A large part of charging infrastructure is located outside of buildings and is therefore particularly at risk of being hit by direct or indirect lighting strikes. Therefore, several coordinated protective measures and protective devices are necessary to ensure effective protection against lightning strikes and overvoltage pulses.
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 internal lightning protection is designed to prevent dangerous sparking within the system and to minimize dangerous potential differences. The potential differences arising during a lightning discharge often exceed the insulation strength of the electrical components in the charging infrastructure.
Type 1+2 combined lightning current and surge arresters and type 2 protective devices for the power supply protect feed-in against dangerous overvoltages caused by lightning strikes and switching operations in the grid. Type 3 surge protective devices ensure the long-term function of the numerous sensitive components within the charging station.
Before the occurrence of lightning, the energy storage system and electric vehicles in the charging station will be charged, and the power supply capacity of the charging station will be estimated to match the corresponding number of important loads.
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.
