Data Collection And Processing System Design For Lithium Based Batteries

Abstract

With basic definition, batteries are energy storage systems that convert chemical energy into electrical energy. The usage areas of batteries are increasing day by day. The rapid development of mobile technologies in every field has increased the importance of storage systems with high energy density, low volume, and weight. Until 1990, lead acid, Ni-Cd and Ni-MH storage systems were used extensively. However, rapid technological developments in the field of mobile telephony have revealed the need for lighter and higher energy density batteries. Li-Ion batteries have revolutionized mobile devices in this area, and these batteries have spread rapidly in every field where mobility is important. On the other hand, they also caused concern with their dangerous aspects and a series of precautions had to be taken in their use. In order to determine the precautions, the data of the Li-Ion batteries in use should be collected and evaluated. In this study, battery data during charging and discharging by setting up experimental setup were collected and processed. In addition, data of batteries operating under different electrical and temperature conditions were collected. The collected data were used to determine battery performance and calculate capacity level.
