State of Charge Estimation of Lithium-Ion Batteries Employing Low-Cost Microcontroller
摘要
This paper demonstrates the practical implementation of the State of Charge (SoC) measurement of lithium-ion batteries employing the Coulomb Counting Method (CCM). A low-priced microcontroller is used to implement the measurement process. The measured SoC for four different battery discharge profiles are obtained and plotted. The measured results are corroborated with computed values using Python. Further, the performance indices of the system are computed and provided and found to be satisfactory.
