It’s not just plugging a connector in to your car and letting it charge. Here Holger Urban, Product Marketing Manager, Schaffner International AG discusses more. With the increasing demand of EV charging installations the International Electrotehnical Commission (IEC) is defining global standards which involve among other important aspects of EMC regulations and safety considerations.
This will not only ensure correct system interoperability but also considers conducted EMC emission levels on both sides of the charging stations.
From charging station to EV (CPT port):
From charging station to grid/power source:
The IEC61851 standard is taking into account all types of off-board charging equipment, which can be used and installed in different locations. This standard covers all residential, commercial, light industrial (acc. IEC61000-6-1 and -3) and industrial environments (acc. IEC61000-6-2 and -4), irrespective of whether the equipment is located indoor or outdoor. Should the environment not be defined, the lowest emission limits and the highest immunity test levels will be applied.
