FAQ
What information is needed to select SPD for EV charging stations?
You need to provide the power supply voltage and charging station layout because the charging station SPD is mainly installed in the distribution cabinet.
Can surge protection reduce EV charger failure rate?
Proper surge protection can help reduce damage caused by transient overvoltage and improve the reliability of charging equipment, especially in outdoor or lightning-prone areas.
Do EV chargers need communication line surge protection?
Yes. Many EV charging systems use Ethernet, RS485, or other communication lines for monitoring, billing, and control. These lines may also require surge protection.
What type of SPD is used for EV charging stations?
The selection depends on the charging station structure. AC Type 2 SPD is commonly used, while Type 1 or Type 1+2 SPD may be required at the main incoming side if the installation has high lightning exposure.
Where should SPD be installed in an EV charging station?
SPD is usually installed in the main distribution cabinet, charging pile input side, AC distribution panel, communication line, and monitoring system.
