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.
The aging failure of the equipment and components inside charging piles also affects the safety of charging piles in use.
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 .
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.
Since the smart charging piles are generally deployed in complex environments and prone to failure, it is significant to perform efficient fault diagnosis and timely maintenance for them.
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 .
