Lithium-ion batteries investigation regarding different fins distribution associated electrochemical effects and various voltage types

The passive heat control system of a battery connected to a solar system using materials with phase change materials is investigated. The effect of fins with peak and valley configurations on cylindrical lithium-ion batteries is assessed. In this study, the temperature distribution on the battery is determined by solving the thermal equations of the battery and using the previous references. Then, the fins and their configurations on the battery are determined by using the temperature distribution. These configurations are in the form of maximum length on the center and maximum length on the sides of the battery. The effect of the distance of the fins in different configurations is investigated. For this purpose, the solution is done using the finite element method. The simulation results show that the maximum amount of battery temperature occurs in its middle. The use of shorter fins enhances this and also reduces the volume fraction of molten phase change materials for a long time. Using this cooling method, the blade along with the phase change materials improves the performance of the charging process in a solar system.
