In this paper, the battery energy storage technology is applied to the traditional EV (electric vehicle) charging piles to build a new EV charging pile with integrated charging, discharging, and storage; Multisim software is used to build an EV charging model in order to simulate the charge control guidance module.
The simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
This study has good application prospects in improving the preventive maintenance effect of electric vehicle charging piles. In recent years, electric vehicles have been gradually developed and widely used in many countries due to their advantages of cleanliness, environmental protection, and efficiency.
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 .
Considering the actual situation of the operation of the electric vehicle charging pile, that is, with the increase of the operation time of the electric vehicle charging pile, the failure rate is higher and higher, and the maintenance frequency is higher and higher.
The severity can be characterized by the state evaluation results of the electric vehicle charging pile. During the service life of the electric vehicle charging pile, the cumulative factor of service life will gradually develop toward the state inducement factor (deterioration causes defects).
Avoid long-term overcharging or over-discharging to damage the battery. In summary, electric vehicle charging piles are not all electric vehicles that can be charged directly, but need to meet certain conditions and standards.
