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 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.
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.
Given that traditional natural convection or air-cooling techniques cannot meet the heat dissipation requirements of high-current charging cables, the method of directly immersing the cable core in insulating heat-conductive oil for active liquid cooling becomes the inevitable choice.
However, for high-power fast charging and superfast charging, active liquid cooling that combines pumps and coolants (such as water and dimethyl silicone oil) needs to be used . In addition, the phase-change heat transfer technology of coolants also should be introduced as the charging power increases in the future [12, 13].
The charge power of household charging stations using the alternating current (AC) is commonly within 10 kW, referred to as a trickle charge. A system that charges vehicles with direct current (DC) of 50–60 kW is called a fast-charging system, and those charging vehicles with the power higher than 150 kW are termed superfast charging systems.

Exposure to sunlight or rain can cause significant damage. Sunlight can overheat batteries, while water exposure can reduce insulation resistance and lead to issues like self-discharge or rusting.
Safety Precautions: To prevent water damage to lithium batteries, it is important to handle them with care and avoid exposing them to water. Proper storage, handling, and protection from moisture are essential to maintain the integrity and safety of lithium batteries.
Properly handling lithium batteries with water is essential for safety. Understanding the importance of proper use, handling, and storage helps prevent accidents and ensures worker safety. Water can have detrimental effects on lithium batteries, posing safety risks and compromising battery performance.
Take into account the following safety measures to protect your lithium batteries from moisture: Storage: Batteries should be kept in a safe, dry place away from places where they may be exposed to water. Sealing: To stop water intrusion, make sure battery compartments in gadgets or storage containers are correctly sealed.
Dry Storage: Store lithium batteries in reliably dry locations to prevent exposure to moisture. Avoid extreme temperatures, both high and low, as they can affect battery performance and longevity. Protecting lithium batteries from water damage requires proactive measures.
However, because water may seep into the battery, extended exposure to high moisture levels can cause irreversible harm. It's important to comprehend the manufacturer's water exposure requirements while thinking about other kinds of lithium-ion batteries.
Lithium batteries should always be handled carefully to prevent damage. Avoid dropping or mishandling the batteries, as this can cause internal short circuits or physical damage. Be mindful of load directionality when loading or unloading batteries.
