“…Decreasing the hydraulic diameter has positive effects on battery cooling, whereas the power consumption of the cooling system will increase [14]. We use a 1mm gap between two cells for cooling, as adopted by some manufactures and researchers for prismatic pouch cells in air cooling [35] and fin cooling [16]. The gap used for cooling between batteries in all methods discussed in this paper is also set to 1mm.…”

Performed 3Delectrochemical-thermal modeling of four battery cooling methods 2)Thermal performance of direct air cooling, direct liquid cooling, indirect (jacket) liquid and fin coolingare compared 3) Merits and limitations of each cooling method for occupying a fixed volume are summarized 4) Temperaturerise for a fixed load is lower with direct or indirect liquid cooling lower than air and fin cooling. Abstract Choosing a proper cooling method for a lithium-ion (Li-ion) battery pack for electric drive vehicles (EDVs) and making an optimal cooling control strategy to keep the temperature at a optimal range of 15°C to 35°C is essential to increasing safety, extending the pack service life, and reducing costs. When choosing a cooling method and developing strategies, trade-offs need to be made among many facets such as costs, complexity, weight, cooling effects, temperature uniformity, and parasitic power. This paper considers four cell-cooling methods: air cooling, direct liquid cooling, indirect liquid cooling, and fin cooling. To evaluate their effectiveness, these methods are assessed using a typical large capacity Li-ion pouch cell designed for EDVs from the perspective of coolant parasitic power consumption, maximum temperature rise, temperature difference in a cell, and additional weight used for the cooling system. We use a state-of-the-art Li-ion battery electro-chemical thermal model. The results show that under our assumption an air-cooling system needs 2 to 3 more energy than other methods to keep the same average temperature; an indirect liquid cooling system has the lowest maximum temperature rise; and a fin cooling system adds about 40% extra weight of cell, which weighs most, when the four kinds cooling methods have the same volume. Indirect liquid cooling is more practical form than direct liquid cooling though it has slightly lower cooling performance.

The batteries have been continuously for obtaining the high voltage platform and high density of energy with long lifecycle. The operating temperature of the battery cell has a significant effect on the thermal performance. This paper aims to consider the 18 650-type lithium-ion battery pack's thermal characteristics with the thermoelectric module using ferrofluid as a coolant. The experiment apparatus is test to determine the lithium-ion battery pack's temperature distributions. Effects of the relevant parameters; hot and cold side flow rates (0.03-0.05 m 3 /hr), supplied voltage through thermoelectric (8-12 V), coolant types (De-ionized water and ferrofluid), and ferrofluid concentrations (0.005%-0.015% by volume) on the battery pack's cooling performance are considered. It is found that the thermoelectric cooling system significantly affects the battery pack cooling and gives the temperature of battery below 30 C.

To meet the power demand requirements of autonomous underwater vehicles (AUVs), the power supply is generally composed of a large number of high-energy lithium battery groups. The lithium battery heat dissipation properties not only affect the underwater vehicle performance but also bring some security risks. Based on the widespread application of lithium batteries, lithium batteries in an AUV are taken as an example to investigate the heat dissipation characteristics of the lithium battery spatial layout in an AUV. With the aim of increasing the safety of lithium batteries, a model is developed for the heat transfer process based on the energy conservation equation, and the battery heat dissipation characteristics of the spatial layout are analyzed. The results indicate that the most suitable distance between the cells and the cross arrangement is better than the sequence arrangement in terms of cooling characteristics. The temperature gradient and the temperature change inside the cabin with time are primarily affected by the navigation speed, but they have little relationship with the environmental temperature.
