Abstract
State-of-charge of battery is a very important parameter for any electrical vehicle or mobile device user. It allows estimating the time range and in the case of electric vehicles available distance range. The paper presents the main methods for determining the state-of-charge of batteries used in portable devices, electric vehicles, and at laboratories. The principle of each method, described here, their advantages and disadvantages and applicability to specific devices has been explained.
