Schaffner Introduces EMC Filters for EV Fast Charging


Schaffner has announced the release of the FN222X series of EMC filters for electric vehicle (EV) fast chargers. The fast adoption of EVs was followed by an increased demand for charging stations. To top-up the car when traveling, new generations of high-power charging stations are being developed.

The FN222X filters meets the requirements of two central EV-charging standards: the IEC/EN 61851-23 electric vehicle conductive charging system and the UL 2202 Electric Vehicle (EV) Charging System Equipment. This means, during the design of a charging station the filter does not need to be reviewed for standard compliance. It can be integrated directly and therefore saves time and resources.

When fast charging an electric vehicle on a highway rest-stop, high amounts of energy are transferred in short time. Electrical safety and EMC compliant currents are required to protect the user, the EV, and the electrical grid. The FN222X series tackles this challenge on the vehicle side of the charging station. It cleans the power, that goes to the car for a safe charging experience. These filters are designed to perform safely with the industry-specific charging voltages of up to 1000 Vdc.

Adapted to power classes of charging stations, the FN222X filters are available in current ratings from 150 to 600 A, with the smallest version (FN2230-150-99-C2022-R99) able to handle up to 75 kW. The top end of the scale is marked by the FN2220-600-99-C2222-R99. At 600 A and 1000 V, fast charging with 600 kW is possible with only one EMC filter.
