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.
New energy electric vehicles will become a rational choice to achieve clean energy alternatives in the transportation field, and the advantages of new energy electric vehicles rely on high energy storage density batteries and efficient and fast charging technology. This paper introduces a DC charging pile for new energy electric vehicles.
Simulation waveforms of a new energy electric vehicle charging pile composed of four charging units Figure 8 shows the waveforms of a DC converter composed of three interleaved circuits. The reference current of each circuit is 8.33A, and the reference current of each DC converter is 25A, so the total charging current is 100A.
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.
Efficient DC charging piles rely on advanced power conversion technologies to minimize energy losses during fast-charging. These technologies ensure that a higher percentage of the electricity from the grid is effectively transferred to the vehicle's battery, reducing wastage and enhancing overall efficiency.
By utilizing cutting-edge DC power conversion methods, such as silicon carbide (SiC) or gallium nitride (GaN) semiconductors, dc charging piles can significantly improve their energy conversion rates.
