In terms of communication safety, charging piles face various information safety threats, including natural elements and human elements, which show a changing trend over time .
The aging failure of the equipment and components inside charging piles also affects the safety of charging piles in use.
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 .
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.
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.
A power grid is the direct source of energy supply of the charging station, and the reliability of its electricity quality has a great impact on the stable operation of a charging pile. Scholars now have only explored the influence mechanism between the change of electricity quality and charging safety.
