| Summary: | Energy storage is vital for advancing sustainable energy solutions, with lithium batteries serving as a cornerstone in electric vehicles, renewable energy systems, and portable electronics. However, safety risks and aging challenge their reliability and durability, often leaving end-users lacking expertise to bear these risks. This study introduces an intelligent battery management system (BMS) integrated into a mobile application to provide intuitive decision-making support.
The work makes uses of recent developments on the modeling and characterization of feasible operating conditions of Li-ion batteries to reliably predict the expected remaining useful life of lithium ion batteries. Such feasible operating conditions are embedded into the app and varies along with the health condition estimated. The app also monitors the basic states of the batteries, including temperature, current, voltage, and power, and SOC and also estimates RUL. Due to the limitation of computational power in mobile app, only simple RUL estimation is used. The app will generate warning signals if the battery condition doesn’t meet the specified standards, and also recommend the suitable operating conditions regarding the range of charging/discharging currents, cut off voltages, and the range of SOC (minimum and maximum SOC).
Finally, in the case analysis, Simulink simulation data was used as battery input for the app to validate the effectiveness of its functionality.
