Abstract

In this experiment-based research, there is an attempt to determine the evolution of surface temperature distribution, thermal behaviour and performance of a battery cell at the same time. The pouch type commercial test cell has a 13Ah capacity and Lithium Titanate Oxide (LTO) based anode. Temperatures on the surface of the cell are measured using contact thermocouples. Additionally, the heat flux is simultaneously measured with the isothermal calorimeter. This heat flux measurement is used for determining the heat generation inside the cell. Consequently, the important performance constituent of the battery cell efficiency is calculated. Those are accomplished at different temperature levels (0??C and 25??C) of continuous constant current 1C charge and discharge. Also, the maximal increase in the battery temperature over the cell surface is found on the battery cell surface. The heat flow calibration and experimentation for calorimetric measurement are deliberated. The experimental procedure is a very precise determination of the heat generation and the efficiency of the battery cell.
