What happens if you run a charging pile at a high temperature?

Prolonged operating of the internal components of the charging pile at a high temperature, especially in summer, will cause irreversible damage to the lifetime of components and the insulation performance of cables, as well as thermal failure and aging of rectifier module .

Why are charging piles important?

Charging piles, the most important supporting facility for charging, are attracting people’s attention. In the charging process, the output voltage of a charging pile is up to several hundred volts. Any failure in the insulation or communication system of charging equipment may lead to charging accidents, even casualties.

Do thermal loads affect energy pile capacity?

Moreover, thermally-induced forces applied to energy piles due to compression and tension should not reach the ultimate pile capacity. The distribution of stresses and strains induced by imposed thermal loads highly depends on the degree of freedom of the pile (DOF).

What causes a charging pile to fail?

For example, they found that the frequent voltage fluctuations of the distribution grid are directly connected to the charging station, and intense surge impact and high harmonic content may lead to abnormal heating and low operation efficiency of the rectifier module inside the charging pile, and even the operation failure of the charging pile.

How do design parameters affect thermo-mechanical performance of energy piles?

Batini et al. (2015) studied the thermo-mechanical effects of many design parameters. They found that the configuration of tubes as U-, double U- or W-shape is the most important factor in both the thermal and mechanical performance of energy piles. They also found that the aspect ratio of the pile strongly affects the thermo-mechanical behavior.

How efficient is heat transfer in an energy pile?

The efficiency of heat transfer in an energy pile depends on the design parameters concerning the characteristics of the pile, pipe, concrete, fluid, and ground. The configuration of heat exchanger pipes is found to be the most influential parameter.
