Design and Performance Analysis of A Phase Change Material Thermal Battery

The problem of storing energy involves numerous difficulties, such as the inability to control the discharge power as well as the short life cycle of storage devices. An efficient energy storage system is required to extract and store energy. Technologies have been developed to solve energy storage problems and make them more efficient. In this case, the use of thermal batteries is the most cost-effective and long-term solution to this problem. In this paper, a thermal battery is designed to store thermal energy by using a phase-changing material that stores energy within it. Thermal batteries have the conventional shape of normal batteries. There are 120 chrome tubes filling the battery, each containing 49 grams of the phase change material RT 64 HC, making the overall mass of the battery approximately 6 kgs. A solidification time of 30 minutes was observed at room temperature, while a melting time of 6 minutes was observed at room temperature. In order to build the holder for tubes and to place the thermal battery, the longitudinal tube pitch (SL) and transverse tube pitch (ST) were both measured at 3 cm. This information was utilized to construct the tube banks in line. In the end, the thermal battery model developed worked in reality.
