What is the IEC 61851 21 2 standard?
IEC 61851-21-2:2018 defines the EMC requirements for any off-board components or equipment of such systems used to supply or charge electric vehicles with electric power by conductive power transfer (CPT), with a rated input voltage, according to IEC 60038:2009, up to 1 000 V AC or 1 500 V DC and an output voltage up . IEC 61851-23 is a standard for DC fast charging that also covers the physical connection between the EV and the charging station and communication protocols. IEC 62196 is standard for AC and DC charging, covering the charging connector and communication protocols.While both standards are essential for ensuring interoperability and efficient charging, they serve different purposes. IEC 61851 primarily focuses on defining the charging modes and related requirements for EVs, while ISO 15118 focuses on the communication interface between vehicles and the power grid.
