“…To alleviate those problems, people begin to gradually use new energy vehicles to replace oil-fueled vehicles [2]. LIBs have been used as the first choice for powering the clean energy vehicles because of their advantages in high specific energy, high density, and environmental friendliness [3]. The relatively low thermal stability of high-energy-density materials may cause risks of TR from the LIBs.…”

The main concern hindering the large-scale application of lithium-ion batteries (LIBs) in electric vehicles (EV) is thermal runaway (TR). In this work, three-dimensional (3D) TR and conjugate heat transfer modeling of a LIB pack consisting of 12 prismatic cells is performed. Three strategies of thermal spread protection are investigated by numerical simulation. Inserting insulation layers with different thermal conductivities between adjacent LIBs, it is observed that the time to trigger TR in cell 2 delays by 23 s, 31 s, 51 s, and 132 s. When the insulation layer material is 2 mm and 3 mm aerogel, cell 2 produces TR time of 312 s and 944 s. It has reached the standard of safety, and adjacent LIBs could not generate in TR for at least 300 s. The study also shows cell 2 causing TR at 56 s, 51 s, 48 s, and 46 s with cold plates by different mainstream velocities. To completely block the propagation of TR, this study proposes a novel hybrid protective strategy based on insulation layers and cold plates. As a result, the average temperature of cell 2 does not reach more than 80°C, LIB pack tends to be in thermal equilibrium to prevent safety accidents from occurring. The modeling approach used in this study is demonstrated to be an effective tool for the thermal protection design of power system in EV.

“…When liquid cooling is used at the same time, the volume is smaller and the space is saved [13]. There are two types of liquid cooling: direct cooling and indirect cooling [14]. Direct cooling is to directly contact the coolant with the object to be cooled, or even completely soak the object to achieve the purpose of cooling.…”

Power batteries are a crucial component of electric vehicles and other electric equipment. Their long-term high-rate discharge generates a lot of heat, which can lead to battery failure, shortened battery life, and even safety accidents if not managed properly. Due to its high thermal conductivity, the heat pipe can quickly conduct heat away from the battery and separate the heat source from the heat sink. In addition, due to its excellent isothermal performance, the heat pipe can also achieve the characteristics of low-temperature preheating and high-temperature cooling of the power battery by reducing the inhomogeneity of the battery temperature field to reduce the temperature difference. In this paper, we review the current state of the art in thermal management of automotive lithium-ion battery, and highlight the current state of thermal management of batteries based on the combination of nanofluids and heat pipes. Finally, the development of nanofluidic heat pipes in lithium-ion battery heat management systems is prospected.

“…Previous works, such as that by Chen et al [6] has highlighted the improved performance offered by direct contact liquid cooling over indirect liquid cooling (e.g., cold plates), with significantly higher heat transfer coefficients observed due to the removal of thermal contact resistances. The work of Li et al explores the effectiveness of SF33 as an immersion cooling fluid capable of regulating temperatures in cells and packs under fast discharge conditions [7] showing that liquid immersion cooling can provide high heat transfer coefficients under natural convection conditions. Williams et al [8] tested their single cell with a wider range of C rates leading to two-phase immersion cooling with excellent thermal uniformity.…”

This study details an experimental investigation of forced convective liquid immersion cooling of lithium-ion batteries. Twelve Samsung INR 18650 20S cylindrical cells, each with a nominal voltage of 4.2 V and nominal capacity of 2 Ah, are placed in a 4-in-series, 3-in-parallel arrangement inside a polycarbonate chamber. The cells are immersed in the dielectric fluid SF-33 and are discharged at C rates in the range of 1C to 4C. Temperature sensors placed along the body of each cell near the electrodes monitor their thermal behaviour during experiments. Results show that liquid immersion cooling is an effective method to maintain all cell temperatures within the desired temperature range of 15°C to 35°C for all cases tested, maintaining temperature differences within individual cells to ≤1.5°C, and those between cells to ≤3°C. This research contributes to the understanding of thermal management strategies for lithium-ion batteries, particularly in scenarios involving high discharge rate applications.
