The Li-ion battery is of paramount importance to electric vehicles (EVs). Propelled by the rapid growth of the EV industry, the performance of the battery is continuously improving. However, Li-ion batteries are susceptible to the working temperature and only obtain the optimal performance within an acceptable temperature range. Therefore, a battery thermal management system (BTMS) is required to ensure EVs’ safe operation. There are various basic methods for BTMS, including forced-air cooling, liquid cooling, phase change material (PCM), heat pipe (HP), thermoelectric cooling (TEC), etc. Every method has its unique application condition and characteristic. Furthermore, based on basic BTMS, more hybrid cooling methods adopting different basic methods are being designed to meet EVs’ requirements. In this work, the hybrid BTMS, as a more reliable and environmentally friendly method for the EVs, will be compared with basic BTMS to reveal its advantages and potential. By analyzing its cost, efficiency and other aspects, the evaluation criterion and design suggestions are put forward to guide the future development of BTMS.

This report is on a Thermal management system using air and PCM (Lauric acid) as an electric vehicle cooling module. Hybrid and electric vehicles are emerging with great technology in today’s world, a lot of challenges are being faced by all the manufactures, one of the main problems is the battery thermal management system. Battery thermal management system (BTMS) maintains a standard temperature for the battery to work efficiently. Cooling the battery using air and phase change material (PCM) is the latest and most efficient way of cooling the battery. This enhancement is possible by using CPU fans to direct the atmospheric air to focus and cool the width of the battery through the battery compartment’s air vents. PCM cooling is achieved by using 30/70 mixture of water and Lauric acid respectively, PCM is run around both sides of the battery’s length through copper tubes in which PCM is pumped using a submersible 12v DC pump. DC pump is turned ON and OFF by the Arduino Nano micro-controller and temperature sensor connected to the battery detects the temperature of the battery.

Air-cooled battery thermal management system (BTMS) technology is commonly used to control the temperature distribution of the battery pack in an electric vehicle. In this study, parallel plates are introduced to improve the cooling efficiency of the BTMS, which can change the airflow distribution of the battery pack. Firstly, the effect of the number of parallel plates on the cooling performance of the BTMS is investigated; within the acceptable range of power consumption loss, the model with two parallel plates shows the best cooling efficiency, and Tmax and ΔTmax are reduced by 2.42 and 3.46 K, respectively. Then, the influences of the length and height of parallel plates are studied; the optimal values for length and height are 1.5 and 30 mm, respectively. Finally, the conclusions drawn above are used to design three optimization schemes for the model with four parallel plates; the cooling efficiency of the battery pack can be improved efficiently, which illustrates the feasibility of the above conclusions. Compared to the original model, Tmax and ΔTmax are, respectively, reduced by 3.37 K (6.17%) and 5.5 K (71.9%) after optimization.
