A charging pile, also known as a charging station or electric vehicle charging station, is a dedicated infrastructure that provides electrical energy for recharging electric vehicles (EVs) is similar to a traditional gas station, but instead of fueling internal combustion engines, it supplies electricity to recharge the batteries of electric vehicles.
Design of Energy Storage Charging Pile Equipment 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.
The charging pile determines whether the power supply interface is fully connected with the charging pile by detecting the voltage of the detection point. Multisim software was used to build an EV charging model, and the process of output and detection of control guidance signal were simulated and verified.

Combined with the fault degree, maintenance experience, and expert analysis of the charging pile, the state classification strategy is given. Each indicator of the charging pile is standardized according to the threshold level of the operating state.
The failure of the charging pile may be caused by many factors, the most common of which is the external environment and operation and maintenance frequency. Therefore, this paper constructs a potential fault identification model of electric vehicle charging pile from the above two aspects.
By the EFC algorithm, an EV selects a charging pile according to the following procedure. Step 1: At the beginning, the state information of all EVs and all charging piles in the system is sent to the scheduling center, as shown in Fig. 3, where a dotted line with a double arrow is used to indicate the data transmission.
