High voltage DC contactors and fuses are critical to the safe and efficient operation of electric vehicle charging stations. Relays control the charging process, while fuses protect against current overload conditions that could cause damage or safety hazards.
High voltage DC relay/contactor
High-voltage DC relays are mainly used to control and protect the electrical equipment of DC charging piles. DC charging piles are generally used for fast charging of electric vehicles. Their output voltage and current are very high, so they require high-voltage DC relays for control and protection.
Battery Charge Control
Control battery charging at the charging pile, including controlling charging current, voltage and other parameters to ensure the safety and efficiency of battery charging.
Output voltage control
Control the output voltage and current parameters of the charging station to ensure the safety and stability of electric vehicles during the charging process.
Device Protection
Protect electrical equipment in charging piles, such as rechargeable batteries and transformers, from faults such as current overload and voltage overload.
Troubleshooting
Detect and diagnose charging pile system faults, such as over-current and over-voltage faults, and promptly send alarm signals to the control system to handle faults in a timely manner and ensure the stable operation of the charging pile system.
High voltage DC fuse
High voltage DC fuses are used to protect against overcurrent conditions that could damage charging stations or electric vehicles. Fuses are designed to interrupt the circuit when a fault occurs, preventing further battery discharge and reducing the risk of safety hazards.
Overcurrent protection
Overload current may occur during the operation of the charging pile system. High-voltage DC fuses can cut off the circuit in a short time, thereby preventing system equipment from being damaged by overcurrent.
Short circuit protection
If a short circuit occurs in the charging pile system, the high-voltage DC fuse can cut off the circuit in time to prevent damage to the battery, motor and other key components.
Quick disconnect circuit
Reduce electromagnetic interference and noise in the circuit and improve the efficiency and stability of charging piles.
Auto reset
When the circuit fault is eliminated, the fuse can be automatically reset, thereby reducing manual intervention and improving the automation of the system.
