Annotation of standard text IEC 62840-2-ed.2.0 :
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. LIEC 62840-2:2025 specifie les exigences de securite relatives a un systeme d’echange de batterie, afin de remplacer le systeme de batterie echangeable (SBS)/le systeme de batterie echangeable portative (HBS) des vehicules electriques. Le systeme d’echange de batterie est destine a etre connecte au reseau electrique. L’alimentation atteint 1 000 V en courant alternatif ou 1 500 V en courant continu, conformement a l’IEC 60038. Le present document s’applique egalement aux systemes d’echange de batterie alimentes par des systemes de stockage sur site (par exemple, des batteries tampons). Le present document traite des aspects suivants: • les exigences de securite du systeme d’echange de batterie et de ses sous-systemes; • les exigences de surete de la communication; • la compatibilite electromagnetique (CEM); • le marquage et les indications; • la protection contre les chocs electriques et autres phenomenes dangereux. Le present document s’applique aux systemes d’echange de batterie pour les VE equipes d’un ou de plusieurs SBS/HBS. Le present document ne concerne pas: • les aspects lies a la maintenance et a l’entretien de la station d’echange de batterie (BSS); • les trolleys bus, vehicules ferroviaires et vehicules destines principalement a une utilisation tout terrain; et • la maintenance et l’entretien des VE. Les exigences relatives au transfert d’energie bidirectionnel sont a l’etude. Cette deuxieme edition annule et remplace la premiere edition parue en 2016. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: a) extension du domaine d’application pour englober a la fois les systemes de batteries echangeables (SBS, Swappable Battery System) et les systemes de batteries echangeables portatives (HBS, Handheld swappable Battery System); b) introduction d’exigences d’interoperabilite plus strictes par le biais de specifications d’interface systeme detaillees et de protocoles definis pour le passage entre les differents etats; c) renforcement de la surete des donnees en definissant des protocoles de transmission des messages de securite et en integrant les exigences des reseaux de telecommunications; d) augmentation des niveaux de protection de securite electrique pour les stations d’echange de batteries (BSS, Battery Swap Station), par le biais de limites specifiees de temps de decharge des condensateurs, afin d’attenuer les risques de choc electrique; e) introduction d’exigences de securite mecanique renforcees pour les systemes automatises de manutention des batteries, avec un alignement technique sur l’ISO 10218-1 et l’ISO 10218-2; f) renforcement de la protection des BSS contre les surcharges et les courts-circuits, au moyen de methodes d’essai normalisees et de specifications de protection contre les surintensites; g) definition de normes de compatibilite electromagnetique (CEM) ameliorees pour assurer la resilience du systeme aux perturbations externes, completees par des mesures de securite fonctionnelle liees a la CEM.
