IEC PAS 62840-3:2021 PDF

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.
