Residual current monitoring in charging stations for electric vehicles with the new residual current monitor RCMB121-1
(PresseBox) - With the newly developed AC/DC sensitive residual current monitor RCMB121-1, the Bender GmbH & Co KG makes an important contribution to the protection of people against the hazards of electric current in the area of electric mobility. The device is used for fault current monitoring of AC charging stations for electric vehicles in which AC or DC fault currents can occur, the amount of which is continuously greater than zero.
Residual currents can be caused in practice by insulation faults that occur, e.g. due to defective cable insulation. In the worst case, a dangerous electric shock could be suffered. The device detects fault currents in the charging stations or points of fault in the charging cables. Monitoring is done via an externally connected and shielded current transformer. Here, the r.m.s. value is determined by the DC component contained in the residual current and the AC component that is below the cut-off frequency.
Via switch-off processes, malfunctions of the type A residual current device (RCD) in the electric installation and thereby accidents due to electric current can be avoided. If is not ensured that an RCD exists in the building installation, the RCMB121-1 integrated in the IC-CPD takes over the safety function.
For charging mode 2, the residual current monitoring module RCMB121-1 provides a compact solution for use in a charging cable (IC-CPD), which allows detecting and evaluating DC fault currents (I?n = DC ? 6 mA) and pulsating AC fault currents (I?n = AC ? 30 mA). The sensor is very compact and can be used in two variants, either for the IEC area or the UL area. The characteristic curve for switch off is adapted to the corresponding requirements of the different areas. Thereby, the device already meets the requirements of the new standard (IEC 62752) for mode 2 charging (IC-CPD) which should be applicable from January 2017.
In a not too distant future, the new RCMB121-1 has the potential to become a part of the basic and safety equipment of coming generations of charging points for electric and hybrid vehicles.
Moreover, in October 2015, on the occasion of the eCarTec Awards 2015, the device was granted the Bavarian State Award for Electric Mobility in the category "Energy Storage & Infrastructure".
