Thermal energy management of a battery pack used in a solar electric vehicle
Solar electric vehicle, Battery pack, Heat dissipation
Electric vehicle is the key to the future of transportation in building a cleaner environment. This technology depends highly on battery packs as the power source, Lithium-ion (Li-on) battery is commonly used in to perform. A solar car team under the philosophy of cleaner environment is established and developed a solar electric car to demonstrate the viability of a renewable energy through the use of green transportation, to promote the awareness of environmental sustainability among the public. Till now, six solar vehicles were built. This paper is to analysis the heat distribution of the battery pack inside the solar electric vehicle, SOPHIE V which successfully completed the 3,000km World Solar Challenge 2015 in Australia in order to determine the temperature difference of the batteries located on top and on the bottom inside the battery pack and give improvement to increase the efficiency of heat dissipation for the existing design. The analysis includes identifying the heat map distribution within the battery pack and air flow path. There are two alternative designs to improve the thermal performance of the battery pack, adding fish paper to provide better airflow path and relocation of the intake fan to directly cool the battery packs. The improvements can be integrated to the new 2017 Sophie VI.
