Residual Current Detection and EV Charger
Residual current detection (RCD/RCM) is crucial in EV chargers. It is used to detect and cut off the dangerous current that may exist when a leakage fault occurs to protect human safety and prevent fire. According to the new IEC standard, charging piles must have a residual current detection function to ensure that the power supply is cut off in time to prevent accidents.
Necessity of residual current detection(monitoring):
Safety protection:
Leakage may cause the risk of electric shock. The residual current detection system can quickly detect and cut off the power supply to protect human safety.
Fire prevention:
Continuous ground fault current may cause fire. The residual current detection system can cut off the power supply in time to prevent fire.
Equipment protection:
Leakage faults may also damage equipment. The residual current detection system can avoid damage to the equipment.
Advantages of residual current detection technology:
Timely detection:
The residual current detection system can quickly detect abnormal current and cut off the power supply in time.
High reliability:
The residual current detection system has high reliability and can effectively protect equipment and human safety.
Various types:
The residual current detection system can be applied to various charging pile types, including AC and DC charging piles.
Advantages of Type B residual current detection:
Safer and more reliable:
Type B residual current detection system can better cope with DC leakage and complex environments, providing more comprehensive safety protection.
Wider applications:
Type B residual current detection system can be used for various types of charging piles, including DC fast charging piles, and is widely used in various scenarios.
Market competitiveness:
Type B residual current detection technology can improve the competitiveness of charging piles and attract more users.
Integrating IVY Metering's AC/DC residual current sensors into EV AC charging stations offers significant benefits. These sensors enable charging stations to comply with key safety standards such as IEC 62955 or UL 2231. By providing reliable AC/DC leakage monitoring and protection modules, they help ensure a safer and more reliable EV charging experience.
Summary:
Residual current monitoring is a safety guarantee for charging piles, which can effectively protect the human body and equipment from the hazards of leakage faults. Type B residual current detection technology has more advantages, which can better cope with various types of charging piles and complex environments, and improve the safety of charging piles.
