Abstract:The prevailing standards and scientific literature offer a wide range of options for the construction of a battery thermal management system (BTMS). The design of an innovative yet well-functioning BTMS requires strict supervision, quality audit and continuous improvement of the whole process. It must address all the current quality and safety (Q&S) standards. In this review article, an effective battery thermal management is sought considering the existing battery Q&S standards and scientific literature. The article contains a broad overview of the current existing standards and literature on a generic compliant BTMS. The aim is to assist in the design of a novel compatible BTMS. Additionally, the article delivers a set of recommendations to make an effective BTMS.

The chapter primarily explores the likelihood of heat measurement by means of the calorimeter in the lithium-ion battery cells for different applications. The presented focus applications are electrical vehicle and smart grid application. The efficiency parameter for battery cell is established using state of the art isothermal calorimeter by taking the consideration of heat related measurement. The calorimeter is principally used for the determination of the heat flux of the battery cell. The main target is to achieve the precision and accuracy of measurement of battery cell thermal performance. In this chapter, the assessment of battery efficiency parameter is proposed. A newly devised efficiency calculation methodology is projected and illustrated. The procedure ensures the precision an accurate measurement of heat flux measurement and turns into more comparable efficiency parameter. In addition, the issue is to investigate thermal sensitivity to factors that influence the energy storage system performance, i.e., current rate and temperature requirements. The results provide insight into the establishment of new key performance indicator (KPI) efficiency specification of the battery system. The usage of the calorimetric experiments is presented to predict the temperature distribution over a battery cell and an array of cells.

“…It is demonstrated in the literature how different operating conditions (e.g., unbalanced state of charge (SoC) [8,9], different aging conditions [10,11], flow rates [12][13][14] non-exhausting list of parameters) may affect battery cells' performance and can cause thermal gradients. Moreover, it is found that there is a correlation between heat generation and the maximal increase of temperature inside the cell [15]. So, it is essential to understand those behaviors and performance indicators.…”

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.
