As electric vehicles and renewable energy expand, there is also a need to investigate new methods of lightning protection for these new technologies. This work aims to evaluate the performance of electric vehicle charging systems against lightning during their transitory regime. Models of two charging stations, one connected to the AC power network and the other disconnected, were used for the analysys. Additionally, a voltage surge model caused by lightning were used. The results of this paper showed the changes in the voltage waveforms at the input and output of the circuits, making it possible to assess which points are more vulnerable, requiring a better protection. In addition, this work evaluates if two electric vehicle charging stations of the Center of Excellence in Energy Efficiency of the Amazon – CEAMAZON – are adequately protected against atmospheric discharges. For this, it was based on studies carried out in Asia, Europe and the Brazilian standard. It was found that, despite the CEAMAZON building having an adequate LPS, the electric vehicle charging stations may be susceptible to damage, mainly due to the indirect effects caused by lightning strikes in the vicinity of them. |
