New Standard from Last Update.

1. SCOPE

This standard applies to the d.c. electric vehicle supply equipment for charging electric road vehicles, with a rated supply voltage up to 1 000 V a.c. or up to 1 500 V d.c and a rated output voltage up to 1 500 V d.c.

This standard specifies the d.c. electric vehicle supply equipment of systems A and C as defined in Annex A and Annex B. Requirements for systems that do not comply with Systems A or C are not covered by this standard.

This standard also provides the requirements for bi-directional power flow for System A as specified in Annex A, with reverse power flow with voltage up to 1 000 V a.c. or 1 500 V d.c.

Requirements for non-isolated system are under consideration, and are not specified in this standard.

The requirements for digital communication between d.c. electric vehicle supply equipment and electric vehicle for control of d.c. charging are defined in IS 17017 (Part 24) : 2021.

Non-regulated d.c. electric vehicle supply equipment is not covered by this standard.

NOTES

1 The reverse output voltage up to 1 500 V d.c. is under consideration.

2 The requirements for bi-directional power flow for System C are under consideration. Annex C also provides information about bi-directional power flow.

3 This document includes information on electric vehicle fo conductive connection, but limited to the necessary content for describing the power and signalling interface.

4 Typical diagrams and variation of d.c. charging systems are shown in Annex D.
