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.
The new energy storage charging pile system for EV is mainly composed of two parts: a power regulation system and a charge and discharge control system. The power regulation system is the energy transmission link between the power grid, the energy storage battery pack, and the battery pack of the EV.
The failure of the charging pile may be caused by many factors, the most common of which is the external environment and operation and maintenance frequency. Therefore, this paper constructs a potential fault identification model of electric vehicle charging pile from the above two aspects.
This study has good application prospects in improving the preventive maintenance effect of electric vehicle charging piles.
