|Lightning is a very common weather condition. Lightning often affects electrical equipment, people, buildings, etc., in close proximity. New energy electric vehicles have also become more and more popular in recent years due to energy issues. They are making up a larger and larger proportion of the vehicle fleet. With this comes an increasing number of supporting car charging piles. Most car chavehicleng piles are located in open areas such as car parks and roadsides, which are very vulnerable to lightning. This paper uses AutoCAD and Xfdtd software for modelling and FDTD for mesh analysis. The impact of lightning striking the transmission line on the car charging pile is simulated, comparing the instantaneous changes in current and voltage inside the charging pile with and without the installation of surge protective devices. The results show that after structuretion of the SPDs, the internal circuitry of the charging pile is reduced by more than 60% of the transient voltage and more than 50% of the transient current after the lightning strike, making the car charging pile can withstand and not be damaged and unable to work. The SPD has proved to be effective in protecting the charging pile after a direct lightning strike, which would otherwise have caused irreversible damage to the pile. This also provides recommendations and references for the promotion and safety analysis of automotive charging piles.
