Electric vehicle charging piles are different from traditional gas stations and are generally installed in public places. The wide deployment of charging pile energy storage systems is of great significance to the development of smart grids. Through the demand side management, the effect of stabilizing grid fluctuations can be achieved.
The charging pile energy storage system can be divided into four parts: the distribution network device, the charging system, the battery charging station and the real-time monitoring system [ 3 ].
The main function of the control device of the energy storage charging pile is to facilitate the user to charge the electric vehicle and to charge the energy storage battery as far as possible when the electricity price is at the valley period. In this section, the energy storage charging pile device is designed as a whole.
The charging pile (as shown in Figure 1) is equivalent to a fuel tanker for a fuel car, which can provide power supply for an electric car.
