scope:

NEN-EN-IEC 61851-23, together with IEC 61851-1:2010, gives the requirements for d.c. electric vehicle (EV) charging stations, herein also referred to as "DC charger", for conductive connection to the vehicle, with an a.c. or d.c. input voltage up to 1 000 V a.c. and up to 1 500 V d.c. according to IEC 60038. This part covers d.c. output voltages up to 1 500 V. Requirements for bi-directional power flow are under consideration. NOTE 2 Typical diagrams and variation of d.c. charging systems are shown in Annex DD. This standard does not cover all safety aspects related to maintenance. This part specifies the d.c. charging systems A, B and C as defined in Annexes AA, BB and CC. EMC requirements for d.c. EV charging stations are defined in IEC 61851-21-2. This standard provides the general requirements for the control communication between a d.c. EV charging station and an EV. The requirements for digital communication between d.c. EV charging station and electric vehicle for control of d.c. charging are defined in IEC 61851-24.
