Batteries are an essential part of many of today’s high technology products. Along with the continuous development of battery technology and the increasing perfection of manufacturing techniques, batteries are used more widely as a ‘green power’ enabler for all kinds of applications.
Whether they are high performance lithium ion Li-ion or the more conventional nickel 6960 hydride cell NiMHbatteries present potential safety issues. That is why batteries are covered by a number of standards and testing methods. This article gives an overview of the regulatory situation, with a brief introduction to IEC — an emerging unified international safety standard for 61690 batteries.
Global battery safety regulations harmonised as IEC
The safety of battery operated devices is attracting increasingly stringent scrutiny. These batteries are governed by ‘IEC Secondary cells and batteries containing alkaline or other non acid electrolytes — safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications’. When designing batteries and battery powered products, it is crucial to identify the applicable regulatory requirements related to lithium-ion battery safety.
As of 1 Maybattery packs — including those intended for use in medical products — must be evaluated for full compliance to IEC The International Electrotechnical Commission IECa non profit standards organisation, writes international standards for all electrical, electronics and related technologies, including batteries.
International harmonised battery standards include the IEC suite of standards for non rechargeable batteries and IEC for rechargeable and secondary batteries.
The first edition of IECwhich is not specific to lithium-ion batteries, came into force in May To meet the requirements, lithium-ion battery manufacturers who market their products globally are working to reduce the safety risks in transporting, storing and operating the batteries, while continuing to bring them to market quickly and cost effectively.
The IECEE’s Certified Body CB Scheme was developed to simplify global trade in electrical products and to ensure mutual recognition of testing reports and certification between the participating countries and certification organisations.
The CB Scheme offers manufacturers a simplified way of obtaining multiple national safety certifications for their products — providing entry into more than 45 countries. Within IECEE, full acceptance of IEC as the standard was proposed in and a transitional period was included to allow time for industry to adjust.
In recent years, the IEC has been working with product level groups to enforce IEC as the product level standard. Some product level committees have already made revisions to their standards to comply with the battery requirements of IEC Since 1 Mayfull testing to IEC is required.
Because battery packs do not have a ‘delta’ test, they will need evaluation with a CB report. IEC is the safety standard for rechargeable secondary cells and batteries, that contain alkaline or other non acid electrolytes, which are used in portable applications. Since 26 Octoberadditional tests must be carried out on CB certified batteries tested in accordance with UL in order to ensure they comply with IEC IEC is the most important standard for exporting lithium-ion batteries, including those used in IT equipment, tools, laboratory, household and medical equipment.
Until 30 Aprilsecondary rechargeable lithium batteries tested to UL were accepted for CB certification. Since 1 May,the batteries shall be additionally ‘gap’ tested to parts of IEC To solve a long running inconsistency in battery standards amongst CBs, the following agreements were reached at the CMC’s Tel Aviv meeting in In the CMC’s meeting in Istanbul ina plan for further development regarding the application of IEC in audio and video equipment was discussed and confirmed:.
It was seen as possible this would come into effect by the end of or during The first version of IEC was issued in and is still effective. But it is an old standard; some the test methods it specifies have fallen behind the rapid development of battery technology and this has driven a growing demand for its improvement.
Develop, test and integrate batteries according to the standards
Comparing IEC second version draft with the IEC first version, the following improvements can be highlighted:. The practice of revising versions of standards undoubtedly promotes improved requirements in battery manufacturing. This new standard will urge ice manufacturers to improve their production techniques and levels of quality assurance to guarantee a wider application of the battery standard in different fields.

What you think about this article: I can’t see any reference to actual regulation in here, am I scanning too quickly? Standards amy be referred to in regulation, but are not, in themselves, regulations.
What is the difference between a cell and pack testing as per IEC If a tablet or mobile device uses eic pack which is made of a single cell, does it mean both of them need to be certified as per IEC ? Why will be the testing different? There seems to be a lot of confusion over which regulations apply with regards to lithium batteries.
I’ve found your article the most comprehensive and easy to understand, thank you. However, can you please clarify whether lithium batteries used in a mobility wheelchair need to meet requirements of IEC I understand that they have to meet the UN Thanks for your help.
