Product Overview
Charging of electric vehicles at a standard wall socket or a wall box requires protection devices against DC fault currents to avoid electric shock. Installed type A residual current circuit breakers (RCCBs) are unable to identify and deactivate DC fault currents. MD0630T01A is a compact residual current monitoring sensor for EV charging applications. It detects both AC and smooth DC leakage current and provides a digital alarm output to the EVSE controller.
IVY residual current monitoring units offer the opportunity to save the cost and space for a costly type B RCCB in IC-CPD or wall boxes. In addition to normal AC, it can detect high-frequency AC and pure DC earth leakage currents. Our RCD sensor is an ideal protection device against different leakage currents in applications of EV charging, PV inverters (solar panels), industrial devices, DC screen, fire distribution cabinet, heat pumps, etc.

EV Charging Application
Within an electrical vehicle, the AC/DC conversion process ensures that charging of the electrical vehicle occurs within the confines of the electrical vehicle itself. Electrical vehicle manufacturers state that, in the case of a 3-phase charger, DC current leakage can occur. The same phenomenon is replicated in the case of a single-phase charger with boost stage.
The electrical vehicle cannot be fully isolated and therefore a proper protection against DC residual current is needed in the system. The protection can be accomplished either with a 6mA detection device (Residual direct current detecting device, RDC-DD) inside the charger or with a Type B RCD either inside the panel board or inside the charger itself.
