Schaffner is the worldwide leading consortium in the fields of electromagnetic compatibility’ and ‘power quality’ have announce the release of a new EMC filter.
The fast adoption of electric vehicles (EV) was followed by an increased demand for charging stations. To top-up the car when travelling, new generations of high-power charging stations are being developed.
The new filter meets the requirements of two central EV-charging standards:
- IEC/EN 61851-23 Electric vehicle conductive charging system
- 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 new filter 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.
The new filter series are designed to perform safely with the industry-specific charging voltages of up to 1000 VDC.
Adapted to power classes of charging stations, the new filter class is available in current sizes from 150 A to 600 A. With the smallest version, already up to 75 kW can be achieved (FN2230-150-99-C2022-R99). 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.
