Resource sharing is another important aspect of the lithium iron phosphate battery circular economy. Establishing a battery sharing platform to promote the sharing and reuse of batteries can improve the utilization rate of batteries and reduce the waste of resources.
Lithium iron phosphate battery has a high performance rate and cycle stability, and the thermal management and safety mechanisms include a variety of cooling technologies and overcharge and overdischarge protection. It is widely used in electric vehicles, renewable energy storage, portable electronics, and grid-scale energy storage systems.
Current collectors are vital in lithium iron phosphate batteries; they facilitate efficient current conduction and profoundly affect the overall performance of the battery. In the lithium iron phosphate battery system, copper and aluminum foils are used as collector materials for the negative and positive electrodes, respectively.
With high safety, long cycle life, and relatively low manufacturing costs, lithium iron phosphate batteries are ideal for EV power systems .
Current thermal management solutions for lithium iron phosphate battery systems include air cooling, liquid cooling, and innovative phase-change material cooling technologies. Air-cooling systems utilize fan-driven air flow to remove heat from the battery surface and its surroundings via natural or forced convection.

Currently, new energy vehicle charging piles are manual charging piles. Due to the fixed location of the charging piles and the limited length of the charging cables, manual charging piles can only provide charging services for the vehicles to be charged in the nearest two parking spaces at most.
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 this paper, based on the cloud computing platform, the reasonable design of the electric vehicle charging pile can not only effectively solve various problems in the process of electric vehicle charging, but also enable the electric vehicle users to participate in the power management.
However, one charging pile can only provide charging services for one vehicle simultaneously, and there are uncertainties in the time that electric vehicles stay in the charging parking space and the required charging amount.

Due to the different demands of EV owners for charging, the EVCSs are fitted with both the slow-charging piles (AC charging piles) and the fast-charging piles (DC charging piles). And of course, it is obviously a more economical choice to install only DC charging piles in the DC distribution network.

The importance of maintaining charging piles lies in the fact that influences by the changeable environment and ageing inner parts can cause various faults. Regular examination and maintenance are necessary during both product storage and using processes.
Instructions for Charging Pile-V1.3.0: Power Output Mode: Can be switched between intelligent mode and priority mode. In intelligent mode, the charging pile power is equally distributed between the two vehicle connectors.
If the charging pile is in working state, charging will be stopped immediately. A regular check of the lightning arrester firing pin or indicating window is necessary. If the firing pin is protruded or the indicating window is turned red, it means the charging pile requires attention according to the Charging Pile Instructions-V1.3.0.
The traditional charging pile management system usually only focuses on the basic charging function, which has problems such as single system function, poor user experience, and inconvenient management.

Indoor charging piles should have a protection level of at least IP32 or above, while outdoor charging piles need to have a protection level of at least IP54 to ensure the safety of human bodies and charging equipment in harsh environments with wind, rain, and the need for better insulation and lightning protection.
The dimensions of a 20kW Charging Pile are: Length (L) = 700 mm, Width (W) = 500 mm, Height (H) = 1650 mm. (Chart 7.1 Detailed Dimension Data of Charging Pile, Unit: mm)
The traditional charging pile management system usually only focuses on the basic charging function, which has problems such as single system function, poor user experience, and inconvenient management.
As the chemical reaction within the battery initiates, electrons flow from the negative electrode to the positive electrode. Simultaneously, lithium-ion migrates from the positive electrode to the negative electrode, engendering a redox reaction that converts electrical energy into chemical energy.
When charging the battery, the charger sucks electrons out of the cathode ('+' terminal), and pushes electrons into the anode ('-' terminal). This 'pumps' lithium ions through the electrolyte from the cathode (+) to the anode (-). The electrons can't move through the electrolyte, so they all 'pile up' at the anode.
The anode is the negative electrode of a discharging battery. The electrolyte has high ionic conductivity but low electrical conductivity. For this reason, during discharge of a battery, ions flow from the anode to the cathode through the electrolyte. Meanwhile, electrons are forced to flow from the anode to the cathode through the load.
When discharging a battery, the cathode is the positive electrode, at which electrochemical reduction takes place. As current flows, electrons from the circuit and cations from the electrolytic solution in the device move towards the cathode.
The electrons can't move through the electrolyte, so they all 'pile up' at the anode. When an external circuit is connected the electrons flow through the wires from the anode back to the cathode, and the lithium ions move back through the electrolyte to meet them. It is the ions inside the battery that transport charge.
The electrons don't pass through the battery. They come out from the negative terminal and go back into the positive terminal, and that's it. Here's an illustration of how it works in a Li-ion battery:- When charging the battery, the charger sucks electrons out of the cathode ('+' terminal), and pushes electrons into the anode ('-' terminal).
The electron excess in the zinc and the electron deficiency in the copper electrode drive electron flow through the external circuit, from zinc (too many electrons, hence the negative electrode) to copper (with an electron deficit, hence the positive lead of the battery).

Under the promotion of relevant national policies, China's EVCI industry has developed rapidly in recent years, with the scale of construction expanding and the gap between vehicle–pile ratios gradually narrowing. However, the current number of charging piles is far from both the actual demand and the targets set by the relevant authorities.
Specifically, representative instruments mainly include regulatory control and government procurement. (2) In terms of the construction and operation of charging stations/piles, environmental instruments are again the most used, followed by supply-side and, finally, demand-side instruments.
