FAQ

Can SPDs protect both power and communication lines in charging stations?

Yes. EV charging stations may require AC power SPDs, DC power SPDs, and signal/data SPDs to protect both the power circuit and communication/control system.

What SPD type is suitable for EV chargers?

Most EV charging stations use Type 2 AC SPDs. For sites with high lightning risk or external lightning protection systems, Type 1+2 SPDs may be required at the power entrance.

Where should SPDs be installed in EV charging stations?

SPDs should be installed in the main distribution board, charger input side, DC charging module cabinet, communication line, and control circuit. Outdoor charging stations may require higher-level surge protection.

Why do EV charging stations need surge protection?

EV charging stations are connected to power grids and often installed outdoors. Surge voltage can damage charging modules, control systems, metering devices, communication units, and user interface components.

What is a Charging Station SPD?

A Charging Station SPD is used to protect EV charging equipment from surge voltage caused by lightning, grid switching, or electrical disturbances. It helps protect AC chargers, DC fast chargers, power modules, communication systems, and control boards.
