Example Embodiment

[0019] The technical solutions provided by the present invention will be further described below in conjunction with the accompanying drawings.

[0020] In order to solve the technical problems existing in the prior art, the present invention adopts wireless magnetic coupling resonant charging, which is based on electromagnetic resonance theory. In this energy transmission technology, resonant coils with the same resonant frequency are arranged at the sending end and the receiving end. When the distance between the two is appropriate, the driving signal and energy at the same frequency as the resonant coil resonant frequency are sent to the sending end, and the two will resonate. The energy can be continuously transmitted from the sending end to the receiving end, the sending end consumes energy, and the receiving end absorbs energy, so that the wireless transmission of energy can be realized between the two devices. The advantage is the resonance technology with high Q value;...

Abstract

The invention discloses a solar-energy parking shed system capable of achieving wireless charging and discharging. The solar-energy parking shed system comprises a solar panel arranged at the top end of a parking shed, parking space charging and discharging devices and vehicular charging and discharging devices, wherein each vehicular charging and discharging device comprises a second magnetic coupling coil, a charging and discharging controller and a storage battery; each parking space charging and discharging device comprises an energy converter and a first magnetic coupling coil, and the energy converter is used for converting input electric energy into high-frequency electric energy which is output to the first magnetic coupling coil or converting the electric energy generated by the electromagnetic resonance coupling of the first magnetic coupling coil into alternating currents which are connected into a power grid; the first magnetic coupling coils and the second magnetic coupling coils are used for generating electromagnetic fields through electromagnetic resonance to receive or transmit electric energy. The solar-energy parking shed system has the advantages that the bidirectional energy storage inverter technology is used, solar energy resources are sufficiently first, and electric vehicles are charged through wireless magnetic coupling resonance; meanwhile, power grid stability is increased through the energy storage and peak, plain and valley regulating effects of the electric vehicles.

Description

technical field [0001] The invention relates to the application fields of solar power generation and electric vehicle wireless charging new energy, in particular to a solar wireless charging and discharging parking shed system. Background technique [0002] At present, electric vehicles are becoming more and more popular, and wired methods such as charging piles are usually used to charge electric vehicles. security risks and other issues. [0003] Wireless energy transmission technology is a brand-new power transmission technology, which has gradually matured technically and has become the focus of attention. As one of the three major technologies in the field of wireless energy transmission, the resonant magnetic coupling scheme can transmit several kilowatts of electric energy within a relatively long distance (for example, a few meters), and can be used for wireless charging of electric vehicles, thereby making up for the traditional contact charging method. of various...
