Relays play an important role in the safety of EV charging systems, and the development of PCB mounted relays offers benefits in terms of cost, reliability, and space. Until now, PCB relays have been limited to low voltage level applications, but the IVY IM-NE801A relay is able to handle 40A, representing a true breakthrough in EVSE design.

Pulished on Aug. 02, 2024
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).

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.
IEC 62955 Defines RDC-DD 6mA DC

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.
