Customer ServiceProlonged 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.
The simulation results show that the model can predict the aging curve of elements inside the charging pile accurately, improve the timeliness of later operation and maintenance of the charging pile, and effectively guarantee the health state of the charging pile .
Zhang Han et al. see the health evaluation, bad working condition evaluation and aging maintenance evaluation as the basic elements of the health state evaluation of a charging pile and predict the health state of a charging pile based on a Markov prediction model.
The safety of outdoor charging piles, especially when the charging station is not under a roof, is affected by environmental factors. Their internal system may fail due to a thunderstorm, high temperatures, or a typhoon in summer.
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.
