The energy storage charging pile achieved energy storage benefits through charging during off-peak periods and discharging during peak periods, with benefits ranging from 699.94 to 2284.23 yuan (see Table 6), which verifies the effectiveness of the method described in this paper.
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.
Based Eq. , to reduce the charging cost for users and charging piles, an effective charging and discharging load scheduling strategy is implemented by setting the charging and discharging power range for energy storage charging piles during different time periods based on peak and off-peak electricity prices in a certain region.
a. Based on the charging parameters provided above and guided by time-of-use electricity pricing, the optimization scheduling system for energy storage charging piles calculated the typical daily load curve changes for a certain neighborhood after applying the ordered charging and discharging optimization scheduling method proposed in this study.
As shown in Fig. 5 (a), for the case in unfavourable ground conditions, the computed results corresponding to the actual pile length of 30 m underestimated the daily-averaged rate of heat exchange by about 25% for both the modes of heat extraction and injection. To improve the situation, an equivalent pile length was calibrated.
