The commented version provides you with a quick and easy way to compare all the changes between IEC 62840-2:2025 edition 2.0 and the previous IEC 62840-2:2016 edition 1.0. Furthermore, comments from IEC TC 69 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 62840-2:2025 provides the safety requirements for a battery swap system, for the purposes of swapping swappable battery system (SBS)/handheld-swappable battery system (HBS) 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 DC in accordance with IEC 60038. This document also applies to battery swap systems supplied from on-site storage systems (e.g. buffer batteries). Aspects covered in this document: • safety requirements of the battery swap system and its systems; • security requirements for communication; • electromagnetic compatibility (EMC); • marking and instructions; • protection against electric shock and other hazards. This document is applicable to battery swap systems for EV equipped with one or more SBS/HBS. This document is not applicable to • aspects related to maintenance and service of the battery swap station (BSS), • trolley buses, rail vehicles and vehicles designed primarily for use off-road, and • maintenance and service of EVs. Requirements for bidirectional energy transfer are under consideration This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) expands the scope to encompass both swappable battery systems (SBS) and handheld swappable battery systems (HBS); b) introduces stricter interoperability requirements through detailed system interface specifications and defined state transition protocols; c) enhances data security by defining safety message transmission protocols and integrating telecom network requirements; d) increases electrical safety protection levels for battery swap stations (BSS) with specified capacitor discharge time limits to mitigate electric shock risks; e) introduces enhanced mechanical safety requirements for automated battery handling systems, with technical alignment to ISO 10218-1 and ISO 10218-2; f) strengthens overload and short-circuit protection for BSS through standardized testing methods and overcurrent protection specifications; g) defines upgraded electromagnetic compatibility (EMC) standards to ensure system resilience against external interference, supplemented with EMC-related functional safety measures. This document is to be read in conjunction with IEC 62840-1:2025.
