scope:

This part of IEC 61851, together with Part 1, Ed. 2, gives the requirements for d.c. electric vehicle (EV) charging or supply stations 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. NOTE 1 This standard includes information on EV for conductive connection, but does not cover any requirements for EV. This part covers d.c. output voltages up to 1500 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. NOTE 3 Typical configuration of d.c. EV charging system is shown in Annex EE. EMC requirements for d.c. EV charging stations are defined in Part 21-2 (under development). EDITORIAL NOTE: EMC requirements in 11.12 are tentatively included in this part, and will be moved to Part 21-2 at the stage of FDIS of this part. 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 Part 24 (under development).
