An Experimental Study of Battery Thermal Management using Air Cooling and PCM (Lauric Acid)

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.
