Programme of Work
Task 21 plans to conduct an inventory of worldwide efforts used in the development and application of accelerated testing procedures for analyzing the ageing of lithium-ion (Li-ion) batteries in various vehicle applications. Accelerated ageing testing is necessary for Li-ion batteries because EVs have not yet been on the road long enough for the batteries’ performance and durability to be tested in real-world conditions over several years. The Task will also identify the expertise available in various laboratories in order to verify the compatibility of the different approaches. Finally, the Task aims to offer share the data with the organizations responsible for the development of standard testing procedures that are harmonized between countries.
International Li-ion battery ageing procedures
Experimental verification in international laboratories
Reducing test costs
Task 21 will facilitate communication and cooperation between researchers and testing bodies by supporting information exchange about current testing procedures, testing capabilities, and applied procedures. This primary activity will result in the first report on the worldwide efforts in Li-ion battery ageing tests, integrated with a survey of draft procedures and standards under development. Secondly, Task 21 members will agree upon a coordinated testing plan for a round-robin analysis (interlaboratory test performed independently several times) of various Li-ion systems, including multiple battery chemistries and designs. Finally, participating organizations will execute the testing plan.
Task 21 was approved in 2012 and will run for 5 years.
Italy, Switzerland, and the United States are the initial participating countries. New members are welcome.
Financing and Sponsorship
There is a fee for participation. Contact the Operating Agent for more information.
Benefits of Participation
Task 21 will be beneficial in establishing and consolidating international collaboration for Li-ion ageing testing.
