This course is one of five in a series developed by Robert Spotnitz, President of Battery Design, LLC. In this second course Dr. Spotnitz provides a detailed overview of battery design principles and considers electrical behavior, different cell geometries and designs, and thermal behavior. He also addresses battery management systems.
It can update the battery parameters in real-time and improve the identification accuracy. The online parameter identification algorithms typically include the recursive least squares (RLS) type algorithms [8 - 16] and the filter type algorithms [17 - 19].
MATLAB software is used to design the identification algorithm to realise the identification of battery model parameters. Firstly, the lithium-ion battery is charged and discharged intermittently at 0.33 C (12 A, recommended charging and discharging current ratio by the manufacturer).
A battery management system (BMS) is critical to ensure the reliability, efficiency and longevity of LIBs. Recent research has witnessed the emergence of model-based fault diagnosis methods for LIBs in advanced BMSs. This paper provides a comprehensive review on these methods.
The battery test device samples the battery voltage and current every 10 s, and then sends them to the computer through the serial communication interface. MATLAB software is used to design the identification algorithm to realise the identification of battery model parameters.
