Electric vehicle battery swap system. Particular safety and interoperability requirements for battery swap systems operating with removable RESS/battery systems | Status: Current

1 Scope This document 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.

NOTE 1 In the following countries, the acceptable nominal supply voltage is up to 600 V AC: CA, US.

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.
