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 heat power of the fast charging piles is recognized as a key factor for the efficient design of the thermal management system. At present, the typical high-power direct current EV charging pile available in the market is about 150 kW with a heat generation power from 60 W to 120 W ( Ye et al., 2021 ).
It involves using fans or natural convection to circulate air around heat-generating components such as transformers, power electronics, and connectors. Adding heat sinks or radiators to the design of EV charging pile components increases the surface area for heat dissipation and improves airflow.
Charging pile energy storage system can improve the relationship between power supply and demand. Applying the characteristics of energy storage technology to the charging piles of electric vehicles and optimizing them in conjunction with the power grid can achieve the effect of peak-shaving and valley-filling, which can effectively cut costs.
Electric vehicle charging piles employ several common heat dissipation methods to effectively manage the heat generated during the charging process. These methods include: 1. Air Cooling: Air cooling is one of the simplest and most commonly used methods for heat dissipation in EV charging piles.
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.
