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 power supply efficiency is improved. Therefore, more electric vehicles can be charged.
本发明提供了电动汽车技术领域的一种充电方法及光储充系统,通过设置交流光伏发电系统、储能变流器以及电池储能系统,实现利用光能给电动汽车、电池储能系统充电,通过储能变流器将电池储能系统中的电能逆变给电动汽车充电,且通过能量管理系统创建的削峰填谷策略智能的给电池储能系统充电,限定交流配电柜输出的最高功率,最终实现在不增加电力配网压力的前提下,提升输出功率,即无需对电网进行扩容,无需对线路进行改造,便可增加充电桩的数量,进而给更多的电动汽车充电。
