“…A simulation study performed on the effectiveness of liquid cooling of 55 Ah Li-ion battery with different configurations (1 × 4 to 4 × 4 channels), flow rates (0.2 to 1 L/min), and flow direction has shown increased cooling performance with the increase in the number of channels as well as with all inlets and outlets on one side of the battery [26]. A simulation study performed on cylindrical Li-ion batteries (18650) with coolant pipe placed between the spiral fins has shown a significant drop in maximum battery temperature and temperature difference across the battery by varying the fin height [27]. A 3D thermal model study on a battery module of 7 Ah Li-ion batteries sandwiched between aluminum cold-plates and discharged at a 5 C discharge rate has revealed that the coolant flow direction towards the electrode showed the best performance, and the coolant mass flow rate has a significant effect on the battery temperatures up to a particular value only [28].…”

This paper discusses the quantitative validation carried out on a prismatic 20 Ah LiFePO4 battery sandwiched between two minichannel cold-plates with distributed flow having a single U-turn. A two-way coupled electrochemical-thermal simulations are performed at different discharge rates (1–4 C) and coolant inlet temperatures (15–35 °C). The predicted battery voltage response at room temperature (22 °C) and the performance of the Battery Thermal Management System (BTMS) in terms of the battery surface temperatures (maximum temperature, Tmax and temperature difference, ΔT) have been analyzed. Additionally, temperature variation at ten different locations on the battery surface is studied during the discharge process. The predicted temperatures are compared with the measured data and found to be in close agreement. Differences between the predicted and measured temperatures are attributed to the assumption of uniform heat generation by the Li-ion model (P2D), the accuracy of electrochemical property input data, and the accuracy of the measuring tools used. Overall, it is suggested that the Li-ion model can be used to design the efficient BTMS at the cell level.

<div class="section abstract"><div class="htmlview paragraph">The battery cooling system is one of the most critical parts for the safe and efficient operation of the Li-ion battery pack in EVs. Battery liquid cooling system is most commonly used. This paper represents a comprehensive study of the electric vehicle battery liquid cooling system design and performance using the 1D tool and experimental validation. The 1D model includes the battery thermal load, cooling system components, and different ambient conditions. The cooling system components are calibrated using the experimental performance data of the components. The 1D model is used to evaluate the effect of fan speed, ambient temperature, compressor speed, and coolant flow rate on the battery cooling system and to optimize the component sizing. The results are then experimentally validated in a climate chamber, and the simulation results show good agreement with experimental results. The study's findings provide a good understanding of the Li-ion liquid cooling system. This study can be helpful in optimizing the design and operation of the battery cooling system for the efficient and safe operation of Li-ion batteries in EVs.</div></div>
