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.
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.
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%.
