1. Design of energy storage electric vehicle charging pile
The function of energy storage electric vehicle charging pile is similar to that of traditional automobile refueling, but the kinetic energy of automobile is replaced by clean electric energy.
The energy storage electric vehicle charging pile can be erected on the ground or fixed on the wall for a long time, and can also be installed in public places or public buildings, such as residential buildings, office buildings, large shopping malls, parking lots, etc. At the same time, it can charge various types of electric vehicles according to different voltage levels of the energy storage electric vehicle charging pile, which is convenient for residents. The current input end of the energy storage electric vehicle charging pile is directly connected to the AC power grid, and the output end is equipped with a matching charging plug for the owner to charge the electric vehicle
Energy storage electric vehicle charging piles generally have two charging methods, namely regular charging and fast charging. In the use process, people can swipe the card or perform the required operation on the operation interface provided by the energy storage electric vehicle charging pile through the specific charging card. The display screen of the energy-storage electric vehicle charging pile can display the charging amount, cost, charging time and other data of the owner’s electric vehicle, and can also print relevant data according to needs.
1.1 Hardware design
The charging pile of energy storage electric vehicle refers to the equipment specially designed for charging electric vehicles. The charging pile of the energy storage electric vehicle has the same function as the current gas station.
The charging pile of energy storage electric vehicle is divided into four parts: power distribution system, charging system, battery dispatching system and charging station monitoring system. According to the speed of charging, the way to charge the car can be generally divided into two types: ordinary charging and fast charging. The normal charging mode is generally AC direct charging for electric vehicles, which can be directly charged with 220 V or 380 V voltage. The fast charging method is to directly charge the electric vehicle with DC, which is faster and more convenient. The charging pile of energy storage electric vehicle mainly includes three parts: charging pile, active filter device and electric energy monitoring system.
In different charging modes, the slow charging pile inputs 220V AC to the car, and the charging is mainly completed by the on-board charger. It needs to be connected with a charging circuit, and the charging pile of the energy storage electric vehicle is connected with the electric vehicle communication circuit for charging. The charging equipment used is not large, so the slow charging pile does not have to be very large. The output of the fast charging pile is 380 V DC, which directly charges the battery pack, so the speed of charging the electric vehicle needs to be determined by the power of the pile. Slow charging and fast charging are different, no matter where, energy storage electric vehicle charging pile charging is the same. The relationship between different currents and DC buses is different. AC power grid and DC bus are mutually controlled relationship, battery pack and DC bus are mutually converted relationship, through the conversion of current into stored electrical energy for standby. The relationship between the energy storage battery pack and the DC bus is a communication relationship. Through the energy storage battery, users can charge with the energy storage battery pack when there is no energy storage electric vehicle charging pile.
1.2 Software design
In addition to the necessary hardware equipment, software equipment is also essential for the charging pile of energy storage electric vehicles. In the innovation and development of new energy sources, the storage of solar energy and light energy has become a hot word in the new energy industry, and “light storage” has gradually become the trend of new energy development. With the progress and development of science and technology, photovoltaic, energy storage and charging piles have become a power grid system. With the widespread application of energy-storage electric vehicle charging piles, the self-sufficiency of clean energy for electric vehicles can be realized, and a multi-complementary power generation system can be formed to maximize economic benefits. In addition, the energy-storage electric vehicle charging pile can effectively reduce and suppress the load impact of the power grid on the electric vehicle, reduce the line cost, and produce good social benefits. Energy storage electric vehicle charging piles are derived from electrical energy, and electrical energy cannot be replenished anytime and anywhere, so it is necessary to store electrical energy as much as possible when energy can be stored for emergency use.
With the development and advancement of time, the utilization rate of electric energy is gradually improved. In recent years, with the gradual popularization of energy-storage electric vehicle charging piles, people’s demand for electric energy is getting higher and higher, and clean energy gradually replaces traditional energy, becoming an inevitable trend in future development.
2. Experimental demonstration analysis
In order to ensure the validity of the proposed design method of charging pile for energy storage electric vehicles, experiments are carried out here. Experimental demonstration The same charging type with different storage performance of the charging post, energy storage electric vehicle charging post demonstration experiment. In order to ensure the rigor of the experiment, the traditional charging method is adopted, that is, the traditional charging plug is used to charge the electric vehicle, and then the proposed charging pile of the energy storage electric vehicle is used to charge the electric vehicle as an experimental demonstration comparison, and the charging speed and charging cost are counted. The experimental demonstration result curve is shown in the figure below.
The graph above represents the curve of charging time for two charging methods, where the horizontal axis is charging time and the vertical axis is charging amount, expressed as a percentage. As time progressed, the charge increased gradually. According to the figure, it can be concluded that the charging pile of the energy storage electric vehicle is obviously different from the charging of the traditional electric vehicle. At the beginning of charging, the charging method of energy storage electric vehicle charging pile has no obvious advantages, but in some environments, the proposed charging method of energy storage electric vehicle charging pile has obvious advantages. From the perspective of time consumption, the energy storage electric vehicle charging pile charging method has obvious advantages, especially when the charging time lasts for more than 9 hours, the energy storage electric vehicle charging pile charging method has outstanding advantages, which not only saves time and a lot of charging costs, but also protects the environment, saves energy, and reduces the loss and waste of electric energy. When charging an energy-storage electric vehicle charging pile, the real-time feedback of the data can be used to understand the amount of electric energy stored, and at the same time, the remaining amount of electric energy of the electric vehicle can be clearly understood, and the charging time can be effectively controlled. Compared with the traditional charging method, the proposed charging method reduces time and cost effectively.
