[0002] In recent years, the construction of new energy power stations has been changing with each passing day, and electric vehicles have become more and more popular in China. The explosive growth of electric vehicles has led to insufficient public charging facilities. Currently, charging facilities such as fast charging and super charging are used on the power supply side to alleviate the problem of difficulty in charging electric vehicles. Since car charging is a random load, it is very costly to solve the problem of limited distribution capacity from the power grid side. Therefore, electric vehicle photovoltaic storage charging stations have emerged.
