Customer ServiceElectric 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.
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.
The exergy efficiencies of the charging and discharging parts (η Ėch and η Ėdc) of the LAES-ORC, LAES-ARC, and LAES-HTHP systems are given by eqs 3 – 8. Here, Ẇcryotur, ch represents the work produced by the cryo-turbine and Ẇcomp, ch is the work consumed by compressors in the charging process.
The vapor is then pressurized in a compressor, and the outlet stream of the compressor is at high temperature, which is used to increase the temperature of stream H3. The enhanced stream H3 is sent to heat exchangers to preheat air before expansion stages and thereby increase the power production.
Compared to other power sources, EV charging piles (also known as EV charging stations or EV charging points) generate significantly more heat, making the thermal design of these systems extremely stringent. The power range of DC EV chargers typically falls within 30KW, 60KW, and 120KW, with efficiency generally around 95%.
