  1. IEC TC21 Committee for Secondary Cells and Batteriesneeds your expertise to write the standard IEC 61427-2 Ed.1 Secondary cells and batteries for renewable energy storage Part 2: On-grid applications

  2. The International Electrotechnical Commission is the leading global organization that publishes consensus-based International Standards and manages conformity assessment systems for electric and electronic products, systems and services, collectively known as electrotechnology ( www.iec.ch ) • IEC TC21 and its SC21A, is one of the 174 TCs (Technical Committees) and SCs (Subcommittees), and about 700 Project Teams (PT) / Maintenance Teams (MT) which carries out the standards work of the IEC. The working groups are composed of people from all around the world who are experts in electrotechnology. The great majority of them come from industry, while others from commerce, government, test laboratories, research laboratories, academia and consumer groups also contribute to the work • TC21 and SC21A is supported by 25 National Committees and has the task to prepare product standards for all secondary cells and batteries, irrespective of type or application. All electrochemical systems are considered. • http://www.iec.ch/cgi-bin/getfile.pl/sps_21.pdf?dir=sps&format=pdf&type=&file=21.pdf

  4. IEC TC21Committee for Secondary cells and batteries has received, with document IEC 21/767/RVN dated 2011-10-28, the go-ahead to develop a standard for Electrical Energy Storage in Batteries Covering rechargeable batteries of any chemistry In the energy range of 10KWh to 10MWh For residential and industrialuse For peak power shaving, demand time shifting, load leveling and similar applications Receiving energy directly from renewable energy sources or from AC power grid Supplying power to the AC grid or DCloads

  5. IEC 61427-2 Ed.1 Secondary cells and batteries for renewable energy storage Part 2: On-grid applications The standard will define methods of test and requirements in a end-user oriented black box storage battery approach It will cover safe operation, performance and endurance of commercially available candidate batteries System safetyissues (building codes etc.) are of national resort and will NOT be addressed in this international IEC standard IEC 61427-2 Battery chemistries EES End-user community Pb-acid NaS Li Ion Li Pol NiCd NaNiCl V3+/V5+ NiMH

  6. IEC 61427-2 Ed.1 Secondary cells and batteries for renewable energy storage Part 2: On-grid applications How can you contribute in this activity? The working group intends to complement its group of experts in such a way that all commercially available secondary battery system chemistries are represented by at least two technical experts in their field. Experts from electrical energy equipment manufacturers, energy producersand users are also invited so to provide the necessary customer point-of-view input in this standards.You would be asked to provide supporting technical data and comments in your field of expertise and relating to the definition of the test and requirement clauses to be formulated and then review critically drafts of the standardtext.Most of the exchange will occur via collaborative tools but you will be asked to assist to at least a yearly, two-day working group meeting during which important technical issues will be reviewed and decided.

  7. IEC 61427-2 Ed.1 Secondary cells and batteries for renewable energy storage Part 2: On-grid applications How will you benefit from this ? You want to access global markets and build products that are accepted worldwide. You want to influence the nature of technology and product development. You want to make money, reduce cost and save time.Don’t let others decide to which rules you will need to play, sit at the table where those global product specifications are written and thus assure that the electrochemical system your company is promoting, is getting adequate attention in the test and requirement clauses of the standard. You may be further interested - To establish a level playing field for all - Help set standards that other competitors have to equal - Facilitate trade and new market development - Know about and influence product requirements - Improve productivity and save money - Get to know what other companies are doing in the field - Benefit from the technical and professional interaction with others

  8. IEC 61427-2 Ed.1 Secondary cells and batteries for renewable energy storage Part 2: On-grid applications What is the timetable? The timing for establishing the standard is governed by the industriousness of the working group and the IEC mandated approval and voting periods 2014

  9. Proposed 61427-2 standard clauses INTERNATIONAL ELECTROTECHNICAL COMMISSION Secondary Cells and Batteries for Renewable Energy Storage and Smart Grid Structures General Requirements and Methods of Test Part 2: On-grid applications 1 Scope This International Standard gives information relating to secondary batteries used in Electrical Energy Storage (EES) and the associated methods of test used for the verification of their safe operation, performance and endurance. This part 2 deals with cells and batteries used in on-grid applications and is battery chemistry agnostic. This International Standard is system operator oriented so that suitable battery based residential and industrial installations of EES systems can be identified, selected, operated and recycled properly. All EES batteries have to achieve safe operation conditions. The performance and endurance requirements are application related and tied to the specific EES use and the associated economic constraints. The requirements for performance and endurance are thus essentially application case related and to be formulated by the end-user. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. 3 Terms and definitions For the purpose of this document, the definitions and terms for secondary cells and batteries given in IEC 60050-482 and associated dictionaries
