The ownership of private charging piles determines whether users can charge at home and the demands for public charging resources. Currently, the ownership rate of private charging piles among the studied EVs in Beijing is about 80 %, and it is assumed that the ownership rate will increase by averagely 5 %/year by 2025.

Energy storage systems can solve this problem in a simple and elegant way. We use fluids like petrol or gasses to store energy and reuse it when needed (for example, when fueling a car). With the same principle, we can store electric energy in batteries using electrons and chemistry. This energy can be then utilized to boost an EV charge to keep the grid stable by shaving the
1. AC slow charging: the advantages are mature technology, simple structure, easy installation and low cost; the disadvantages are the use of conventional voltage, low charging power, and slow charging, and are mostly installed in residential parking lots. 2. DC fast charging: the advantage lies in the use of high voltage, large charging power, and fast
The first is that top-down public charging pile planning relies on parking lot construction, and most cities currently lack sufficient parking lot construction. At this stage, the overall number of public charging stations and the proportion of vehicle piles are insufficient.

Fig. 13 compares the evolution of the energy storage rate during the first charging phase. The energy storage rate q sto per unit pile length is calculated using the equation below: (3) q sto = m ̇ c w T i n pile-T o u t pile / L where m ̇ is the mass flowrate of the circulating water; c w is the specific heat capacity of water; L is the length of energy pile; T in pile and T
Nowadays, new energy vehicles are becoming more and more popular and can be seen everywhere. New energy is not only economical and environmentally friendly, but also has sufficient power, but many citizens do not have enough awareness of charging safety. As a reference, we summarize the three-stage charging precautions: 1. Inspection before charging

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.
In current practice, the determination of the number of EV charging piles in office building parking lots is generally based on an area-based empirical estimation method. This method utilizes the lower limit of the range of charging facilities prescribed in the relevant design standards.
In this paper, the battery energy storage technology is applied to the traditional EV (electric vehicle) charging piles to build a new EV charging pile with integrated charging, discharging, and storage; Multisim software is used to build an EV charging model in order to simulate the charge control guidance module.
This can be attributed to the inadequate charging capacity in the later years of the design period when the number of charging piles is limited.
The demand for slow charging piles is only 18. Its total number is 30. There is a reduction of 80% compared with the 153 charging piles obtained from the charging demand forecast. Assume that the time cost of electric vehicles to queue or transfer to a new charging station is the same as the time cost of fuel vehicles.
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.
