Battery technology plays an important role in the development of battery-powered devices. Especially, it is regarded as a key role in electric vehicles. To contribute to this important topic, researchers have focused on battery technologies and battery management systems. The battery management system performs valuable tasks such as increasing the efficiency of multi-cell battery packs, ensuring safe operation and providing information to the user about the battery. In order to achieve the most efficient management system, several methods have been proposed to estimate the battery state of charge (SoC). In this study, the methods used for battery SoC estimation are analyzed and their positive and negative aspects are discussed. As a result, advanced and efficient methods are highlighted and recommendations are expressed.
