Photovoltaic-powered street lamp type wireless charging pile for electric automobiles

Abstract

The invention discloses a photovoltaic-powered street lamp type wireless charging pile for electric automobiles, which comprises a power supply terminal, a wireless sending terminal and a wireless receiving terminal, wherein the power supply terminal comprises a photovoltaic array and an electric network source which are arranged at the top of a street lamp, and the photovoltaic array is connected with an energy storage battery through a DC (Direct Current) junction station; the wireless sending terminal comprises a main MCU (Microprogrammed Control Unit), a rectifier filter, a DC-DC converter, a high-frequency inverter and a wireless transmitting coil, and the output end of the energy storage battery and the electric network source are connected with the rectifier filter, the DC-DC converter, and the high-frequency inverter through an intelligent selector switch to output high-frequency electromagnetic power and then the high-frequency electromagnetic power is loaded onto the transmitting coil; the intelligent selector switch, the rectifier filter, the DC-DC converter and the control end of the high-frequency inverter are connected with the output end of the main MCU, and the wireless receiving terminal comprises a wireless receiving coil; the wireless receiving coil and the transmitting coil are arranged in a magnetic resonance way, and the received high-frequency electromagnetic signals are stepped down by a high-frequency step-down transformer and rectified by a rectifier and then are output to a working battery of an electric automobile.

Description

technical field [0001] The invention relates to the field of charging piles for electric vehicles, in particular to a street lamp-type wireless charging pile for electric vehicles based on photovoltaic power supply. Background technique [0002] Electric vehicle charging stations refer to stations that charge electric vehicles, similar to gas stations today. With the low-carbon economy becoming the main theme of my country's economic development, electric vehicles, as an important part of the new energy strategy and smart grid, and one of the strategic emerging industries determined by the State Council, will surely become the focus of the development of China's automobile industry and energy industry in the future . At present, the main charging methods of electric vehicles include charging piles for ordinary charging, charging stations for fast charging and battery swapping stations. However, these three methods have certain disadvantages, but the common defect is: the co...

AI Technical Summary

Problems solved by technology

However, these three methods have certain disadvantages, but the common defect is: the common standard problem of wired connection

Most of the fast charging methods are DC charging, which takes tens of minutes for a single charge, and fast charging will reduce the service life of the battery, and the impact on the urban power grid cannot be ignored

The main problems in the way of battery replacement include the standardization of batteries for electric vehicles, the management of battery circulation, etc.
