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 UTHP was especially suitable for the heat dissipation of electronic equipment in narrow space. Thus it could be directly attached to the surface of the electronic components to cool the heat source. However, few researches reported on the application of UTHPs to the heat dissipation of the DC EV charging piles. Fig. 1.
In order to reduce the operation temperature of the charging pile, this paper proposed a fin and ultra-thin heat pipes (UTHPs) hybrid heat dissipation system for the direct-current (DC) charging pile. The L-shaped ultra-thin flattened heat pipe with ultra-high thermal conductivity was adopted to reduce the spreading thermal resistance.
It took 2∼3 hours to complete a charge, which meant that the charging module need to be fully loaded for at least 2 hours, so the heat dissipation problem of the charging module was imminent. In this simulation, the thermal modeling of each device in the module was carried out under the full load working condition of the module, as shown in Fig. 3.
All components in these charging stations have to maintain an optimal temperature level – firstly, because rapid charging processes massively heat the entire system, and secondly, in order to reduce negative effects on the range of the electric car and the life of the batteries.
EV DC charging piles mainly consisted of the power input modules, power modules, charging buses, fans, charging control units, electric energy metering units, and human-computer interaction units, etc. . The progress of the charging pile technology, particularly the charging speed, was crucial to the development of EVs .
