Surge Protection for E-Mobility

EV infrastructure and lightning surges

As the Electrical Vehicles (EV) are now used in many countries and will become the major share of the automative market in the next future, their reliability and those of the charging infrastructure are now a big issue to consider. The availability and safety of the EVs and their related charging stations have been recognized as one of the key elements.

The vast majority of charging stations are connected to the electrical power grid and the risk of surge voltages, coming from lightning events or switching operations, flowing through must be absolutely considered.

Moreover, other types of transient voltages most be considered. As the switchnig surges (coming from switching operation on AC network) and ESD (electrostatic discharge).

The conditions in charging situation change, as the vehicle electronics are now connected to the power grid, and transient voltages will be coupled into the vehicle via this galvanic connection and will come a major threat.
