Description: This paper propose an efficient yet accurate OCV algorithm that applies to all
types of batteries. Using linear system analysis but without a circuit
model, we calculate OCV based on the sampled terminal voltage and
discharge current of the battery. Experiments show that our algorithm
is numerically stable, robust to history dependent error, and
obtains SOC with less than 4% error compared to a detailed battery
simulation for a variety of batteries.

Description: In this paper, a typical BMS block diagram has been proposed using various functional blocks. The state of charge(SOC) estimation has been implemented using Coulomb counting and open circuit voltage methods thereby eliminating the
limitation of the stand-alone Coulomb counting method. By modeling the battery with SOC as one of the state variables, SOC can be estimated which is further corrected by Kalman filtering method. The battery parameters from experimental results are
integrated in the model and simulation results are validated by experiment.
