flux radiates to the space in all directions, the power that can be received is very small; the microwave type is easy to cause interference to the communication, the energy beam is difficult to concentrate, the orientation is poor, and the transmission efficiency is low; the electromagnetic induction type is connected by magnetic field coupling induction , but the transmi...
