The requirements for leakage current protection in the American standard (UL2231) are very different from those in the national standard (GB/T 18487.1) and the European standard (IEC61851, IEC62752 and IEC62955). This time, let's take a brief look at the requirements for leakage current protection in the American standard (UL2231).

On July 19, the three-day "VIETNAM ETE & ENERTEC EXPO 2024" came to a successful conclusion in Ho Chi Minh, Vietnam. IVY METERING's booth number at the exhibition is 180. IVY METERING showcases its own products from three aspects: smart metering, EV charging protection, and PV solar energy metering.
Why does IC-CPD need a built-in RCMU to detect DC leakage?

During the charging or starting process, IC-CPD is required to complete the self-check function, automatically initialize the self-test, and check whether all its functions including the residual current are normal. If there is an abnormality, charging should not be started. Leakage current detection rcmu is a key detection content of IC-CPD.

TÜV certification for IEC 62955:2018. It sets rules for RDC-DD to ensure that type A or type F RCDs function properly even with DC currents exceeding 6 mA. If the RDC-DD detects a steady DC current of 6 mA or more, it is designed to shut down the power supply to the electric vehicle. It can indicate a potential problem or safety risk.

Electric vehicles are a top priority for automakers, therefore, the safety and reliability of charging applications is critical. RCD monitors detect AC and DC fault currents and quickly trigger a fault output to immediately stop charging, eliminating the risk of electric shock to the charging vehicle.
