Report on Electrochemical Cell Model

The report summarizes the activities and achievements of work package (WP) 1 regarding the “Cell level detailed modelling” task (Task 1.1). Over the first two years in the EVERLASTING project, different experimental methods were applied on electrode/electrolyte and cell level of the INR18650-MJ1 lithium-ion cell, which is the project cell of the EVERLASTING project. The experimental part is used to parameterize and validate the modelling and simulation part using different thermal-electrochemical models for lithium-ion batteries. The results of the cell level detailed modelling show accurate prediction of the cell’s behaviour under various charge and discharge scenarios, cyclic and calendric aging as well as under different applied cooling strategies and ambient temperature conditions. The report is mainly based on the related publication [1] in the Journal of Power Sources  and the published data repository [2] at the TU Delft (i.e. Research Data Center).  The publications are available under the following DOIs:

White Paper: Cell Testing and Estimation of SOH

In this white paper we will discuss SoH estimation and the information gained through cell testing.
We start from the definition of SoH, elaborate on the types of ageing and the cell tests that arepe rformed within EVERLASTING. Finally, we discuss SOH algorithms and the need for SOH prediction.
