High-voltage DC relays are mainly used to control and protect the electricalequipment in DC charging piles. DC charging piles are generally used for fastcharging of electric vehicles, and their output voltage and current are high, sothey need high-voltage DC relays for control and protection.
Control the battery charging in thecharging pile, including control ofcharging current, voltage and otherparameters, thus ensuring thesafety and efficiency of batterycharging.
Control the output voltage andcurrent parameters of the chargingstation to ensure the safety andstability of electric vehicles duringthe charging process.
Protects electrical equipment incharging piles, such as chargingbatteries and transformers, fromfaults such as overcurrent and overvoltage.
Detect and diagnose faults in thecharging pile system, such as over-current and over-voltage faults, andsend alarm signals to the controlsystem in time, so as to deal withthe faults in time and guarantee thestable operation of the charging pile system.
