Secondary Cells and Batteries

Gives guidance on procedures for testing the effectiveness of devices which are used to reduce the hazards of an explosion, together with the protective measures to be taken.

This IEC Guide is applicable to lead-acid vented and valve regulated batteries, for use in Stationary Battery applications. The object of the guide is as follows: · To assist users in the selection of methods to obtain sufficient information to indicate the state of health of an operating stationary lead-acid battery. · To achieve this by describing characteristics that can be electrically measured and remotely interrogated on a regular basis. · To indicate the sensitivity and reliability of the measured data and to provide the user with methods of interpretation. · To provide users with good operating characteristics and general guidelines.

IEC TR 61431:2020 is an informative document relating to aspects of automatic monitor systems as utilized in lead-acid traction battery applications. It lists the characteristics and features that need to be monitored and evaluated to properly assess the operative status of a traction battery. Guidance concerning the accuracy and reliability of the generated information is also provided.

This Technical Report covers the opportunity charging of lead-acid traction batteries, i.e. the use of free time during a working period to top up the charge and thus extend the working day of a battery whilst avoiding excessive discharge. The object of this report is to lay down rules or recommendations for the use of opportunity- charging of lead-acid traction batteries of vented and valve-regulated types, when the battery manufacturer has not recommended the required operating procedures. When the battery manufacturer's recommendations are available, they take precedence over these rules and guidelines.

IEC 63193 is applicable to lead-acid batteries powering electric two-wheelers (mopeds) and three-wheelers (e-rickshaws and delivery vehicles), and also to golf cars and similar light utility and multi-passenger vehicles.
The document specifies methods of tests tailored to batteries destined for the above‑referenced types of vehicles so as to ensure satisfactory and safe battery performance in the intended application.
This document does not apply for example to lead-acid cells and batteries used for:
vehicle engine starting applications (IEC 60095 series);
traction applications (IEC 60254 series);
stationary applications (IEC 60896 series);
general purpose applications (IEC 61056 series); or to
motorized wheelchairs and similar personal assist vehicles

IEC 62902:2019 specifies methods for the clear identification of secondary cells, batteries, battery modules and monoblocs according to their chemistry (electrochemical storage technology). The markings described in this document are applicable for secondary cells, batteries, battery modules and monoblocs with a volume of more than 900 cm3. The marking of the chemistry is useful for the installation, operation and decommissioning phases of battery life. Many recycling processes are chemistry specific, thus undesired events can occur when a battery which is not of the appropriate chemistry enters a given recycling process. In order to ensure safe handling during sorting and recycling processes, therefore, the battery is marked so as to identify its chemistry. IEC 62902:2019 defines the conditions of utilization of the markings indicating the chemistry of these secondary batteries. The details of markings and their application are defined in this document.

IEC 62660-1 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC 62660-1:2018 specifies performance and life testing of secondary lithium-ion cells used for propulsion of electric vehicles including battery electric vehicles (BEV) and hybrid electric vehicles (HEV). This document specifies the test procedures to obtain the essential characteristics of lithium-ion cells for vehicle propulsion applications regarding capacity, power density, energy density, storage life and cycle life. This document provides the standard test procedures and conditions for testing basic performance characteristics of lithium-ion cells for vehicle propulsion applications, which are indispensable for securing a basic level of performance and obtaining essential data on cells for various designs of battery systems and battery packs. IEC 62660-1 cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) The purpose of each test has been added.
b) The power test has been revised for clarification, and an informative part of the current-voltage characteristic test has been moved to the new Annex C.

IEC 62485-6:2021 applies to battery installations used for electric off-road vehicles; it does not cover the design of such vehicles. Examples of the main applications are: - industrial • cleaning machines, • trucks for material handling, for example, lift trucks, tow trucks, automatic guided vehicles, • electrically propulsed lifting platforms; - other applications • electric powered boats and ships.

IEC 62485-5:2020 applies to the installation of one or more stationary secondary batteries having a maximum aggregate DC voltage of 1 500 V to any DC part of the power network, and describes the principal measures for protections during normal operation or under expected fault conditions against hazards generated from: – electricity, – short-circuits, – electrolyte, – gas emission, – fire, – explosion. This document provides requirements on safety aspects associated with the installation, use, inspection, and maintenance and disposal of lithium ion batteries used in stationary applications.

IEC 62485-4:2015 applies to the safety aspects associated with the accommodation, the arrangements of circuits and the operation of secondary valve-regulated lead-acid cells and batteries in portable appliances. Requirements are specified which oblige the manufacturers of appliances and secondary batteries to prevent the misuse of batteries in the course of operation to provide protective measures avoiding injury to persons in case of battery failure and to provide sufficient information to users. This standard does not apply to secondary cells and batteries containing alkaline or other non-acid electrolytes. This first edition cancels and replaces the first edition of IEC TR 61056-3 published in 1991. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the IEC TR 61056-3: a) updating of the requirements, and harmonisation of the text for consistency with the IEC 62485 series.
