Abstract

The invention discloses a solar wireless electric vehicle charging station, which comprises a photovoltaic array device, a DC (direct-current) busbar device composed of a DC power distribution cabinet, a DC/DC converter, a high-frequency inverter and a wireless charging transmitting terminal, wherein the photovoltaic array device is connected with the DC/DC converter through the DC busbar device, the high-frequency inverter is connected with the DC/DC converter, and the wireless charging transmitting terminal is connected with the high-frequency inverter. Compared with the prior art, the solar wireless electric vehicle charging station has the advantages of achieving the purpose of charging an electric vehicle by a solar photovoltaic power generation system, avoiding the electric shock hazard and the electric energy consumption during charging operation of a plug by adopting a magnetically coupled resonance wireless charging technology, realizing an intelligentized charging technology as well as safety and convenience during charging of the electric vehicle, effectively reducing the capacity of a storage battery of the electric vehicle, lightening the self weight of the electric vehicle, reducing the manufacturing cost of the electric vehicle, improving the effective utilization rate of energy sources and promoting the development of the electric vehicle.

Description

technical field [0001] The invention relates to a charging system based on solar photovoltaic power generation, in particular to a solar wireless charging station for electric vehicles. Background technique [0002] The emergence of electric vehicles has effectively alleviated problems such as the oil crisis and environmental pollution. Electric vehicles are currently in their infancy, and the market has a small number of stocks. An important reason for the slow development of electric vehicles is that their charging infrastructure is not perfect. In major cities in China, only some demonstration projects have been installed, while in some small and medium-sized cities, there are even no electric vehicle charging stations. At present, the electric energy of electric vehicle charging stations in China mainly comes from thermal power, hydropower, nuclear power, etc., and still largely depends on primary energy such as coal, oil, and natural gas. Electric vehicles need to abso...
