In order to respond to the call of Carbon Peaking and Carbon Neutrality and promote the integrated development of electric vehicles and green energy, this paper puts forward a green charging technology for electric vehicles based on the principle of photovoltaic storage and charging microgrid, specifically introduces the structure of this system, development status and future trend of photovoltaic storage and charging integrated charging station, and analyzes the case of specific projects. This study found that the photovoltaic storage and charging integrated charging station can balance energy production and energy consumption, output more stable external energy, reduce the pressure of the grid effectively, and improve power supply security. At the same time, it can reduce energy costs and improve energy efficiency. In the future, photovoltaic storage and charging integrated station is expected to be applied to business parks, residential communities, and other places on a large scale to achieve energy-saving and emission reduction effects and achieve the transformation of electric vehicle power sources to low-carbon and zero-carbon energy sources.
