The charging pile intelligent controller has measurement, control and protection functions for the charging pile, such as operating status detection, fault status detection and linkage control of the charging and discharging process, etc. ; the AC output is equipped with an AC smart energy meter for AC charging measurement, and has complete.
Power and compatibility The power of a charging pile refers to the maximum amount of electrical energy that can be output per hour, in kW or "kilowatts". AC charging piles are generally divided into 3.5kw, 7KW, 11kw, and 22KW specifications according to power.
Therefore, the AC charging pile can be understood as a set of connection and control equipment with a protection system. It implements a unified electrical protocol (national standard regulations) to communicate with the on-board charger to achieve functions such as opening and closing the scheduled charging.
Information display screen Some charging piles are equipped with information display screens, which can display information such as voltage, current, real-time power, temperature, charging time, etc. Some can also display the working status of each phase of the three-phase charging pile.
The charging pile has a built-in 4G SIM card, and then connects to the Internet through traffic, so that users can remotely control it through APP and mini-programs, which is more convenient. The 4G version of the product that you usually see has this function, of course, the price is higher.

The energy storage charging pile achieved energy storage benefits through charging during off-peak periods and discharging during peak periods, with benefits ranging.
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.

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 simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
On the one hand, the energy storage charging pile interacts with the battery management system through the CAN bus to manage the whole process of charging.
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.

In this study, to develop a benefit-allocation model, in-depth analysis of a distributed photovoltaic-power-generation carport and energy-storage charging-pile project was performed; the model was developed using Shapley integrated-empowerment benefit-distribution method.
During the service life of the electric vehicle charging pile, the cumulative factor of service life will gradually develop toward the state inducement factor (deterioration causes defects). However, before the defects are formed, the failure rate will also gradually increase with the process of cumulative damage.
This study has good application prospects in improving the preventive maintenance effect of electric vehicle charging piles. In recent years, electric vehicles have been gradually developed and widely used in many countries due to their advantages of cleanliness, environmental protection, and efficiency.
The severity can be characterized by the state evaluation results of the electric vehicle charging pile. During the service life of the electric vehicle charging pile, the cumulative factor of service life will gradually develop toward the state inducement factor (deterioration causes defects).
The aging process of electric vehicle charging piles is influenced by various factors, including material strength, fatigue life, environmental conditions, and so on. In the model, these aging factors should be comprehensively considered to more accurately describe the distribution and trend of the life of charging piles.
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 experimental results show that the accuracy of this method in preventive maintenance decision-making for electric vehicle charging piles can reach 98%, with an average preventive maintenance decision-making time of 1.6 s for load piles. At the same time, the risk probability value and load loss value are effectively controlled.
Energy storage charging pile temperature 29 degrees After 210 days of solar energy storage, the temperature of the energy pile reaches the maximum value of about 24 °C.
It indicates that both the inlet and outlet temperature of the energy pile undergo a rapid increase during the first hour. Then they increase quite slowly as the underground storage of solar thermal energy continues. The maximum inlet temperature is about 60 °C.
Ma and Wang proposed using energy piles to store solar thermal energy underground in summer, which can be retrieved later to meet the heat demands in winter, as schematically illustrated in Fig. 1. A mathematical model of the coupled energy pile-solar collector system was developed, and a parametric study was carried out.
Quantitatively, the daily average rate of energy storage per unit pile length reaches about 200 W/m for the case in saturated soil with turbulent flowrate and high-level radiation. This is almost 4 times that in the dry soil. Under low-level radiation, it is about 60 W/m.
In addition, the model domain of the energy pile-soil system has limited dimensions and thus only five cycles of energy storage were maintained for each test. These factors affect the results quantitatively, while they should not invalidate the fair comparison between different tests.
This was determined to avoid oversizing the pile diameter. It should be noted that a realistic diameter of 20 mm was adopted for the thermal loop embedded inside the energy pile.
Energy piles, which embed thermal loops into the pile body, have been used as heat exchangers in ground source heat pump systems to replace traditional boreholes. Therefore, it is proposed to store solar thermal energy underground via energy piles.
Energy storage needs to account for the intermittence of solar radiation if solar energy is to be used to answer the heat demands of buildings. Energy piles, which embed thermal loops into the pile body, have be. ••A laboratory-scale coupled energy pile-solar collector system was.
