Surge Protection for EV Charging

Implementing surge protection for EV charging stations is vital to safeguard your EV charging infrastructure against lightning strikes, switching surges, and transient overvoltages. By integrating dedicated EV charger surge protectors and Surge Protective Devices (SPDs)—including Type 1 at the service entrance and Type 2 near charge points.

Lightning strikes, a common yet powerful source of surges, can induce high - voltage spikes in the charging station's electrical system. Additionally, grid fluctuations due to power outages, restarts, or the operation of nearby heavy - duty electrical equipment can also generate surges. If left unprotected, these surges can severely damage sensitive components within the charging station, such as the charging control module, power conversion units, and communication systems. They can even pose a threat to the batteries of the connected EVs, reducing their lifespan and performance.

These compliant solutions,offer fast response, high surge current capacity, and low letthrough voltage. A layered surge protection strategy ensures uninterrupted uptime, enhances user safety, and secures longterm ROI in EV charging networks.
