Charging method and optical storage charging system

The invention provides a charging method and a light storage and charging system in the technical field of electric automobiles, by arranging an alternating-current photovoltaic power generation system, an energy storage converter and a battery energy storage system, the electric automobiles and the battery energy storage system are charged by utilizing light energy, and electric energy in the battery energy storage system is inverted through the energy storage converter to charge the electric automobiles. And the battery energy storage system is intelligently charged through a peak clipping and valley filling strategy created by the energy management system, and the maximum power output by the alternating current power distribution cabinet is limited, so that the output power is improved on the premise of not increasing the pressure of the power distribution network, that is, the number of charging piles can be increased without expanding the capacity of the power grid and transforming the line, and the powe
