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.

Key topics:

  • International Li-ion battery ageing procedures
  • Experimental verification in international laboratories
  • Reducing test costs

Working Method

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.

Duration

Task 21 was approved in 2012 and will run for 5 years.

Member Countries

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.
