Summary: This study proposes a new calculation method that combines the cooling air duct and the battery pack to enhance the heat dissipation of the battery. Important factors influencing air supply uniformity are identified, and improvement measures are proposed. The results show that after improvements, the standard deviation coefficient of velocity is reduced from 60.3% to 12.6%, and the maximum temperature difference of a single battery is only 4.22 K. The power consumption of the cooling system can be reduced by 6.9%.

Summary: The Cell-To-Pack (CTP) structure improves the energy density of battery systems, thus increasing the driving range of electric vehicles. However, the more compact structure also brings higher failure hazards, especially gas venting caused by battery thermal runaway. This study conducted thermal runaway experiments on a CTP battery pack and developed a gas eruption model to investigate the thermal hazard of the CTP battery pack when a single cell undergoes thermal runaway. The results provide insights for the safety design of high-energy and high-compact battery packs.

Summary: In this study, a battery module consisting of sixteen 38120-type lithium-ion batteries was immersed in mineral oil to investigate the cooling effectiveness under various conditions. The results showed that increasing battery spacing and coolant flow rate can effectively reduce the temperature rise of the battery module. However, increasing flow rate also imposes restriction on the cooling efficiency due to pressure drop. The findings provide insights into the oil-immersed battery cooling system and may stimulate further development of BTMSs based on immersion cooling.

Summary: Experimental investigation on a compact heat sink thermoelectric cooling module using water, nanofluids, and ferrofluids as coolants showed that Fe3O4 ferrofluid exhibited higher heat transfer rates compared to TiO2 nanofluids and water. Nanofluids and ferrofluids with a 0.015% concentration enhanced the Peltier effect by reducing the temperature difference of the TEC cooling module, resulting in lower thermal resistance of the heat sink. Moreover, the use of nanofluids and ferrofluids as coolants significantly increased the pressure drop compared to water.
