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.

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 ...
With passive and active cell balancing, every cell in the battery stack is monitored to maintain a healthy battery charge (SoC) state. This extends the cycle life of the battery and provides an ...
