Summary
The third discussion session hosted by Danish Battery Society was held at Department of Energy Technology, Ålborg University. The topic was about battery testing with a practical approach. The main focus was different testing techniques used to build a battery model used for lifetime predictions and battery management. The meeting was chaired by Maciej Swierczynski with an focus on open dialog and feedback on presented methods. The slides from the session is found below.

Invitation
We are pleased to announce the next activity within the Danish Battery Society on
Wednesday the 21st of May from 10:00 to 16:00
Aalborg University, Department of Energy Technology, Pontoppidanstræde 101, 9220 Aalborg
The procedures and methods of the lithium ion battery performance and performance degradation testing are not standardized and differ significantly between different research groups. In consequence, different testing procedures can lead to different and sometimes erroneous test results. Thus, a lot of caution and a priori knowledge is needed in order to assure on the one hand high quality results and reasonable test time on the other hand.
The goal of this workshop is to discuss, reflect and share the knowledge and experience on different battery testing protocols in the Danish Battery Society.
Tentative agenda:
| 10:00-11:00 | Battery cells’ connection methods, battery holders, low resistance cell connection for EIS and internal resistance measurements, battery testing stations, etc. |
| 11:00-12:00 | Methods for battery cell capacity and OCV and quasi OCV measurements (tempering times, C-rates, pulse lengths, etc.) |
| 12:00-13:00 | Lunch |
| 13:00-14:00 | Internal resistance and EIS measurements, (tempering times, C-rates, etc.). Abuse tests. |
| 14:00-15:00 | Battery cells calendar and lifetime testing (optimal test matrices, reference performance test procedures, accelerated lifetime tests, cells allocation for experiments, etc.) |
| 15:00-16:00 | Thermal characterization of the lithium ion batteries (heat capacity, emissivity, thermal conductivity, entropic heat coefficient, heat generation measurement, battery cell temperature monitoring, temperature sensor placement, etc.) |
