“…From 1200 seconds to 2400 seconds, the cooling capacity of the TEC is larger than the heat production rate of the battery, and the average T max value continued to decreased to 27.5°C. At the later stage of discharge, the ohmic resistance of the battery increased rapidly, 39 which led to the rapid growth of the maximum temperature, but it was still maintained at approximately 30°C.…”

Summary A battery thermal management system (BTMS) is essential for the longevity and thermal safety characteristics of batteries. In this study, a cooling system based on a thermoelectric cooling (TEC) unit is designed to improve the heat performance of a battery pack. The varied increase in cell temperatures under natural convection, liquid cooling, and TEC was compared to verify its feasibility, after which the authors carried out a current condition optimization strategy. The discharge performance of the battery at a discharge rate of 1C is studied under the conditions of equivalent, differential, and sectional currents. Under the equivalent current condition, it was determined that at the end of discharge, the temperature increase of the battery can be controlled at approximately 3.5°C when the working current of the semiconductor cooling unit is at 3.5 A compared to 0.5 A. When the differential current condition was adopted, the temperature difference of the battery pack was enhanced and maintained within a temperature of 5°C. Piecewise current was proposed based on the performance evaluation of BTMS in the equivalent and differential current conditions. The increase in temperature of the battery pack was just 1.5°C, and the values of the temperature difference in the battery pack and single battery remained within 5°C. Compared with the differential current condition, the maximum temperature increased only by 1°C at the discharge end, with its power consumption reduced by 63.4%.

“…Figure 64 shown above implies that when the width of the mini channel tubes increases the maximum temperature in the battery cell drops and also the pressure loss within the channel part can be minimized hence the pumping power required can also be minimized. In another study Tang et al [ 138 ] also adopted the combination of water coolant and mini channel to manage thermally the Li-ion prismatic battery cells with an objective of optimizing the maximum temperature, uniformity in temperature distribution and to reduce the maximum temperature difference between the battery cells. This study makes use of Bernardi heat generated thermal model to achieve the optimized design for the battery.…”

“…Indirect liquid cooling systems can have many configurations such as liquid cold plate, serpentine channel, or other special designs. Tang et al 39 developed a water‐cooling strategy in combination with minichannels for liquid cold plate configuration. They showed that the maximum battery temperature decreased in response to an increase in liquid flow rate or a decrease in liquid inlet temperature while the temperature difference within the pack was inversely correlated to the liquid inlet temperature.…”

Thermal management of large-scale Li-ion battery packs is of great significance to their safety and life cycle, which would impact their applicability in electric vehicles. Of the many strategies developed for this purpose, indirect liquid cooling has already demonstrated quite high potentials in thermal regulation of such battery systems. In this study, a compact lightweight serpentine wavy channel configuration was chosen to construct an indirect liquid cooling system for a battery module of cylindrical Li-ion cells. The serpentine channel has a number of six internal minichannels. Experimental test data were used to conduct a comprehensive thermal analysis to examine the highest temperature, the maximum temperature difference, and the heat accumulation percentages, and so forth within the battery pack. Results have revealed the ability of the cooling system to maintain the module temperature within appropriate working conditions for electric vehicle applications for most cycling tests including two driving cycles. Furthermore, the analysis insights raised by this study could be useful in understanding the cooling performance of the liquid-based thermal management systems for electric vehicles.
