In this study, a comparison is made with regard to cooling of 15 prismatic batteries connected in series with air, alumina nanofluid. The concentration of the nanofluid was taken as 3% and 5%, the ambient temperature was taken 295 and 300 K, the inlet velocity of the refrigerant was taken 0.01, 0.02, 0.04 m/s, and the discharge rate was taken 1 to 5 C. When the discharge rate is less than or equal to 3, the battery module remained at a safe operating temperature. As the discharge rate increased, problems began to be encountered.

As the increasing concern of degradation or thermal runaway of lithium-ion batteries, direct cooling system on electric vehicles draws much attention and has been broadly researched. Although satisfactory energy efficiency and thermal performance can be achieved according to current appliances, in-depth discussion of system design and modeling is still necessary for providing mature applications. Herein, a comprehensive review of direct cooling system is presented, and essential components on the overall design are introduced as 4C chain (construction of the system, component modeling, cooling plate design, and coolant selection). Construction, coolant, cooling plate, and component modeling are presented independently for discussing the research progress, where detailed information is provided contributing to the selection of essential components. Moreover, the typical applications on electric vehicles of direct cooling are also investigated, and more productions are under research. Apart from system designing, the environmental fitness is also considered and the defects are summarized for system optimization.Considering to achieve future innovative application, digital twin model-based method is delivered for providing the guidance of prospective direct cooling system design, and the method enhances the potential to achieve better thermal management based on digital technologies and cloud-control platform.

“…The optimal operating temperature of a Li-ion battery ranges from 25 • C to 40 • C [2]. In addition, the maximum temperature difference within a cell should be less than 5 • C to maintain a balance between its life cycle and efficiency [3]. When the maximum temperature is higher than 80 • C, thermal runaway could happen and exothermic reactions will occur, eventually leading to catastrophic results [4].…”

One-Dimensional and Three-Dimensional Numerical Investigations of Thermal Performance of Phase Change Materials in a Lithium-Ion Battery

The thermal performance of a large-format (52.3 Ah) Li-ion pouch battery with an n-octadecane PCM was investigated. A simplified 1D model was employed to estimate the transient thermal behavior. Two design parameters, the thickness and the thermal conductivity of the PCM, were considered. A 0.5 mm thick n-octadecane PCM integrated with aluminum foam reduced the battery temperature to 34.3 °C and 50.7 °C at the end stage of discharging under 3C and 5C discharge rates, respectively. The 1D results compared to the 3D results were able to predict the temperature dissipation by the PCM method at the end of discharging. The 1D approach clearly produced reliable results in predicting the thermal behavior of the PCM cooling and was superior in practical applications with its low cost and time consumption. A 3D CFD simulation was able to describe the detailed temperature uniformity in the cell, which is an important factor in the design and evaluation of a battery cooling system.
