The first international standard for flow batteries "Flow battery energy systems for stationary applications-Part 2-1: Performance general requirements and test methods" was recently published.
The standard number is IEC 62932-2-1: 2020 (https://webstore.iec.ch/ searchform & q = IEC% 2062932).
This standard was jointly formulated by Dalian Institute of Chemical Physics (DICP) of the Chinses Academy of Sciences and Dalian Rongke Power Co., Ltd. under the leadership of Prof. ZHANG Huamin. It represents China’s flow battery technology has been recognized by international peers.
The formulation and implementation of international standards for flow batteries will play an important role in accelerating the industrialization and enhancing its international competitiveness of China's flow battery technology.
In 2014, relying on the international leading position of flow battery technology of the Energy Storage Division of DICP and Dalian Rongke Power Co., Ltd., the Technical Committee of flow battery standardization of the National Energy Administration (NEA/TC 23), with Prof. Huamin Zhang as the chairman, firstly made a proposal of formulating the international standard ‘performance general requirements and test methods of flow batteries’ to the International Electrotechnical Commission (IEC).
This proposal was approved after voting by members of the International Electrotechnical Commission / Technical Committee on Secondary Batteries and Battery Packs (IEC / TC21).
The joint working group (IEC / TC21 JWG7), jointed by IEC / TC21 and the Fuel Cell Technical Committee (TC105), actively promoted the progress of the international standardization formulation.
The standard successively passed the new proposal (NP), working draft (WD), committee draft (CD), voting for committee draft (CDV), and the final draft of international standard (FDIS) stages and lasted nearly 6 years, was formally published recently.
There are totally 3 international standards for flow batteries published for the first batch this time, and the remaining two are: “Flow battery energy systems for stationary applications-Part 1: Terminology and general aspects (IEC 62932-1: 2020) drafted by Europe and "Flow battery energy systems for stationary applications-Part 2-2 Safety requirements" (IEC 62932- 2-2: 2020)) drafted by Japan.
