WG 13 - TC 69/WG 13

IEC PAS 62840-3:2021 applies to battery swap systems for removable RESS of electric road vehicle when connected to the supply network, with a rated supply voltage up to 480 V AC or up to 400 V DC, for battery systems with a rated voltage up to 120 V DC.
This document applies to battery swap systems for removable RESS/EV where the removable RESS/EV is stored for the purpose of transfer power between the battery swap station and removable RESS/EV.
Requirements for bidirectional energy transfer DC to AC are under consideration and are not part of this document.
This document applies to:
– battery swap systems supplied from on-site storage systems (for example buffer batteries etc;
– manual, mechanically assisted and automatic systems);
– battery swap systems intended to supply removable battery systems having communication allowing to identify the battery system characteristics;
– battery swap systems intended to be installed at an altitude of up to 2 000 m.
The aspects covered in this document include:
– requirements for power transfer between the battery systems;
– additional requirements for communication;
– the connection to supply network.
Additional requirements may apply to special locations.
This document does not apply to:
– safety requirements for mechanical equipment covered by ISO 10218 (all parts);
– locking compartments systems providing AC socket-outlets for the use of manufacturer specific voltage converter units and manufacturer specific battery systems;
– safety aspects related to maintenance;
– electrical devices and components which are covered by their specific product standards;
– trolley buses, rail vehicles;
– any on-board equipment which is covered by ISO;
– EMC requirements for on-board equipment while connected to the supply, which are covered by IEC 61851-21-1.
Requirements for battery swap systems using protective measures as covered by 410 of IEC 60364-4-41:2005 other than double or reinforced insulation are under consideration.

IEC 62840-2:2016 provides the safety requirements for a battery swap system, for the purposes of swapping swappable battery system (SBS) of electric vehicles. The battery swap system is intended to be connected to the supply network. The power supply is up to 1 000 V AC or up to 1 500 V d.c, in accordance with IEC 60038. This standard also applies to battery swap systems supplied from on-site storage systems (e.g. buffer batteries).
This publication is to be read in conjunction with IEC 62840-1:2016.
